Periods
|
|
=======
|
|
|
|
.. class:: ActivePeriodMixin
|
|
|
|
This mixin_ makes it easy to create a :class:`~trytond:trytond.model.Model`
|
|
which is active between a start and end date.
|
|
The date range, `Periods <model-account.period>`, or
|
|
`Fiscal Years <model-account.fiscalyear>` that are set in the context are
|
|
used to determine if a particular record should be considered active, or
|
|
not.
|
|
|
|
.. class:: PeriodMixin
|
|
|
|
This mixin_ provides a start and end date to classes that inherit it.
|
|
It also limits any parent or child fields of the class to the same
|
|
`Company <company:model-company.company>` and to dates in the same period.
|
|
|
|
Taxation
|
|
========
|
|
|
|
.. class:: TaxableMixin
|
|
|
|
This is a mixin_ that helps create classes that need to calculate
|
|
`Taxes <model-account.tax>`, tax lines, and tax and base amounts from
|
|
a list of taxable lines.

The *Account Module* includes the `basic universal charts of accounts`_ for
|
|
many languages.
|
|
The :abbr:`XML (eXtensible Markup Language)` files that contain the localised
|
|
charts of account are all generated from the same source XML file.
|
|
The :file:`localize.xsl` :abbr:`XSLT (XML Stylesheet Language Transform)` file
|
|
defines how the source XML file is transformed into a localised chart of
|
|
accounts.
|
|
|
|
To output a localised chart of accounts for language ``<lang>`` run:
|
|
|
|
.. code-block:: bash
|
|
|
|
xsltproc --stringparam lang <lang> localize.xsl account_chart.xml
