I did the following to obtain all container-like Dexterity content
types on a project I'm working on.
However, reading through this thread I realized I can improve it to be
more bullet proof. More specifically: I should test for IFolderish
implementation rather than inheritance from the Container class. Maybe
someday I'll do that :)
# Code begin
from Products.CMFCore.utils import getToolByName
from Products.CMFPlone.InterfaceTool import getDottedName
from plone.dexterity.content import Container
from plone.dexterity.interfaces import IDexterityFTI
from plone.dexterity.utils import resolveDottedName
from zope.app.component.hooks import getSite
def get_ftis():
"""
Return a sequence of `IDexterityFTI` corresponding to all
Dexterity content types on
the portal.
"""
portal = getSite()
portal_types = getToolByName(portal, 'portal_types')
return [fti for fti in portal_types.listTypeInfo() if
IDexterityFTI.providedBy(fti)]
def is_container_type(fti):
"""
Retorna `True` se e somente se o `IDexterityFTI` fornecido
representa um tipo que é um
container.
"""
klass = resolveDottedName(fti.klass)
return issubclass(klass, Container)
def get_container_ftis():
"""
Return a sequence of `IDexterityFTI` corresponding to all
Dexterity content types on
the portal which are container-like.
"""
return [fti for fti in get_ftis() if is_container_type(fti)]
# Code end
