Как решить list indices must be integers or slices, not str?

Question

[Глеб]

Мне выскакивает ошибка list indices must be integers or slices, not str в get_form UpdateView на эту строку:

self.fields['category'] = Category.objects.all().filter(user=self.request.user)

Как её решить?

Вод код самого класса:

class HomeUpdateView(UpdateView):
    model = Model
    fields = ['title',  'category']
    success_url = '/account/home'
    template_name = 'main/update/update_home.html'

    def get_form(self, form_class=None):
        self.fields['category'].queryset = Category.objects.all().filter(user=self.request.user)
