I have a problem with my product.
I use Zope 2.7.5 and Plone 2.0.5.
I need to create the copy of Document content-type on my product's
install the same way as it is done in portal_types via
"Factory-based Type Information" option of dropdown.
I just need to have the copy of it and to alter some fields.
Here's some code I stole from Chapter 8 of my book, were a
Folder-derived type is created in an install script::
from Products.CMFCore.Expression import Expression
# Customize types
types_tool=getToolByName(portal,'portal_types')
# New 'NewsFolder' type based on folder
types_tool.manage_addTypeInformation(id='NewsFolder',
add_meta_type="Factory-based Type Information",
typeinfo_name="CMFPlone: Plone Folder")
nf = getattr(types_tool, 'NewsFolder')
nf.manage_changeProperties(filter_content_types=1,
allowed_content_types=('News Item',))
actions=nf._cloneActions()
for a in actions:
if a.id == 'view':
a.action = Expression('string:${object_url}/newsfolder_view')
nf._actions=(actions)
After a clone of the type is made based on Plone Folder, some changes
are made: contents are filtered, and only News Items are allowed; also
an action is changed to point to a custom template.
This is a better option than using the copy/paste API like you might do
in the ZMI.
