zope.app.schema 4.0.1

Component Architecture based Vocabulary Registry

This package provides a component architecture based vocabulary registry.

Component-based Vocabulary Registry

This package provides a vocabulary registry for zope.schema, based on the component architecture.

It replaces the zope.schema’s simple vocabulary registry when zope.app.schema package is imported, so it’s done automatically. All we need is provide vocabulary factory utilities:

>>> from zope.component import provideUtility
>>> from zope.schema.interfaces import IVocabularyFactory
>>> from zope.schema.vocabulary import SimpleTerm
>>> from zope.schema.vocabulary import SimpleVocabulary

>>> def SomeVocabulary(context=None):
...     terms = [SimpleTerm(1), SimpleTerm(2)]
...     return SimpleVocabulary(terms)

>>> provideUtility(SomeVocabulary, IVocabularyFactory,
...                name='SomeVocabulary')

Now we can get the vocabulary using standard zope.schema way:

>>> from zope.schema.vocabulary import getVocabularyRegistry
>>> vr = getVocabularyRegistry()
>>> voc = vr.get(None, 'SomeVocabulary')
>>> [term.value for term in voc]
[1, 2]
