Django 如何在 get_context_data 方法中进行交互？

  • 772

告诉我，如何在函数中重定向get_context_data？班级UpdateView

清单：

class UserUpdateView(UpdateView):
    model = User
    fields = [...]
    template_name_suffix = '_update_form'

    def get_context_data(self, **kwargs):
        context = super(UserUpdateView, self).get_context_data(**kwargs)
        if not self.request.user.pk == self.object.pk:
            return redirect('login')
        return context

python

    没门？

    get_context_data返回要在模板中使用的上下文。

    最好覆盖get/post，因为所有必要的数据都在那里。下面是源代码Django

    
class BaseUpdateView(ModelFormMixin, ProcessFormView):
    """
    Base view for updating an existing object.

    Using this base class requires subclassing to provide a response mixin.
    """
    def get(self, request, *args, **kwargs):
        self.object = self.get_object()
        return super().get(request, *args, **kwargs)

    def post(self, request, *args, **kwargs):
        self.object = self.get_object()
        return super().post(request, *args, **kwargs)

    如您所见，您可以编写

    
    def get(self, request, *args, **kwargs):
        self.object = self.get_object()

        if not request.user.pk == self.object.pk:
            return redirect('login')

        return super().get(request, *args, **kwargs)

    一切都会奏效
