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.

Thank you very much, Cameron. Definitelly will use it next time. This time I decided to create the separate content type, because seems like I will need to change some methods of it. But I will definitelly use your solution next time ;) -- Best regards, Denis Mishunoff mailto:spliter@sdtcom.lg.ua http://plonetarium.objectis.net
