[Zope-CMF] Is there a way to change the meta-type of a number of object types

[Norman Khine]

Thanks Tres,
I hope you had a good "break", and seems your in-box is full;^)

Using the external method as described, does it mean, I can modify other
attributes, just by including

 doc = brain.getObject()
       doc.portal_type = 'Card'
---->  doc.review_state = 'published'
       updated.append( doc )

if I want to make all these documents published, for example?

Also, shouldn't portal_type be meta_type, as I am changing the meta_type
from Document to Card?

Regards

Norman

I *think* that what you are looking for is the 'portal_type' attribute;
content objects use that attribute to find their type objects, which then
give them access to the other type-specific policies.  You should be able
to write an ExternalMethod which queries the catalog for the Documents
you would like to make into Cards, and then just set the attribute.

Something like:

   updated = []
   for brain in self.portal_catalog.searchResults( Type='Document'
                                                 # other criteria here
                                                 ):
       doc = brain.getObject()
       doc.portal_type = 'Card'
       updated.append( doc )

   for doc in updated:
       doc.reindexObject()
