Question

How do I prevent a specific content type from appearing in collections (smart folders) site wide in Plone 3? I’ve looked for relevant options in portal_types and the types and search control panel (turning off the content type for searching doesn’t seem to have an effect on collections).

Specific situation: I recently installed plone.app.discussion on a Plone 3.3.5 installation and now comments appear in all the collections. We want to remove them from the collections.

Thanks.

Portal Types criterion is based on plone.app.vocabularies.ReallyUserFriendlyTypes, a vocabulary factory defined in http://svn.plone.org/svn/plone/plone.app.vocabularies/trunk/plone/app/vocabularies/types.py.

If you patch BAD_TYPES by adding discussion comments you’ll exclude them from Collections, but you’ll also hide them from anywhere this vocabulary factory is used. As far as I know they are also used in contentrules and search control panel.

You can patch BAD_TYPES by adding these lines into __init__.py file of a custom package:

def initialize(context):
"""Initializer called when used as a Zope 2 product."""
    from plone.app.vocabularies import types
    types.BAD_TYPES = types.BAD_TYPES + ('Discussion Item',)
