plone.multilingual

This package contains the core functionality for the next generation multilingual engine for Plone.

These are the main artifacts and its purposes:

canonical:

• the canonical organizes the information about a “translation-group”

• it’s using a dictionary with language-codes as keys and uuids (provided by plone.uuid) as values

storage:

• persistent storage, which holds the canonicals in an IOBTree

• the OOBTree’s key is the UUID of the content, the according value is the canonical

manager:

• adapter for ITranslatable

• provides the translations API

adapters:

• ITranslationLocator - where to put a translation

• ITranslationIdChooser - generates a valid id for a translation

• ITranslationCloner - copy the language-independent content to the translation

• ITranslationFactory - creates the translation

In order to have a test we have a type called Demo that has an adapter called DemoLanguage that will allow to get the language of the object:

>>> from plone.multilingual.interfaces import ITranslationManager
>>> from plone.multilingual.interfaces import ILanguage
>>> from plone.app.testing import setRoles, login, TEST_USER_ID, TEST_USER_NAME

>>> portal = layer['portal']
>>> setRoles(portal, TEST_USER_ID, ['Manager'])
>>> login(portal, TEST_USER_NAME)
>>> portal.invokeFactory('Folder', 'ob1', title=u"An archetypes based folder")
'ob1'

>>> ILanguage(portal['ob1']).set_language('ca')

Ensuring that the new object gets its UUID:

>>> from plone.uuid.interfaces import IUUID
>>> ob1_uuid = IUUID(portal['ob1'])
>>> isinstance(ob1_uuid, str)
True

We create a new translation in ‘en’ language:

>>> ITranslationManager(portal['ob1']).add_translation('en')

We try to create a new translation in ‘ca’ that already exists:

>>> ITranslationManager(portal['ob1']).add_translation('ca')
Traceback (most recent call last):
...
KeyError: 'Translation already exists'

We try to create a new translation without language:

>>> ITranslationManager(portal['ob1']).add_translation(None)
Traceback (most recent call last):
...
KeyError: 'There is no target language'

We get the ‘en’ translation:

>>> ITranslationManager(portal['ob1']).get_translation('en')
<ATFolder at /plone/ob1-en>
>>> ILanguage(ITranslationManager(portal['ob1']).get_translation('en')).get_language() == 'en'
True

let’s get all the translations:

>>> ITranslationManager(portal['ob1']).get_translations()
{'ca': <ATFolder at /plone/ob1>, 'en': <ATFolder at /plone/ob1-en>}

let’s get only the languages:

>>> ITranslationManager(portal['ob1']).get_translated_languages()
['ca', 'en']

has_translation:

>>> ITranslationManager(portal['ob1']).has_translation('en')
True

>>> ITranslationManager(portal['ob1']).has_translation('it')
False

register_translation with invalid language:

>>> ITranslationManager(portal['ob1']).remove_translation('en')
>>> ITranslationManager(portal['ob1']).register_translation('', portal['ob1-en'])
Traceback (most recent call last):
...
KeyError: 'There is no target language'

register a translation with content:

>>> ITranslationManager(portal['ob1']).register_translation('en', portal['ob1-en'])
>>> ITranslationManager(portal['ob1']).get_translations()
{'ca': <ATFolder at /plone/ob1>, 'en': <ATFolder at /plone/ob1-en>}

changing the content-language (there should act a subscriber):

>>> ILanguage(portal['ob1-en']).set_language('it')
>>> from zope.event import notify
>>> from zope.lifecycleevent import ObjectModifiedEvent
>>> notify(ObjectModifiedEvent(portal['ob1-en']))
>>> ITranslationManager(portal['ob1']).get_translations()
{'ca': <ATFolder at /plone/ob1>, 'it': <ATFolder at /plone/ob1-en>}

test the delete-subscriber:

>>> from OFS.event import ObjectWillBeRemovedEvent
>>> notify(ObjectWillBeRemovedEvent(ITranslationManager(portal['ob1']).get_translation('it')))
>>> ITranslationManager(portal['ob1']).get_translations()
{'ca': <ATFolder at /plone/ob1>}

>>> from plone.multilingual.interfaces import ITranslationIdChooser
>>> chooser = ITranslationIdChooser(portal['ob1-en'])
>>> chooser(portal, 'es')
'ob1-es'

>>> ITranslationManager(portal['ob1']).add_translation('es')
>>> child_id = portal.ob1.invokeFactory('Folder', 'ob1_child', language="ca")

>>> from plone.multilingual.interfaces import ITranslationLocator
>>> locator = ITranslationLocator(portal['ob1-en'])
>>> locator('es') == portal
True

>>> child_locator = ITranslationLocator(portal.ob1.ob1_child)
>>> child_locator('es') == portal['ob1-es']
True

>>> ITranslationManager(portal['ob1']).remove_translation('es')

>>> from plone.multilingual.upgrades.to02 import upgrade

>>> from plone.multilingual.upgrades.to03 import upgrade

>>> from plone.multilingual.interfaces import IMultilingualStorage
>>> gsm = portal.getSiteManager()
>>> gsm.queryUtility(IMultilingualStorage) is None
True
