I\'ve been trying to solve this problem for a couple of days now, getting quite desperate. See the commented out code snippets for some of the things I\'ve tried but didn\'t wor
Category.objects.filter(user=request.user)

Try instead
Category.objects.get(user=request.user)
or
Category.objects.filter(user=request.user)[0]
