Return to Question

The question is actually two questions asking two very distinct things. I have removed the question which does not relate to the OP question title so the answers make sense and other developers do not get confused as to what is being answered.

I get the following error message -

Exception Value: Cannot assign "(786,)": "Varmst.owner_id" must be a "Owner" instance.

I have the following -

obj.owner_id = Owner.objects.filter(owner_name='Operations'owner_name=owner_obj).values_list('owner_id')[0]

Problem is the value it's returning is a tuple. Specifically this -

(786,)

All I want to return is the integer value or 786.

What am I doing wrong?
