Dolmen content-type framework

Project description

The package dolmen.content is a convenient way to define content types. Content types usually have several attributes : a type, a schema, an icon. In addition, they need security to control the creation, pages to edit them, easy ways to control the display, and the widgets. This is what provides dolmen.content, with an easy-to-use set of grok directives.


A dolmen.content content is declared as a simple class. Some directives are available to define your content: name, icon, schema and factory. To have detailed information about these directives, please have a look at the package tests.

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)
..."a simple content type")


We now let Grok register our component:

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


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 ...>


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)
>>> my_content.text
