I get an AttributeError on deleting an object with a
ManyToManyField('self'). The error is below. My Django is an svn
checkout from yesterday.
I understand that there should be no mediaset_set attribute because the
many-to-many relationship is symmetrical, as documented here:
http://www.djangoproject.com/documentation/model_api/
Is there a bug in the admin interface's delete? Or am I doing
something wrong?
AttributeError at /mtimedia/admin/MediaApp/mediaset/2/delete/
