将其他上下文传递到CBV

我无法将一些其他上下文传递到CBV中。当我将“ userprofile”作为上下文传递时,它阻止了其他任何上下文成功传递到视图中。

我的视图以此开始:

class OrderDetail(LoginRequiredMixin, DetailView):
    model = Order

    def dispatch(self, request, *args, **kwargs):
        try: 
            user_checkout = UserCheckout.objects.get(user=self.request.user)
        except:
            user_checkout = None

        if user_checkout:
            obj = self.get_object()
            if obj.user == user_checkout and user_checkout is not None:  #checks to see if the user on the order instance ties to the user of the current request
                return super(OrderDetail, self).dispatch(request, *args, **kwargs)
            else:
                raise Http404

        else:
            raise Http404

然后我尝试添加此

     def get_context_data(self, *args, **kwargs):
         context = super(OrderDetail, self).get_context_data(*args, **kwargs)            
         userprofile = UserProfile.objects.get(user=self.request.user)
         context["userprofile"] = userprofile 

我没有任何错误。只是页面加载时,不会出现任何应显示的值(基于上下文)。

谢谢!

我认为您需要在return context方法中添加get_context_data

def get_context_data(self, *args, **kwargs):
     context = super(OrderDetail, self).get_context_data(*args, **kwargs)            
     userprofile = UserProfile.objects.get(user=self.request.user)
     context["userprofile"] = userprofile
     return context

此外,由于您的用户个人资料用户模型具有关联(FK或OneToOne),因此您可以像这样简单地访问它们的模板(无需在上下文中传递它):

// If OneToOne
{{ user.userprofile }}

// If FK

{{ user.userprofile_set.first }}  // using reverse relationship to fetch userprofiles
