Translation Release for series 4.8

Publié: 2018-05-21 18:00:00+00:00 release

Due to a mistake in the process of generating the translations, the initial release of series 4.8 contained some unstranslated strings. We decided to make new set of releases with the correct translations even if it breaks the rule of no database updates for bug fix releases.

If you have already updated your server to the series 4.8, you need to also update the database for this bug fix release. Sorry for the inconvenient.

This release additionaly includes the Spanish Chart of Accounts which has cleaner design and is now available for the 4.8 series.

New Tryton release 4.8

Publié: 2018-04-23 18:00:00+00:00 release

We are proud to announce the 4.8 release of Tryton. This is the last release that will support Python2, as decided on the last Tryton Unconference, next versions will be only Python3 compatible.

In this way we introduced a new way of dynamic reporting. For now it's only available on sale module, but the plan is to extend it to more modules in newer releases. The effort to make all the Desktop client features available on the Web client has continued on this release. This resulted in fixing many small details and adding some missing features on the web client. Of course this release also includes many bug fixes and performance improvements. We added Persian as an official language for Tryton.

As usual the migration from previous series is fully supported. Some manual operation may be required, see migration from 4.6 to 4.8.

Major changes for the user

  • The clients show a toggle button next to the search input for all models that can be deactivated. This allows the user to search for deactivated records and to know that the model is deactivable.
Sao list with inactive records option
  • Until now, when changes on a record from a pop-up window were cancelled, the client resets it using the stored value from the server or deletes it if it was not yet stored. Now, the clients will restore the record to the state it had before opening the pop-up, which is a more expected behaviour for the user.
  • It's no longer possible to expand a node that has too much records. This is needed to prevent to consume all the resources of the client. In such case the client will switch to the form view where normally the children will be displayed in a list view which supports loading records on the fly when scrolling.
  • To help companies to be compliant with the right to erasure from the GDPR, a new wizard to erase a party has been developed. It erases personal information linked to the party like the name, addresses, contact mechanisms etc. It removes also those data from the history tables. Each module adds checks to prevent erasure if pending documents for the party still exist.
  • A name has been added to the contact mechanism. It can be used for example to indicate the name of the recipient of an email address or to distinguish between the phone number of reception, accounting and warehouse.
  • The default search on party will now also use contact mechanism values.
  • Similar to the design of the addresses which can be flagged for invoice or delivery usage, the contact mechanism received the same feature. So the code may now request a contact mechanism of a specific type. For example, it is now possible to define which email address of a party should be used to send the invoices.
  • All the matching criteria against product categories have been unified between all the modules. Any product category will match against itself or any parent category. This is the chosen behavior because it is the least astonishing.

Desktop

  • The desktop client already has mnemonic for all button but now they are also added to all field labels. This allow to jump quickly to any visible field by pressing ALT + <the underlined key>.
Tryton form with mnemonic
  • The desktop client has a new option to check if a new bug fix version has been published. It takes care of the notification on Windows and MacOS.
Tryton with the notification of a new version available
  • The Many2One fields in editable tree now show the icons to open the related record or clear the selection. This unifies the behaviour with the form view.
Tryton with Many2One icons on editable tree

Web

  • Numeric values are now formatted with the user locale and use an input of type 'number' for editing. This allows to have the right virtual keyboard on mobile devices.
  • The web client finally receives the label that positions the selected record in the list and shows the number of records in the list.
Sao toolbar with selected record label
  • The spell checking is now activated by the browser, so fields with the spell attribute defined will have spell checking activated.
  • The buttons of widgets are now skipped from tab navigation in the web client. The actions of those buttons are available via keyboard shortcuts.
  • The management of editable list/tree has been completely reworked. Now the full row becomes editable on the first click. The focus is kept on the line if it is not valid. The editing is stopped when the user clicks anywhere outside the view.
  • The sum list feature has been implemented in sao.
Sao sum of move's credit and debit
  • The same shortcuts of the Date and DateTime widgets available on tryton can now be used on web client.
  • Many2One fields are displayed on tree view as clickable link which opens the related record form view to allow quick edition.

We have pushed many small improvements which fix small jump of elements of the page:

Accounting

  • The general ledger accounts are now opened from the Income Statement rows. This allows to see the details of the computed amounts.
  • It happens that users need to customize the configuration of the chart of account that comes from a template. Until now, this would prevent any further update without loosing this customization. Now, the records that are synchronized with a template are read-only by default. A check box allows to edit the value and thus remove the record from the update process.
  • Users may create a second chart of account by mistake. There are very rare cases when such creation is valid. As it is a complex task to correct such mistake, we added a warning when creating a second chart of account.
  • Now an error is raised when closing a period if there are still asset lines running for it.
  • Until now, only one tax code was allowed per tax. This was too restrictive. For some country it was needed to create null children taxes to allow more complex reporting. Now, tax codes are no longer defined on the tax but instead they contain a list of tax lines. Those lines can define the base or the tax amount. On the report, the lines of each tax code are summed per period. All chart of accounts have been updated to follow this design.

