I'm getting an unexpected validation error in Admin which baffles me.
Any hints appreciated ... here is the traceback
http://dpaste.com/844972/
At the bottom of the traceback where the error is raised, the local vars
are ...
self <django.forms.models.ModelChoiceField object at 0x02414890>
value u'33'
key 'pk'
When I save the item, it auto-generates many-to-many connections to a
few standard images in the database via a through table. However there
is a rule which says "if ever these two images are connected to an item,
only keep this one and drop that one."
I use a post-save signal to "drop that one" using ...
Item_Pictogram.objects.filter(item=instance, pictogram=pic,
via='auto').delete()
The local var value above being u'33' happens to be the exact pk of the
Item_Pictogram record I want to delete - I checked in Postgres.
The pk should be an integer but I suppose that's nothing.
Thanks for any help
Mike
