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
Configuration to connect to a sqlite memory database using trytond as module.
>>> config = config.set_trytond('sqlite:///:memory:')
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 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(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