Tax report on cash basis

The new account_tax_cash module allows to report taxes based on cash. The groups of taxes to report on cash basis are defined on the Fiscal Year or Period. But they can also be defined on the invoices per supplier.

The implementation of this new module also improved existing modules. The tax lines of closed period are verified against modification. The registration of payment on the invoice is limited to the amount of the invoice.

Spanish chart of account

The module, which was published for the first time in the last series 4.6, needs a deep cleaning. The last changes in the accounting modules raised concerns about choices made for this chart. So it was decided to temporary exclude the module from the release process and to not guarantee a migration path. The work to fix the module has started and we expect to be able to release a fixed version soon.

Invoicing

  • The description on invoice line is now optional. If a product is set the invoice report will show the product name instead of the line description.
  • The reconciliation date is now shown on the invoice instead of the Boolean reconciled. This provides more information for a single field.
  • The Move lines now show which invoice they pay.
  • An error is raised when trying to overpay an invoice.

Payment

A cron task has been added that will post automatically the clearing moves after a delay. The delay is configured on the payment journal.

Stripe Payments

  • If the customer disputes the payment, a dispute status will be update on the Tryton payment. When the dispute is closed, the payment is updated according if the company wins or loses.
  • Some missing charge events has been added. In particular, the refund event which may update the payment amount when it is partial.

Statement

account_statement_ofx

This new module adds the automatic import of OFX file as statement. The OFX format is a common format which is supported in various countries, like the United States.

Stock

  • The stock quantity was only computed per product because it is the column stored in the stock move. But it may be useful for some cases to compute the stock quantity per template. Indeed products from the same template share the same default unit of measure so their quantities can be summed. This release adds on the products_by_location method the possibility to group by product columns like the template, but also a relate action from the template which show quantity per locations.
  • When there is a very large number of locations, the tree Locations Quantity becomes difficult to use. Especially if you are searching in which location a product is. So we added the option to open this view as a list, this way it is possible to search location by quantity of the product.
List of locations with product stock
  • We found that there are two different expectation from users about the default behavior of the inventory when the quantity is not explicitly set. Some expect that the product quantity should be considered as 0. And others expect that the product quantity is not changed. So we added an option on the inventory to choose the behavior when an inventory line has no quantity.
  • Until now, the assignation process for supplier return shipment was not using children location but this did not work if the location was a view. Now we assign using the children if the location is a view.
  • The supplier shipment support to receive the goods directly in the storage location. This way the inventory step is skipped.

Project

  • Until now, only sub-projects having the same party were invoiced. Now an invoice for each different party will be created.

Sale

  • The description on sale line is now optional. This prevents to copy the product name to sale description as it is now shown on the sale report.
  • In case a different product is shipped to the customer if the invoice method is based on shipment, this shipped product will be used for the invoice. Previously only the initially sold product was always used.
  • Now it is possible to edit the header fields thanks to the new Wizard which takes care of recompute the lines according to the changes.
Sale with modify wizard running
  • Reports on aggregated data has been added to the sale module. The report engine allows to browse the Revenue and Number of sale per:

    • Customer
    • Product
    • Category
    • Country > Subdivision

    Those data are over Period, Company and Warehouse. The reports also show a sparkline for the revenue trend which can be drilled down.

Sales per customer with sparklines Sale revenue per customer graph
  • The sale with the shipment method On Invoice Paid will create the purchase requests and/or drop shipments when the lines are fully paid. Before they were created directly on validation.
  • The shipment cost is not more computed when returning goods.

sale_promotion_coupon

This new module allows to create coupons that are used to apply a promotion on the sale. The coupon can be configured to be usable only a specific number of times globally or per party.

Purchase

  • The product supplier can be used now on the purchase line. This allows to display the supplier definition of this product.
  • Now it is possible to edit the header fields thanks to the new Wizard which takes care of recompute the lines according to the changes.
  • The description on purchase line is now optional. This prevents to copy the product name to purchase description as it now shown on the purchase report. The same change have been applied on purchase requests and requisitions.
  • In case a different product is received from the supplier if the invoice method is based on shipment the received product will be used on the invoice. Previously the purchased product was always used.
  • The user is warned if he tries to confirm a purchase order for a different warehouse than the warehouse of the linked purchase request.

