This needs to be a standard filter expression. So you use the normal Django query filter syntax as documented here: http://docs.djangoproject.com/en/1.1/topics/db/queries/#retrieving-specific-objects-with-filters Don't forget these are *parameters to a function*, not expressions in themselves. So in your case you need: return super(GevondenManager,self).get_query_set().exclude(crcWaarde=0) -- DR. -- You received this message because you are subscribed to the Google Groups "Django users" group.
