Newsgroups: gmane.comp.python.announce

Hi,

We are happy to announce the 2.6 release of Tryton.

What is Tryton
==============

Tryton is a three-tiers high level general purpose application
platform using either PostgreSQL, MySQL or SQLite as database engine.

The core of Tryton (also called Tryton kernel) provides all the
necessary functionalities for a complete application framework: data
persistence, extensive modularity, users management (authentication,
fine grained control for data access, handling of concurrent access of
resources), workflow and report engines, web services and
internationalisation. Thus constituting a complete application platform
which can be used for any relevant purpose.

What's new
==========

This release brings major changes in the API with the introduction of the
Active Record pattern. But also the graphical user interface was not left
without improvements. And as usual there are many bugfixes, module
improvements and new modules (as announced in the previous release news).
Of course, migration from previous series is fully supported.


Major changes in graphical user interface
-----------------------------------------

* Management of model access and create/delete field access.
  The client is now aware of the model access which allows the disable
buttons
  when the user doesn't have access to it.
  It is also possible to manage the create/delete event on fields in
addition
  to read/write.

* Dynamic size limit on the One2Many, Many2Many and Char
  It is now possible to limit the size of those fields and the client will
  enforce it.

* Remove "Please wait" box. The popup was annoying because it make the
client
  lost the focus.

* Paste in editable list view. It is possible to paste from a spreadsheet
to
  update a set of rows.

Major changes on the server side
--------------------------------

* Allow to use Reference field in One2Many & Many2Many.
  In addition to the Many2One, the reverse field could be a Reference
field.
  In the future, the link between Move and Shipments will be done like that
  instead of having 4 exclusive Many2One fields.

* All kind of buttons have been merge into one simple concept.

* Active Record: This is the result of refactoring work started 2 years
ago.
  Here are some benefits:

    * Reduce the amount of code (about 2.2k lines removed) for example
      on_change_with and getter of Function field can be merged.

    * Unify access to the value of record if it is stored or not in the
      database. It allows to remove of values dictionary on on_change
method.

    * Remove loop over ids in getter of Function field:

        before:

                def getter(self, ids, name):
                    res = {}
                    for record in self.browse(ids):
                        res[record.id] = ...
                    return res

        now:

                def getter(self, name):
                    return self....

    * Rationale the register process of Model (use copy of fields etc.)

    * Remove session in wizard. Now the wizard instance is the session.

* Allow to store the views in a XML file instead of the database. This
supports
  the modification of a view without updating the database. A good speedup
for
  designing views.

* A new kind of validation has been added the pre_validation. The new
  'pre_validation' allows to validate a record without saving it. This is
used
  by the client to validate lines of a One2Many. With 'pre_validation' it
is
  possible to provide feedback to the user as soon as possible and before
the
  record is saved.

Modules
-------

account
~~~~~~~

* The Trial Balance report displays now the start and end balance in
addition
  to the debit and credit columns.

* Double-clicking on Balance Sheet opens accounts.

* The Account Chart doesn't show cumulate Debit/Credit by default but only
for
  the current period.

* The Aged Balance is computed over all fiscalyears.

* The Account Moves have been refactored to include an origin field which
  allows to easily link it to the master document. They have two number
fields
  for draft and posted.

account_stock_continental
~~~~~~~~~~~~~~~~~~~~~~~~~

* Updating cost price create automaticaly a stock accounting move.

purchase
~~~~~~~~

* The purchase manages negative quantities on lines, they will generate
Return
  Shipments and Credit Note.

stock
~~~~~

* A graph has been added showing the evolution in past and future of the
stock
  level for a product per warehouse.

New modules
-----------

* stock_lot defines lot of products.
* stock_split adds a wizard to split move.
* account_fr adds French account chart.
* production defines the basics for production management.
* stock_supply_production adds automatic supply mechanisms via production
  requests.

Other changes graphical user interface
--------------------------------------

* Constant interpolation has been added to line graph.
* The group could have a readonly state.
* It is possible to define a time format different of the classic
'%H:%M:%S'.

Other changes on server side
----------------------------

* The ModelSQL.default_sequence has been removed. The sequence fields will
no
  more increase indefinitely.
* The time format is validated, so it is possible to enforce the second to
0
  for example.
* __tryton__.py is replaced by tryton.cfg, a static file.
* It is possible to use tuple as Reference value. It is usefull to
construct
  dynamic domain on such field in PYSON.
