======================= Tryton Scripting Client

A library to access Tryton's models like a client.

Example of usage

>>> from proteus import config, Model, Wizard, Report

Configuration

Configuration to connect to a sqlite memory database using trytond as module.

    >>> config = config.set_trytond('sqlite:///:memory:')

There is also the ``config.set_xmlrpc`` method which can be used to connect
using a URL, and the ``config.set_xmlrpc_session`` method (when used as a
context manager) which connects for a session.

Activating a module

Find the module, call the activate button and run the upgrade wizard.

>>> Module = Model.get('ir.module')
>>> party_module, = Module.find([('name', '=', 'party')])
>>> party_module.click('activate')
>>> Wizard('ir.module.activate_upgrade').execute('upgrade')

Creating a party

First instantiate a new Party:

    >>> Party = Model.get('party.party')
    >>> party = Party()
    >>> party.id < 0
    True

Fill the fields:

    >>> party.name = 'ham'

Save the instance into the server:

    >>> party.save()
    >>> party.name
    'ham'
    >>> party.id > 0
    True

Setting the language of the party

The language on party is a Many2One relation field. So it requires to get a Model instance as value.

>>> Lang = Model.get('ir.lang')
>>> en, = Lang.find([('code', '=', 'en')])
>>> party.lang = en
>>> party.save()
>>> party.lang.code
'en'

Creating an address for the party

Addresses are store on party with a ``One2Many`` field.
So the new address just needs to be appended to the list ``addresses``.

    >>> address = party.addresses.new(postal_code='42')
    >>> party.save()
    >>> party.addresses #doctest: +ELLIPSIS
    [proteus.Model.get('party.address')(...)]

Adding category to the party
~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Categories are linked to party with a ``Many2Many`` field.

So first create a category

    >>> Category = Model.get('party.category')
    >>> category = Category()
    >>> category.name = 'spam'
    >>> category.save()

Append it to categories of the party

    >>> party.categories.append(category)
    >>> party.save()
    >>> party.categories #doctest: +ELLIPSIS
    [proteus.Model.get('party.category')(...)]

Print party label
~~~~~~~~~~~~~~~~~

There is a label report on ``Party``.

    >>> label = Report('party.label')

The report is executed with a list of records and some extra data.

    >>> type_, data, print_, name = label.execute([party], {})

Sorting addresses and register order

Addresses are ordered by sequence which means they can be stored following a specific order. The set_sequence method stores the current order.

>>> address = party.addresses.new(postal_code='69')
>>> party.save()
>>> address = party.addresses.new(postal_code='23')
>>> party.save()

Now changing the order.

>>> reversed_addresses = list(reversed(party.addresses))
>>> while party.addresses:
...     _ = party.addresses.pop()
>>> party.addresses.extend(reversed_addresses)
>>> party.addresses.set_sequence()
>>> party.save()
>>> party.addresses == reversed_addresses
True

Setting context

Make French translatable:

    >>> Language = Model.get('ir.lang')
    >>> french, = Language.find([('code', '=', 'fr')])
    >>> french.translatable = True
    >>> french.save()

Create a category in English:

    >>> Category = Model.get('party.category')
    >>> with config.set_context(language='en'):
    ...     category = Category(name="Category")
    ...     category.save()

Translate in French:

    >>> with config.set_context(language='fr'):
    ...     category_fr = Category(category.id)
    ...     category_fr.name = "Categorie"
    ...     category_fr.save()

Read in English:

    >>> category.reload()
    >>> category.name
    'Category'

Read in French:

    >>> category_fr.reload()
    >>> category_fr.name
    'Categorie'