Purchase request quotation

  • This new module allows to manage requests for quotation to different suppliers. Each request will collect quotation information from the supplier. The preferred quotation will be used to create the purchase.

Notification

  • Now it is possible to filter which type of email to use for sending the notification.
  • The email notification skip the recipients if the target field is empty. For example if a notification is defined on the Invoice with the Party as recipient and the Party has not an email address, then the invoice will not be sent. Adding a fallback recipients the email is sent to specific user email which could be a secretary which will be in charge of sending it or a mailbox for a printer which will print it automatically etc.

Tooltips

The following modules have received tooltips:

  • account_credit_limit
  • account_dunning
  • carrier
  • carrier_weight
  • currency
  • product_attribute

Major changes for the developer

  • Starting from this release the tryton client will only support the version 3 of GTK+-3. This will allow to migrate it to Python3.
  • The group widget can be defined as expandable by adding the attribute expandable. If the value is 1, it starts expanded and if the value is 0, it starts unexpanded. Both clients support it.
  • To ensure that all buttons may have their access rights configured a new test has been added. We added also the string, help and confirm attributes to ir.model.button. So they can be shared between different views.
  • The monetary format is now defined on the language instead of the language. According to User Experience best practices the amount should be displayed in the user language format event if it's a foreign currency.
  • It's now possible to manually define an exceptional parent of a language. This allows to use a custom monetary format for each country of the Latin American language.
  • Dict fields are now stored using it's canonical representation. This allows to make equity comparison between them.
  • The language formatting has been simplified to expose the instance methods: format, currency and strftime. A classmethod get is added to return the language instance of the code or the transaction language.
  • The previous API for session management was based on the ORM methods. This makes more complicated to implement alternative session manager. We created a simplified API agnostic to the ORM: new, remove, check and reset.
  • If the database has the required features (for PostgreSQL: the unaccent function), the ilike search will be performed on unaccented strings per default on all Char. This can be deactivated by setting the attribute Char.search_unaccented to False.
  • We have added the support for EXCLUDE constraints. An EXCLUDE constraint is a kind of extension to the UNIQUE constraint which can be applied on a subset of the rows and on expression instead of only columns. For more information, please read the EXCLUDE documentation of PostgreSQL.
  • It is now possible for a module to register classes to the pool only if a specified sets of modules is activated. This replaces the previous silent skip. Existing modules that were relying on the old behaviour must be updated to use the depends keyword otherwise they will crash at start up.
  • Sometimes a module depends optionally on another but it may need to fill from the XML record a value for a field that is defined on the optional module. We added a depends keyword on the field which ignores it if the list of modules is not activated.
  • The clients now support the definition of a specific order and context when searching from a field like Many2One, Reference, One2Many etc. This is useful to have preferred record on top of the list of found records.
  • A new mixin has been added to add logical suppression to a Model. But also we ensure that the client is aware that the model is deactivable. All the modules have been updated to use this new mixin.
  • The context model name is now available on the screen context. This allows for example to change the behaviour of a wizard depending on the context model.
  • Tryton prevents by default to modify records that are part of the setup (which are created by XML file in the modules). This requires to make a query on the ModelData table on each modification or deletion. But usually only a few models have such records, so we now put in memory the list of models that should be checked. This allows to skip the query for most of the models and thus save some queries.
  • Buttons can be defined with PYSON expressions for the invisible or readonly attributes. Some times, the developer wants to be sure that the field used in the PYSON expressions are read by the client. A depends attributes have been added which ensure that the listed fields will be included in all the view where the button is displayed.
  • The administrator can now reset the password of the user with a simple click. The server will generate a random reset password which is available for 1 day by default and send it by email to the user. This reset password is only valid until the user has set a new password. It is also possible to reset this way the admin password using the trytond-admin command line tool.
  • The context has a new optional key _request which contains some information like the remote address, the HTTP host etc. Those values are correctly setup if the server run behind a proxy which set the X-Forwarded headers.
  • A malicious hacker could flood the LoginAttempt table by sending failing request for different logins. Even if the size of the record is limited and the records are purged frequently. The server now limits also the number of attempt per IP network. The size of the network can be configured for each version (IPv4 and IPv6). This are only the last level of protection, it is still recommended to use a proxy and to set up IDS.
  • The name attribute of the tag image can now be a field. In this case, it will display the icon from the value of the field.
  • Now it is possible to extend with the same Mixin all the existing pool objects that are subclasses of a target. An usage example is to extend the Report.convert method of all existing reports to add support for another engine.
  • We have decided to remove the MySQL backend from the core of Tryton. The back-end was not tested on our continuous integration server and so it has many failures like not supporting Python3. The current code has been move to its own repository. This module will not be part of the release process until some volunteer make it green on the test server.
  • The current form buttons are automatically added to the toolbar under the action menu for fast access. Now the developer can define under which toolbar menu the button will appear.
  • Tryton now uses LibreOffice instead of unoconv for converting between report formats. There were some issues with unoconv, which where fixed by using libreoffice directly. Now we publish also docker images with the suffix -office which contains all the requirements for the report conversion.
  • A new Currency.currency_rate_sql method has been added which returns a SQL query that produces for each currency the rate, start_date and end_date. This is useful to get a currency rate in a larger SQL query. This method uses the window functions if available on the database back-end to produce optimized query.
  • Since the introduction of context management in proteus, the client library, the context management was taken from different places in an inconsistent way. We changed the library to always use the context and configuration at the time the instance was created. Some testing scenario may need some adjustment as they could rely on the previous behavior.

