===============================================================
loops - Linked Objects for Organization and Processing Services
===============================================================
($Id$)
Let's do some basic set up
>>> from zope.app.testing.setup import placefulSetUp, placefulTearDown
>>> site = placefulSetUp(True)
>>> from zope import component, interface
and setup a simple loops site with a concept manager and some concepts
(with all the type machinery, what in real life is done via standard
ZCML setup):
>>> from loops.interfaces import ILoops, IConcept
>>> from loops.concept import Concept
>>> from loops.setup import ISetupManager
>>> from loops.knowledge.setup import SetupManager
>>> component.provideAdapter(SetupManager, (ILoops,), ISetupManager,
... name='knowledge')
>>> from loops.tests.setup import TestSite
>>> t = TestSite(site)
>>> concepts, resources, views = t.setup()
>>> loopsRoot = site['loops']
>>> from loops.knowledge.knowledge import Topic
>>> component.provideAdapter(Topic)
For testing and demonstration purposes let's create a topic.
>>> topic = concepts['topic']
>>> topic01 = concepts['topic01'] = Concept(u'loops for Zope 3')
>>> topic01.conceptType = topic
Content Internationalization
============================
Let's look at a certain concept that should contain i18n-alized data.
>>> topic01.title
u'loops for Zope 3'
We can query the available languages, the current language setting and
the default language using a LanguageInfo object that is similar to a view.
>>> from zope.publisher.browser import TestRequest
>>> from loops.i18n.browser import LanguageInfo
>>> langInfo = LanguageInfo(topic01, TestRequest())
>>> langInfo.availableLanguages
[]
>>> langInfo.language is None
True
>>> langInfo.defaultLanguage is None
True
In order to use content i18n we have to define the available languages
as an option on the loops root object.
>>> loopsRoot.options = ['languages:en,de,it']
>>> langInfo = LanguageInfo(topic01, TestRequest())
>>> langInfo.availableLanguages
['en', 'de', 'it']
>>> langInfo.defaultLanguage
'en'
>>> langInfo.language
'en'
By setting an appropriate value in the URI we can select a certaing
language for processing of the current request.
>>> input = {'loops.language': 'it'}
>>> langInfo = LanguageInfo(topic01, TestRequest(form=input))
>>> langInfo.availableLanguages
['en', 'de', 'it']
>>> langInfo.defaultLanguage
'en'
>>> langInfo.language
'it'
Let's now use a form to edit an i18n-sensible attribute. For this we have
to set up some components needed by the zope.formlib machinery.
>>> from zope.publisher.interfaces.browser import IBrowserRequest
>>> from zope.app.form.browser import TextWidget, ChoiceInputWidget, DropdownWidget
>>> from zope.schema.interfaces import ITextLine, IText, IChoice
>>> from zope.app.form.interfaces import IInputWidget
>>> component.provideAdapter(TextWidget, (IText, IBrowserRequest),
... IInputWidget)
>>> from loops.concept import ConceptTypeSourceList
>>> from zope.schema.vocabulary import getVocabularyRegistry
>>> getVocabularyRegistry().register('loops.conceptTypeSource', ConceptTypeSourceList)
>>> component.provideAdapter(ChoiceInputWidget,
... (IChoice, IBrowserRequest), IInputWidget)
>>> component.provideAdapter(DropdownWidget,
... (IChoice, ConceptTypeSourceList, IBrowserRequest), IInputWidget)
We also have to mark the attributes that should be stored in multiple
languages on the type object.
>>> from loops.common import adapted
>>> tTopic = adapted(topic)
>>> tTopic.options = ['i18nattributes:title,description']
Now we are ready to enter a language-specific title.
>>> from loops.browser.concept import ConceptEditForm
>>> input = {'form.title': 'loops per Zope 3', 'loops.language': 'it',
... 'form.actions.apply': 'Change'}
>>> form = ConceptEditForm(topic01, TestRequest(form=input))
>>> form.update()
>>> topic01.title
{'it': u'loops per Zope 3'}
