There's a way to do what you want to do, but I don't remember out of the top of my head. I can check it out on the week, but you'll need to customize some things on the Producer's ModelAdmin, not just set the list of inlines, because, as it was said, inlines are for "children" objects (i.e. other objects that have a FK pointing to self, not the other way around).
I don't remember exactly, but IIRC it went about making a single-form inline_formset and possibly some modifying of the model-specific admin template. Or maybe making a custom ModelForm in the ModelAdmin's get_form method On Sun, Feb 17, 2013 at 3:14 PM, Peter of the Norse <[email protected]> wrote: > Have you tried using unique_together?