Accounting

  • The previous API to reconcile lines allowed only to create one reconciliation at a time. But as this can trigger the processing of the invoice for example, it can be a bottleneck if you are reconciling a lot of different lines like a statement can do. So the API has been improved in the most backward compatible way to allow to create many reconciliation at once.
  • The invoice now has a method to add and remove payments which should always be used.

Web

  • The limit of authentication request per per network is also applied to the web users.
  • Thanks to the implementation of the exclude constraint, the uniqueness of the email of web user only applies to the active users.

Newsletter April 2018

Publié: 2018-04-01 10:00:00+00:00 newsletter

To prepare the coming release 4.8, a lot of pending developments have been finalized before the development freeze. The release 4.8 is scheduled for 23rd April. Until there, we are requesting everyone to help us finding and fixing the remaining bugs. The translation process will start the 2nd April until 20th April at 20:00 CEST. You can contribute your translations on Pootle.

Spring

Erase Party

To help companies to be compliant with the right to erasure from the GDPR, a new wizard to erase a party has been developed. It erase personal information linked to the party like the name, addresses, contact mechanisms etc. It removes also those data from the history tables. But each module adds check to prevent erasure if pending documents for the party still exist.

Match against product category

All the matching criteria against product categories have been unified between all the modules. Any product category will match against itself or any parent category. This is the chosen behavior because it is the less astonishing.

Request depending on shipment method

The sale with the shipment method On Invoice Paid will create the purchase requests and/or drop shipments when the lines are fully paid. Before they were created directly on validation.

Sale reporting

The sale modules receive reports on aggregated data. The report engine allows to browse the Revenue and Number of sale per:

  • Customer
  • Product
  • Category
  • Country > Subdivision

Those data are over Period, Company and Warehouse. The reports also show a sparkline for the revenue trend which can be drilled down.

Purchase request quotation

The new module allows to manage requests for quotation to different suppliers. Each request will collect quotation information from the supplier. The preferred quotation will be used to create the purchase.

Improve reconciliation performance

The previous API to reconcile lines allowed only to create one reconciliation at a time. But as this can trigger the processing of the invoice for example, it can be a bottleneck if you are reconciling a lot of different lines like a statement can do. So the API has been improved in the most backward compatible way to allow to create many reconciliation at once.

Update chart of account

It happens that users need to customize the configuration of the chart of account that comes from a template. Until now, this would prevent any further update without loosing those customization. Now, the records that are synchronised with a template are read-only by default. A check box allows to edit the value and to remove the record from the update process.

Create second chart of account

Sometimes, user may create by mistake a second chart of account. There are very rare case when such creation is valid. As it is a complex task to correct such mistake, we added a warning when creating a second chart of account.

Spanish chart of account

The module, which was published for the first time in the last series 4.6, needs a deep cleaning. The last changes in the accounting modules raised concerns about choices made for this chart. So it was decided to temporary exclude the module from the release process and to not guarantee a migration path.

Import OFX statement

The new module account_statement_ofx implements the import of Open Financial Exchange statement.

Tax report on cash basis

The new module account_tax_cash allows to report taxes based on cash. A tax group to report on cash basis are defined on the Fiscal Year or Period. But they can also be defined on the invoices per supplier.

The implementation of this new module also improved existing modules. The tax lines are verified against modification on closed period. The registration of payment on the invoice is limited to the amount of the invoice.

New tax report definition

Until now, only one tax code was allowed per tax. This was too restrictive. For some country it was needed to create null children taxes to allow more complex reporting. Now, tax codes are no more defined on the tax but instead they contains a list of tax lines. Those lines can define the base or the amount of the tax. On the report, the lines of each tax code are summed per period.

Improve stock location browsing

When there is a very large number of location, the tree Locations Quantity become difficult to use. Especially if you are searching in which location a product is. So we added the option to open this view as a list, this way it is possible to search location by quantity of the product.

