Adds a keyword widget (similar to to Archetypes.Widget:KeywordWidget) to z3cform.

Project Description

Introduction

This product adds a Keyword widget (similar to Archetypes.Widget:KeywordWidget) for plone.z3cform.

How To Use (Doc Tests):

>>> from z3c.form import testing
>>> testing.setupFormDefaults()
>>> import zope.interface
>>> import zope.schema
>>> from zope.schema.fieldproperty import FieldProperty

Use the Keywords field your field type:

>>> from collective.z3cform.keywordwidget.field import Keywords
>>> class IFoo(zope.interface.Interface):
...
...     keywords = Keywords(title=u'Keywords')
>>> class Foo(object):
...     zope.interface.implements(IFoo)
...     keywords = FieldProperty(IFoo['keywords'])
...
...     def __init__(self, keywords):
...             self.keywords = keywords
...
...     def __repr__(self):
...             return '<%s %r>' % (self.__class__.__name__, self.name)

We need to make sure that the keywords property is indexed in portal_catalog.

First, we write the indexer. The indexer is a special adapter that adapts the type of an object and provides the value of the attribute to be indexed.

>>> from plone.indexer.decorator import indexer
>>> @indexer(IFoo)
... def keywords(obj):
...     return IFoo(obj).keywords

We need to register our indexer as a named adapter, where the name corresponds to the index name. In ZCML, that may be:

<adapter name="keywords" factory=".indexers.keywords" />

For testing purpoese, we will register it directly.

>>> from zope.component import provideAdapter
>>> provideAdapter(keywords, name='keywords')

Now we add a form in which the widget will be rendered:

Specify the KeywordWidget factory (‘KeywordFieldWidget’) as the field’s widgetFactory.

>>> from z3c.form.testing import TestRequest
>>> from z3c.form import form, field
>>> from collective.z3cform.keywordwidget.widget import KeywordFieldWidget
>>> class FooAddForm(form.AddForm):
...
...     fields = field.Fields(IFoo)
...     fields['keywords'].widgetFactory = KeywordFieldWidget
...
...     def create(self, data):
...             return Foo(**data)
...
...     def add(self, object):
...             self.context[object.id] = object
...
...     def nextURL(self):
...             return 'index.hml'

Create, update and render the form:

>>> root = app
>>> request = TestRequest()
>>> addForm = FooAddForm(root, request)
>>> addForm.update()
>>> print addForm.render()
