使用Django createview创建相关对象

Question

嘿，我正在使用Django 1.10.7

我正在创建一个表单，用于创建商店的商店位置。 现在，我想做的是在加载表单时使商店已经与商店位置相关联。

网址具有商店外键的正确ID，例如：localhost：8000 // office / dealer / 1 / location / create。 并且我发现store密钥在request关键字参数中。 但是我不知道如何将其关联到表单中。 任何帮助将非常感激

这是我的代码

#views.py

class DealerLocationCreateView(CreateView):
    model = models.DealerLocation
    fields = ['dealer'
     'dealer_location_name',
     'dealer_location_mailing_address',
     'dealer_location_mailing_city',
     'dealer_location_mailing_state',
     'dealer_location_mailing_zipcode',
     'dealer_location_mailing_phone',
     'dealer_location_shipping_address',
     'dealer_location_shipping_city',
     'dealer_location_shipping_state',
     'dealer_location_shipping_zipcode',
     'dealer_location_shipping_phone'
     ]

    def form_valid(self, form):
        form.instance.dealer = self.request.dealer_pk
        return super(DealerLocationCreateView, self).form_valid(form)

# urls.py
url(r'^dealer/(?P<dealer_pk>\d+)/location/create', DealerLocationCreateView.as_view(), name='new-location'),

为什么不使用：

def form_valid(self, form):
    pk = self.kwargs.get("dealer_pk", None)
    form.instance.dealer = pk
    return super(DealerLocationCreateView, self).form_valid(form)
