Your queryset is a set of Candidate objects and that model indeed does
not have a field called users_owner. Do you just mean "owner" perhaps?
Since you don't explain what you're hoping to see, it's tough to guess
the right answer here, but the error message is telling you the problem.
You are trying to order by a field that doesn't exist. "users_owner"
would make sense if you were working with a User model, but not on a
Candidate model.
Perhaps you are misunderstanding the use of related_name? What is the
problem you are trying to solve. In other words, what are you trying to
order the candidates by?
