Question

我正在尝试使子窗体在子视图中工作，但是无法使其工作。这主要是继承问题，我尝试了标准的Python方式，但仍然遇到这个问题。错误在底部。

Link代表我要继承的BasketLineForm。

我继承的表单：

from oscar.apps.basket.forms import BasketLineForm as CoreBasketLineForm

class AddBattery(CoreBasketLineForm):
    class Meta(CoreBasketForm.Meta):
          model=Battery
          fields = ('battery_manufacturer', 'battery_capacity', 'battery_warranty')

Link for我从以下网站继承的BasketView：

我继承的视图：

from oscar.apps.basket.views import BasketView as CoreBasketView

class BasketView(CoreBasketView):

    def get_formset_kwargs(self):
        kwargs = super(BasketView, self).get_formset_kwargs()
        kwargs['strategy'] = self.request.strategy
        kwargs['battery']=self.request.modify
        return kwargs


    def get_queryset(self):
        return self.request.basket.all_lines()
    def get_battery_form(self):
        return AddBattery()
    def get_battery_objects(self):
        return Battery.objects.all()

    def get_context_data(self, **kwargs):
        context = super(BasketView, self).get_context_data(**kwargs)
        context['battery_form'] = AddBattery(self.request.POST)
        context['battery_data'] = self.get_battery_objects()
        return context

    def get_success_url(self):
        return safe_referrer(self.request, 'basket:summary')

错误：

Request Method: | GET

在第69行上：

def get_context_data(self, **kwargs):
    context = super(BasketView, self).get_context_data(**kwargs)
    context['battery_form'] = AddBattery() #this is line 69
    context['battery_data'] = self.get_battery_objects()
    print(context)
    return context

Django SubForm没有在Django子视图中出现扭曲
