Looking more into the problem i noticed that when I do a 'assert
False, self.get_photo_filename()' I get nothing in return. When I do
the same thing (without edit_inline) I get the the filename of the
image.
Does anybody know why when I use edit_inline my
self.get_photo_filename statement from within my Photo save method
doesn't work?
Above is my code
Thanks
