Library to access Tryton server as a client

Project description

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

Example of usage

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


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')])
>>> Wizard('ir.module.activate_upgrade').execute('upgrade')

Creating a party

First instantiate a new Party:

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

Fill the fields:

>>> = 'ham'

Save the instance into the server:

>>> > 0

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.lang.code

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 ='42')
>>> party.addresses #doctest: +ELLIPSIS

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()
>>> = 'spam'

Append it to categories of the party

>>> party.categories.append(category)
>>> party.categories #doctest: +ELLIPSIS

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 ='69')
>>> address ='23')

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.addresses == reversed_addresses

Setting context

Make French translatable:

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

Create a category in English:

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

Translate in French:

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

Read in English:

>>> category.reload()

Read in French:

>>> category_fr.reload()
