Hey,
to a model Event i attach some images. But how can I delete images
from an Event?
If I use something like
http://localhost:8000/moor/admin/doccms/eventimage/2/delete/
manually, the Image's sql entry will be removed, but a Error follows:
AttributeError at /moor/admin/doccms/eventimage/
'NoneType' object has no attribute 'manager'
How can I put a link/buttom for every EventImage on the Event admin
site to remove it's entry?
Thanks, Manuel
