"""

Content providers auto-associate with the context object that may be in a

module.

Set up the model object to view::

  >>> root = getRootFolder()

  >>> root['cave'] = cave = Cave()

We also set up another model that the content provider should not be auto-

associated with::

  >>> root['club'] = club = Club()

Let's get a content rpvoider associated with ``cave``::

  >>> from zope.publisher.browser import TestRequest

  >>> request = TestRequest()

  >>> from zope import component

  >>> view = component.getMultiAdapter((cave, request), name='index')

  >>> from zope.contentprovider.interfaces import IContentProvider

  >>> mgr = component.getMultiAdapter((cave, request, view), IContentProvider,

  ...   'manage.cavemen')

We cannot get this content provider for ``club``, as there is none associated

with that as a context for the given name::

  >>> component.queryMultiAdapter((club, request, view), IContentProvider,

  ...   'manage.caveman') is None

  True

Ther is for one with a different name, using an explicit grok.context directive

however:

  >>> mgr = component.getMultiAdapter((club, request, view), IContentProvider,

  ...   'manage.clubmen')
