  • Content->Adapter->View question

    from derek on Mar 30, 2007 12:57 PM 
    If I register an adapter from Folder to a new interface (IFeed) and then
register a view (atom.xml) for the new interface (IFeed), should I be able to
use the atom.xml view on Folder? Or does the interface (IFeed) have to be
directly implemented by Folder for me to use the atom.xml view on the folder?

I'm hoping I can get away with not directly implementing the interface on Folder
using a zcml "interface" tag. I want Zope to simply know that Folder can be
adapter to IFeed and thus can be used for the view. Otherwise, we get into too
much configuration, in my opinion...

THanks,

Derek

I haven't tested it directly in Zope3, but using the approach of base &
fatsyndication, I had to register the views using zcml.

I think that the point is that when finding a view, Zope3 tries to find
an adapter for the context (IFolder) and request (IRequest?), but never
tries to "do magic" and try each adapter was registered for IFolder and
find then the view.