Inventory behavior for empty quantity

We found that there are two different expectation from users about the default behavior of the inventory when the quantity is not explicitly set. Some expect that the product quantity should be considered as 0. And others expect that the product quantity is not changed. So we added an option on the inventory to choose the behavior when an inventory line has no quantity.

Assignation in Supplier Shipment Return

Until now, the assignation process was not using children location but this did not work if the location was a view. So now, we assign using the children only if the location is a view.

Support same input and storage location

The supplier shipment support to receive the goods directly in the storage location. This way the invetory steps is skipped.

Create invoice for all sub-projects

Until now, only sub-projects having the same party were invoiced. With issue7096, an invoice for each different party will be created.

Fallback user for email notification

The email notification skip the recipients if the target field is empty. For example if a notification is defined on the Invoice with the Party as recipient and the Party has not an email address, then the invoice will not be sent. By adding a fallback recipients, the email is sent to specific user email which could be a secretary which will be in charge of sending it or a mailbox for a printer which will print it automatically etc.

Limit the expansion of tree

For now, it will no more be possible to expand a node that have too much records. This is needed to prevent to consume all the resources of the client. When such case happen, the client will switch to the form view where normally the children will be displayed in a list view.

Button registration

To ensure that all buttons may have their access rights configured. A new test has been added to ensure that all buttons are registered. We added also the string, help and confirm attributes to ir.model.button. So they can be shared between different views.

Expandable group widget

The group widget can be defined as expandable by adding the attribute expandable. If the value is 1, it starts expanded and if the value is 0, it starts unexpanded. Both clients support it.

Reset changes in pop-up

Until now, when changes on a record from a pop-up window were cancelled, the client reset it using the stored value from the server or delete it if it was not yet stored. Now, the clients will restore the record to the state it had before opening the pop-up.

Stability in rendering of web client

We have pushed many small improvements to sao, the web client, which fixes small jump of elements of the page:

Better keyboard navigation

The buttons of widget are now skipped from tab navigation in sao, the web client. The actions of those buttons are available via keyboard shortcuts.

Position and count on web client

The web client receives finally the label that positions the selected record in the list and shows the number of record in the list.

Editable list view

The management of editable list/tree has been completely reworked. Now the full row become editable on the first click. The focus is kept on the line if it is not valid. The edition is stopped when the user click outside the view.

Tooltips

More modules have been reviewed for tooltips:

Deactivated records

The clients shows next to the search input a toggle button for all model that can be deactivated. This allows the user to make search against deactivated records and to now that such functionality exists.

Simplified API for session management

The previous API was based on the ORM methods. This makes unnecessary more complicated to implement alternative session manager. So we created a simplified API agnostic to the ORM: new, remove, check and reset.

Exclude constraint

We have added the support for *EXCLUDE* constraints. An EXCLUDE constraint is a kind of extension to the UNIQUE constraint which can be applied on a subset of the rows and on expression instead of only columns. For more information, please read the EXCLUDE documentation of PostgreSQL.

This new constraint has been implemented on party category name to ensure that top level (parent IS NULL) names are also unique.

It has also replaced the unique email of web user to only applies to the active user.

Conditional class registration

It is now possible for a module to register class only if a specified sets of modules is activated. This replace the silent skip that existed previously. Existing modules that were using this silent skip must be updated to use the depends keyword otherwise they will fail.

Conditional field in XML

Sometimes a module depends optionally on another but it may need to fill in the XML record a field that is defined on the optional module. We added a depends keyword on the field which makes it ignored if the list of modules is not activated.

Deactivation of records

A new mixin has been added to add logical suppression to a Model. But also we ensure that the client is aware that the model is deactivatable. All the modules have been updated to use this new mixin.

Consistent context usage in proteus

Since the introduction of context management in proteus, the client library, the context management was taken from different places in an inconsistent way. We changed the library to always use the context and configuration at the time the instance was created. Some testing scenario may need some adjustment as they could rely on the previous behavior.

We can see by the number of improvements and issues solved this month that the release 4.8 is approaching quickly,

Ice melting

Icon on tab

Sao, the web client, received the support of icon on tab of the forms. Meanwhile on the desktop client, the same icon on tab has been moved on the left of the label.

Stock quantity per template

The stock quantity was only computed per product because it is the column stored in the stock move. But it may be useful for some cases to compute the stock quantity per template. Indeed products from the same template share the same default unit of measure so their quantities can be summed. So issue7068 added on the products_by_location method the possibility to group by product columns like the template, but also a relate action from the template which show quantity per locations.

Spell checking

The spell checking is now activated on the web client. The spell checking can be activated on any text widget by adding the spell attribute with a PYSON expression that returns the language code.

