proteus 5.4.2

Library to access Tryton server as a 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:')

Installing 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 instanciate 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(zip='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(zip='69')
>>> party.save()
>>> address = party.addresses.new(zip='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
