not sure how reliable this method of fields extraction
There was a problem hiding this comment.
I duobt that this will work when the condition uses a cross-reference between two fields like: Q(first_field__gte=F('second_field')), however I dunno if an unique constraint like that makes sense.
I would like to see also a more complex condition like Q(fielda__isnull=True) | Q(fieldb=False) to be addressed by this validator.
