The is the second monthly news for Tryton. The developers have not been idle during the month of January.
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.
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.
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.
A cron task has been added that will post automatically the clearing moves after a delay. The delay is configured on the payment journal.
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.
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.
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.
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.
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>.
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.
As new year resolution, we plan to make a monthly post about what happened in the Tryton project.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
The company m-ds has joined the [list of companies providing services](/services.html) on Tryton.
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.
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.
The first day, 7th December 2017, is dedicated to business oriented talks.
The second day, 8th December 2017, is focused on developer talks.
And don't forget to spread the word! #TUL2017
The 2017 foundation board renewal process has finished. We are happy to anounce that the new board is composed by:
- Axel Braun from Germany
- Jonathan Levy from the United States of America
- Korbinian Preisler from Germany
- Nicolas Évrard from Belgium
- Pedro Luciano Rossi from Argentina
- Sebastián Marró from Argentina
- Sergi Almacellas Abellana from Spain
Congratulations to Nicolas Évrard as he became the second president of the Tryton foundation board.
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.
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/
We are proud to announce the 4.6 release of Tryton.
This release is enhanced by the addition of 9 new modules covering many different topics. There has been also an effort in improving the graphical user interface and the user experience by fixing many small details. It is also good to note the inclusion of the Spanish charts of accounts which required some improvements in the standard accounting modules. Of course it includes many bug fixes and performance improvements.
As usual the migration from previous series is fully supported. Some manual operation may be required, see migration from 4.4 to 4.6.
In addition to the user name, company and currency in the title of the clients, we have added the profile or the login details. This way, the user can find faster the right windows.
The order of the toolbar has been reworked to have a more logical order and grouping. The same logical has been applied also on the toolbars of the widgets.
On previous version, the headers of the column were always centered. Now they use the same alignment as the content following the best practice. Texts columns aligned on left and numerical columns on right. Also to improve the discoverability, editable lists have a grid design instead of just stripped row. This allows the user to know directly if it is editable.
Similar to the redesign of the button on relation field in the release 4.2, this release improves the design of the Binary and Image widget. Only the available buttons are shown instead of being disabled. But also before having the option to upload a new file, the previous file must be cleared. This prevents confusion to some users.
A new wizard has been added to renew the fiscal year. It takes the previous fiscal year and some other parameters to create the new fiscal year automatically. The sequences can be reset automatically and the same number of periods are created.
On some countries, it is required to add a legal notice when some taxes are applied. This legal notice can now be configured on the tax to be included automatically and so avoid mistakes or oversights.
The tax rule system is the way Tryton configure the taxes to apply on an invoice for a party. This works by replacing the default tax by the one defined on the matching rule. Now it is possible to configure the rule to keep the default tax and add the rule one. It is needed to support tax mechanism from some countries like the equivalence surcharge for Spanish VAT.
The tax description which appear on the invoice is now translatable.
The payable and receivable accounts on party are no more required. This prevented the creation of parties when no default values was setup even if the values were not needed. Now, a message will be raised only when the value is needed for a particular operation.
It is now possible to search the amounts of the general legder. It is useful for example to get only the accounts with a balance.
The general ledger and the income statement can be computed for a range of date in addition to the sets of periods.
The configuration wizard allows to configure default receivable and payable accounts for categories and products.
This is a new module that aims to implement common accounting requirements in Europe. The first common feature added is the EC sales list.
A new module registers two default charts of account and taxes for Spain:
The clearing of payments only worked when paying a specific line. Now it can also work if an account is defined instead of a line. The common case is when you register a deposit for which you have no line but still want to register it once the payment is succeeded.
The manage of payment with Stripe received many improvements:
- The user can now create manually Stripe payments. Usage showed that it may be needed and there was indeed no technical reason to prevent.
- It is possible to select the specific Source of the Customer.
- It is now possible to enter an existing Customer by filling its ID.
- Tryton supports now the two steps payment flows. It is just checkbox to uncheck to activate on this flow. The amount can be changed between the authorisation and the capture and the capture is just triggered by a button.
This new module allows to define for a dunning procedure level to send an email to the party. The template of the email can be different at each level. The action of sending an email is logged into the system.
This new module allows to manage consignment stock from supplier in the company warehouse and at the customer warehouse. The corresponding invoices are created automatically when products are used from such location.
This new module allows to define some storage location as movable. They can be moved by an internal shipment. This can be used for example to manage palettes.
This new module allows to register payments on sale before the creation of any invoice. When the payments for full amount of the sale are authorized, the sale is automatically confirmed. For example, this module is used to manage payment from a e-commerce website.
This new module adds under and over shipment tolerance on the sale. If the quantity of a sale line is under shipped but inside the tolerance percentage, then the line will be considered as fully shipped and no back-order will be created. If the quantity of a sale line is over shipped more than the tolerance percentage, then a warning is raised.
This new module adds the generic feature to send email to parties or users of document based on trigger conditions. The email can embed as attachment any report of the document. A common usage for this module is to send automatically the invoice to the customer when it is posted.
From the 7th to 10th of December, the annual Tryton Unconference will come back to its birthplace: Liège. The conference happens later than usual to occur during the 10th anniversary of the first commit.
This will be the seventh edition. Users, developers and interested people will have the opportunity to discover or talk about Tryton.
The two first days will be the proper unconference. A first part will be dedicated to business oriented talks and a second part focused on developer talks. Talks can be submitted at firstname.lastname@example.org.
Informations and registration are available at https://tul2017.tryton.org/.
If you want to request a talk on a specific topic, you can send your request to the Tryton mailing list. If you have question about the organisation, please contact the foundation at email@example.com.
And don't forget to spread the word! #TUL2017