More protections against flooding

A malicious hacker could flood the LoginAttempt table by sending failing request for different logins. Even if the size of the record is limited and the records are purged frequently. So the server limits the number of attempt also per IP network. The size of the network can be configured for each version (IPv4 and IPv6). This are only the last level of protection, it is still recommended to use a proxy and to set up IDS.

The web_user implement also the same protection.

Reset password

The administrator can now reset the password of the user with a simple click. The server will generate a random reset password which is available for 1 day by default and send it by email to the user. This reset password is only valid until the user has set a new password. It is also possible to reset this way the admin password using the trytond-admin command line tool.

Add cache when checking XML record

Tryton prevents by default to modify records that are part of the setup (which are created by XML file in the modules). This requires to make a query on the ModelData table on each modification or deletion. But usually only a few models have such records, so we could put in memory the list of models that should be checked. So this allows to skip the query for most of the models and thus save some queries.

Add depends on Button

Buttons can be defined with PYSON expressions for the invisible or readonly attributes. Some times, the developer wants to be sure that the field used in the PYSON expressions are read by the client. So a depends attributes have been added which ensure that the listed fields will be included in all the view where the button is displayed.

Remove deprecated feature on GTK+-3

As the desktop client development has switched to GTK+-3. A cleaning of deprecated features has started:

Database connection leak

The PostgreSQL backend uses a pool of connections for performance. During a load test, we has detected a leak of connections from this pool. Some code were not protected by a try/finally to ensure to put always put back the connection used.

A generic contact mechanism retrieval

Similar to the design of the addresses which can be flagged for invoice or delivery usage, the contact mechanism receive the same feature. So the code may now request a contact mechanism of a type and for a specific usage. For example, it is possible now to define which email address of a party should be used to send the invoices. The modules notification_email has been updated to use this method.

FEC export prior to closing fiscal year

It is often requested to be able to export the FEC on a non-closed fiscal year. So the issue5306 make it possible such export. In this case, the generated file will not have an official name as it is still a draft.

Tooltips

More modules have been reviewed for tooltips:

Bug fixes & Improvements

  • issue7085: The unittest for fields have been refactored to follow the best practice: Arrange, Act, Assert.
  • issue7041: The email notification module was putting in the email header the list of blind carbon copied emails.
  • issue7057: The import zip script from the country module is now Python3 compatible.
  • issue7071: Since few releases the date format from the user language was not correctly set and so the client was falling back to the system format. This is now fixed and a common method is used everywhere to ensure coherence.
  • issue7076: All ComboBox has been reviewed to ensure to disable 'scroll-event' and prevent 'move-active' when read-only.
  • issue7087: It prevents to get the same session keys when creating many session with one call. In practice, such call does not exist in standard modules.
  • issue7101: The Promotion registration was missing from the issue6827, this is now fixed. So now the shipment cost is really the unit price when computing the promotion.
  • issue7107: The shipping reference and label were kept when copying packages. But as those values come from the carrier, they should be reset.
  • issue7064: It enforces the consistency for the unit of measure between the display digits and the rounding factor.
  • issue7079: It ensures that all modules requested have been activated by the testing tools. The silent failure was often the source of time lost when writing tests.
  • issue7097: It fixes the string formatting of TrytonException under Python3.
  • issue7092: It improves the performance of Party.address_get by relying on the ORM cache instead of doing a search query. So successive calls to the method will no more perform a query to the database.
  • issue7118: With this change, trytond will not more try to delete translations when a record is deleted if it has not at least one translatable field.
  • issue7104: The shipment cost is improved to not be computed when no goods is shipped. But also in case of return sale, the original shipment cost is not re-computed.
  • issue7112: It prevents to set time converter with a value of zero because the clients do not support such configuration.
  • issue2939: We have closed a pretty old feature request which prevents to close a period if there are still running asset lines.
  • issue6931: The inventory should not remove line for inactive products as there could still be some quantity left in the location.
  • issue7011: The consignment create also invoice line when product are consumed at the production or from the production locations.
  • issue7083: The idempotency key for Stripe payment is always filled. Before it was only set if the checkout process was used.
  • issue7110: The context has a new optional key _request which contains some informations like the remote address, the HTTP host etc. Those values are correctly setup if the server run behind a proxy which set the X-Forwarded headers.
  • issue7022: The invoice lines from backorder are now correctly linked to right stock moves.
  • issue6987: The party required option is hidden for non deferral accounts because they do not support this feature.
  • issue7094: Fix the exception management in the desktop client following the refactoring from issue6907.
  • issue7120: In some cases, the SQLite backend did not create the columns with the right types.
  • issue5182: The usage of chardet to detect the encoding of HTML in the rich text widget was never fully reliable. Now we try common standard encoding and fallback to ASCII.
  • issue7106: The default search on party will now also search on contact mechanism.
  • issue7141: The API of Product.products_by_location and StockMixin._get_quantity have been changed. They no more accept a product_ids argument by only a grouping_filter. The two options were overlapping and creating errors when misused.
  • issue7159, issue7160 and issue7161: They fix the computation of price when the quantity is negative (aka return).

