I need to check if Model.objects.filter(...) turned up anything, but do not need to insert anything. My code so far is:

user_pass = log_in(request.P

    the boolean value of an empty QuerySet is also False, so you could also just do...

    ...
    if not user_object:
       do insert or whatever etc.
