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()
