*How* did you try to add it? You show us the error message, but not what
you did to cause it. I don't understand what you are trying to do
(request.POST has nothing to do with URL parsing, so I'm not sure if
you're trying to do something impossible or if that's an unrelated
thing), but showing what you attempted would provide some clues.

It depends upon what you're trying to do. Is it syntactically and
API-wise correct? Looks about right. Will it achieve what you're
wanting? Only you know that, since you haven't explained the problem
you're trying to solve.
Reverse-engineering that little code fragment, it will add constraints
to the queryset so that all returned results must have tags with names
matching each of the names you pass in. If that's the goal, then you've
achieved it.
