Django REST Framework: Unique_together validation on Serializers -


having issues serializer.is_valid() returning true if serializer instance fails unique_together constraint on model side.

is there way me specify in serializer enforce unique_together constraint?

unfortunately, andreas's answer not quite complete, not work in case of update.

instead, want more like:

def validate(self, attrs):     field1 = attrs.get('field1', self.object.field1)     field2 = attrs.get('field2', self.object.field2)      try:         obj = model.objects.get(field1=field1, field2=field2)     except statewithholdingform.doesnotexist:         return attrs     if self.object , obj.id == self.object.id:         return attrs     else:         raise serializers.validationerror('field1 field2 exists')

this work put, patch, , post.
