Django Form初始字典总是空的

Question

views.py

class PlayerListView(PlayerViewMixin, FormMixin, ListView):
    form_class = PlayerFilterForm(initial={'min_rating': 1})
    paginate_by = 50
    template_name = 'players/player_list.html'

    def get_context_data(self, **kwargs):
        context = super(PlayerListView, self).get_context_data()
        context['form'] = self.form_class
        # context['form'].fields['maxrating'].initial = self.request.GET.get('maxrating')
        print(self.get_initial())
        return context

    def get_queryset(self):
        qs = super(PlayerListView, self).get_queryset()
        minrating = self.request.GET.get('minrating')
        maxrating = self.request.GET.get('maxrating')

        if self.request.GET.get('minrating'):
            qs = qs.filter(overall_rating__gte=minrating)

        if self.request.GET.get('maxrating'):
            qs = qs.filter(overall_rating__lte=maxrating)

        return qs

forms.py

class PlayerFilterForm(forms.Form):
    min_rating = forms.ChoiceField(
        initial=1,
        choices=[
            (x, x) for x in range(1, 100)
        ]
    )

...

代码很混乱，此刻只是玩弄。我需要以一种方式来处理我可以在get_initial中执行的动态初始数据，但无论我做什么，我的初始字典总是空的。我错过了一些非常愚蠢的东西吗？