Newsletter February 2018

The is the second monthly news for Tryton. The developers have not been idle during the month of January.

XML Style

The XML style guideline has been updated to remove the constraint of 80 columns. It appeared that this rule did not produce good readable file. Instead we accept to have the opening tag on a single line or one attribute per line.

GIS

A new back-end trytond-gis has been added to support geographic types. It works with PostGIS for now but contribution is welcome to add others like SpatiaLite. The tryton ORM support the fields: GEOMETRY, POINT, LINESTRING, POLYGON, MULTIPOINT, MULTILINESTRING, MULTIPOLYGON and GEOMETRYCOLLECTION; and the operators = and !=. Of course it is possible to write SQL queries that use other geometric operators thanks to the extensibility of python-sql.

Modify Header Wizard

On document like sale, purchase or invoice, there are often constraint that prevent to modify the header once a line has been filled. For example, on the sale it is not allowed to change the currency when there are lines. This is because the unit price computed on the lines depend on the currency selected. But in some cases, the user may really want to change those header fields because he wants to correct a mistake. Now it is possible to edit the header fields thanks to the Modify Header Wizard which takes care of recompute the lines according to the changes.

Post Clearing Moves

A cron task has been added that will post automatically the clearing moves after a delay. The delay is configured on the payment journal.

Stripe Payment

If the customer disputes the payment, a dispute status will be update on the Tryton payment. When the dispute is closed, the payment is updated according if the company win or lose. Some missing charge events has been added. In particular, the refund event which may update the payment amount when it is partial.

New Version Notification

The desktop client has a new option to check if new version for the same series has been published. It takes care of the build for Windows and MacOS.

Register Mixin

A new mechanism has been introduced by issue4735 which allows to extend with the same Mixin all the existing pool objects that are subclasses of a target. A usage example is to extend the Report.convert method of all existing reports to add support for another engine.

Docker Image with libreoffice

Tryton is able to convert the Open Document generated files by the report engine into any format supported by LibreOffice. The default Docker image does not have the requirements for such conversion because it almost triple the size of the image. But now with issue7054, we will publish also images with the suffix -office which contains all the requirements.

Add mnemonic to label of fields

The desktop client had already mnemonic for all button. But with issue2312, they are also added to all field labels. This allow to jumb quickly to any visible field by pressing ALT + <the underlined key>.

Tryton form with mnemonic

Keyword for button

The current form buttons are automatically added to the toolbar under the action menu for fast access. Now with issue7067, the developer can define under which toolbar menu the button will be put. The available options are action, relate or print.

MySQL backend removed

We have decided to remove the MySQL backend from the core of Tryton. The back-end was not tested on our continuous integration server and so it has many failures like not supporting Python3. The current code has been move to its own repository. This module will not be part of the release process until some volunteer make it green on the test server.

Bug fixes & Improvements

  • issue7035: The MacOS X build since the switch to brew contained optimized code for the build machine. Now the build uses non-optimized options.
  • issue6946: The TimeDelta field uses now also the context of the Group of records to format its values. This also applies to the sum on list view.
  • issue7063: It enforces the consistency for the currency between the display digits and the rounding factor.
  • issue7058: The name attribute of the tag image can now be a field. In this case, it will display the icon from the value of the field.
  • issue6400: The currency module receives the tooltips as defined in this task.

As new year resolution, we plan to make a monthly post about what happened in the Tryton project.

A lake covered by snow

TUL2017

The annual Tryton Unconference 2017 took place from the 7th to 10th December at Liège. It started with 2 days of talks and finished with 2 days of code sprint. We also celebrated the 10th anniversary of the project with some drinks and cakes. For those who could not attend, the talks have been registered and the video and slides are available here (note: a technical issue prevented to correctly record the sound the first day but it is still watchable). Some pictures of the events have also been published.

Drop GTK+-2

The desktop client is supporting since one year both version of GTK+ 2 and 3. It is now time to have only GTK+-3 and thus be able to use new features of this version. The build environment for Windows and Mac has been updated to produce builds with the new version of the library.

