I'm having a silly issue with the admin interface and an ImageField in
one of my models. A simple model I have contains an ImageField, and
many objects of this model are related to some other model (Project,
not shown). I can add/view images just fine, but when I try to delete
an image, I get a value error saying:
"ValueError at /admin/projects/project/1/
The 'image' attribute has no file associated with it."
The entry correctly deletes from my DB (on successive loads of the
admin page, I no longer see the entry), the file does not delete from
my directory however, and this error pops up. Any thoughts on why?
I have tried with & without my custom delete function, with the same
results. Help would be appreciated, thanks.
