We are proud to announce the 3.6 release of Tryton.
The release shows the official support of PyPy which is
an alternative implementation of Python which focuses on speed and efficiency.
As usual, migration from previous series is fully supported with the obvious
exception of the ldap_connection module which was removed.
Major changes for the user
A new color scheme for the graphs has replaced the single brightness
variance. Now the color scheme also changes the hue for each color by the
golden angle (which ensure a color will not be picked twice).
The dictionary widget receive completion on key searching like the other
The date/time widgets have been completely rewritten to be more flexible on
the format to enter. But they are also more practicable when used with mouse
only thanks to the real pop-up for the calendar and the drop down for the
Columns of list view that have always the same value are hidden automatically
because they don't provide information. For example, the list of posted
invoices will not show the state column because by definition they are all
It is now possible to add a description to the cancel move from the wizard.
A new option to only show the balance appears in the General Ledger.
Tax can now be configured to modify the base price for the next taxes in the
It is now possible to define templates for common moves. When running a
template, the user will be asked to encode some data like an amount or a
party, then an account move will be generated with those inputs.
A printable report exists now for the depreciation of assets.
The account charts for France and Belgium has been updated. And the Belgium
one is now translated in dutch.
A test wizard is available now to see the result generated by the payment
term. As the payment terms are quite flexible because they support to apply
many deltas (instead of only one), it is not always easy to forecast the
coverage is now extended to the pain.001.003.03 and 008.003.02 flavors
which are used in Germany. And it is also possible to re-generate a SEPA
message in case of wrong configuration on the first generation.
The statements create moves grouped by default by number, date and party. So
when one statement line is split for invoice reconciliation, only one move
will be created now and the origin of this move will be the group of the
Tax rules can now depend on the origin and the destination country thanks to
the new module account_tax_rule_country.
custom (non-standard) format of SEPA is added by the new module
A new type deposit of account is added by the new module account_deposit.
It allows to invoice deposit and recall later this amount on the next
- The price list can now be defined as tax included. Tryton will then compute
the price without taxes based on the taxes applied.
- A new state won was added to the sale opportunity. It goes to this state
automatically when at least one of its sale is confirmed and all others are
also confirmed or canceled.
- The amount of the opportunity is updated accordantly to the amount of the
linked sales. This will give more accurate reports.
- The computation of the shipment cost is now computed only at the quotation.
This lower the load on the client when the order is pretty large as the cost
will be computed only once instead of each times a line is added.
- The new module sale_extra allow to add extra line on sale based on
criteria. The extra can be either a free product or an extra service cost
- There is now a relate from the product to its order points.
- The creation of purchase request warns also on late production like it does
for late incoming shipment.
- The Shelf Live/Expiration Dates are now supported with the new module
stock_lot_sled. When a lot is expired, it is no more used to compute the
forecast quantity of the stock.
This new area is managed by a set of new commission modules.
The commissions are created for the agent defined on a sale or invoice using a
It is also possible to define principals on the products to which commissions
must be repaid.
Major changes for the developer
- It is now allowed to have many times the same field in list/tree view.
- There is no more a datetime widget for list/tree, two columns with one
widget date and one widget time should be used instead.
- A new field TimeDelta appears in this release to represent a duration. It
replace the float_time widget which had some rounding issue. This new field
is already used in the timesheet and project modules.
- The One2Many widget can be configured to use a Cartesian product with the
selections of many values for Many2One or Reference fields.
- A method restore_history_before is added to ModelSQL which behaves like
the existing restore_history but restore the records just before the
- The on_change methods have been migrated to a behaviour more consistent
with the Active Record Pattern used in Tryton.
Instead of returning a dictionary with the values to change, now the instance
is directly changed. This allow to chain easily the on_change methods or
reuse them in other methods reducing the duplication.
- The method save on ModelStorage is now a dualmethod which means that it
can be called as usual as an instance method but also as a class method with
a list of records. Saving many records at once this way improves the
performance as the method will minimize the number of queries to the database
and will validate the result by bunch.
- The Dict field received a translated method to create descriptors which
translate the values or the keys like the same method on Selection field.
- It is now allowed to use the dotted notation in the order clause of a search.
The ORM will
automatically generate the needed joins.
- The API
of the Report class has been reworked to improve the customization of the
engine. The formatting methods are now more strict to prevent silent failure.
- The safe_eval (which was not sure to be safe) has been completely removed.
In the places where the evaluated code was any way safe, the standard eval
is used. For evaluated code from outside, a JSON notation is now used.
Some utilities have been developed to ease the creation of JSON from XMl or in the views.
- A new kind of button has been added which works on non-saved record. They are
quite similar to on_change but they are triggered by a click on a button
instead of a change of field.
- A new method reverse_compute has been added to Tax which allow to compute
the base amount from the taxed amount.
- The sign of the second currency amount is enforced to be the same as debit -
- The analytic account management has been reworked to use a really One2Many
instead of the pseudo-field. This simplification was possible thanks to the
recent new features like the usage of Reference field on One2Many.
- The vat number is now stored in its compact format.
- The number of decimal for internal price calculations is now a configuration
parameter price_decimal. This parameter is used everywhere to ensure
consistency between all modules.
- Their lines support both mixed invoice type (Invoice vs Credit Note) per line
when computing the invoiced quantity.
- A new state staging is added to the move. Such state doesn't impact at all
the computation of the stock level. It is used for supply on sale, to create
moves in advance.
- Inactive products are still computed for the stock level.
- The computation of assigned move has been improved to take only in
consideration outgoing move assigned not the incoming. This result in a less
optimistic for the stock level and thus prevent to assign a move with an
incoming one that is just assigned but not yet done.
- Forecasts are now automatically deactivated when their period is in the past.