New Release Process

A discussion started at the #TUL2017 to have longer term release for Tryton. A new process has been discussed which has a majority of positive feedback. So the series ending by 0 (like 5.0) will be supported for 5 years and the others for 1 year. We will keep the rate of one release every 6 month. The new schema will start with the series 5.0 which will be released the 1st October 2018.

Python 3

At the #TUL2017, we discussed about when to drop the support for Python 2 for which upstream support ends in 2020. So we must ensure to stop supporting Python 2 for any series that should still be supported in 2020. The result is that 5.0 will be the first release with only Python 3 support for the server side and also for the desktop client.

Order Line Description

The description of order lines (sale, purchase, invoice etc.) are no more filled automatically. This prevent to duplicate the content from the product form to each lines. But also simplify and speedup the creation of a line from the code. Moreover the product supplier information can be stored on the purchase line. This information can be used on the purchase line instead of the product information. It allows to search per supplier references and to display on the report as description for the line, the reference of the product from the supplier.

Promotion Coupon

This new module allows to create coupon that are used to apply a promotion on the sale. The coupon can be configured to be usable only a specific number of times globally or per party.

PYSON Domain Validation

For PYSON domain, the ORM have the simple strategy to validate records to group them per evaluated domain and then make a search per domain. But it is not optimal when evaluated domains are likely to be unique per record because this generate a search per record. A new case has been added to handle this which searches by grouping multiple domains at once and thus reduce the number of queries.

Dialog Size

Until now, dialog were created with a smaller size than the parent window. But it had the disadvantage to create quickly too small dialog windows. So this behaviour has been changed to use always the same size as the parent.

Query for currency rate

The Tryton design for currency rate is a table with the rate and a date from which the rate applies until another row is added for the currency with a later date. A new method has been added Currency.currency_rate_sql which returns a SQL query that produces for each currency the rate, start_date and end_date. This is useful to get a currency rate in a larger SQL query. This method uses the window functions if available on the database back-end to produce optimized query.

Standalone Lines Workflow

Tryton allows to work with standalone lines instead of pre-generated document to follow the grouping method of external sources. But this requires to have enough origin information to select them. So to improve the workflow the supplier stock moves show the purchase order and the invoice lines show their origin.

Reconcile from Statement

Some users have the workflow to reconcile the lines of the statement they just validated. For this we added a button on statement to launch the reconciliation wizard for the generated account move lines.

Bug fixes & Improvements

  • issue5233: The web client format the numeric values with the user locale but also use an input of type 'number' for editing. This allow to have the right virtual keyboard on mobile.
  • issue6875: The autocompletion was not shown when the user changed existing value in an editable list.
  • issue6978: The inventory lines is now read-only until date and location are filled.
  • issue6132: The user is warned if he tries to confirm a purchase order for a different warehouse than the warehouse of the purchase request.
  • issue7009: Catch all exceptions when evaluating value on pyson widget.
  • issue6934: Search and order translated fields using derivative language.
  • issue6915: Show in reconciliation receivable/payable with negative/positive balance
  • issue7005: Remove definition of rules on user. The group should be the only place where access rights are assigned to the user.
  • issue7014: Use a date instead of a boolean for reconciled field on invoice.
  • issue7013: Use canonical JSON form for Dict value.
  • issue7016: Add relate from drop shipment to sale and purchase.
  • issue7031: Fix missing party name on invoice report on series 4.6.

New Service Company

The company m-ds has joined the [list of companies providing services](/services.html) on Tryton.

Ongoing Works

Wesite Redesign

The Foundation has launch the process of redesigning the website as we reached the financial goal. A company has been hired to make this design but we are looking for your inputs.

New Version Notification

The work has started to provide to the desktop client notification for bug-fix releases. It is important because the desktop client is the only part of the Tryton suite for which the update needs to be managed by the user. And we often see users not updating it and reporting issues which have already been fixed.

Support for geographic objects

An external backend with support of geographic fields is under review. It will support only PostGIS in a first time but maybe SpatiaLite will be added in the future. The backend adds all the standard geometry type of columns and supports the operator = and != in the domain. More operations can be added by using python-sql.

Tryton on Docker

Publié: 2017-11-13 09:00:00+00:00 docker

In order to easy the adoption of Tryton, we are publishing Docker images images on the Docker hub for all series starting from 4.4.

Docker

They contain the server, the web client and all modules of the series. They are periodically updated and tagged per series. They work with the postgres images as default storage back-end.

The usage is pretty simple:

$ docker run --name postgres -e POSTGRES_DB=tryton -d postgres
$ docker run --link postgres:postgres -it tryton/tryton trytond-admin -d tryton --all
$ docker run --name tryton -p 8000:8000 --link postgres:postgres -d tryton/tryton

Then you can connect using: http://localhost:8000/
