dolmen.content 0.2.2

Defining the content

Let’s demonstrate the package’s features with a simple and non-exhaustive test:

>>> import dolmen.content
>>> from zope import schema

>>> class IContentSchema(dolmen.content.IBaseContent):
...    text = schema.Text(title=u"A body text", default=u"N/A")

>>> class MyContent(dolmen.content.Content):
...  """A very simple content
...  """
...  dolmen.content.schema(IContentSchema)
...  dolmen.content.name("a simple content type")

Grokking

We now let Grok register our component:

>>> import grok
>>> grok.testing.grok_component('mycontent', MyContent)
True

Factory

When the content is registered, a factory is registered, using the full module and class dotted names. It allows us to query and instanciate the content easily:

>>> from zope.component import getUtility
>>> factory = getUtility(dolmen.content.IFactory,
...                      name="dolmen.content.MyContent")
>>> factory
<dolmen.content.factoring.Factory object at ...>

Schema

The content can now be instanciated. As we can see here, the object is effectively providing the schema:

>>> my_content = factory()

>>> my_content.__content_type__
'a simple content type'

>>> IContentSchema.providedBy(my_content)
True
>>> my_content.text
u'N/A'
