将身份验证装饰器添加到基于类的视图中

Question

您好，我试图将身份验证装饰器应用于基于类的视图，但它们似乎不起作用，因为当我查看模板时，我没有被重定向到默认帐户/登录/下一个？网址

from .forms import TodoForm
from .models import Todo
from django.template import loader
from django.contrib.auth.decorators import login_required
from django.utils.decorators import method_decorator


from django.views.generic import (
    CreateView,
    ListView,
    DetailView,
    UpdateView,
    DeleteView
)
from django.urls import reverse
from django.shortcuts import render, get_object_or_404


# Create your views here.
@method_decorator(login_required, name='dispatch')
class TodoListView(ListView):
    template_name = 'ToDo/todo_list.html'
    queryset = Todo.objects.all()

@method_decorator(login_required, name='dispatch')
class TodoDetailView(DeleteView):
    template_name = 'ToDo/todo_detail.html'
    queryset = Todo.objects.all()

    def get_object(self):
        id_ = self.kwargs.get("id")
        return get_object_or_404(Todo, id=id_)

您不能将 django auth 装饰器用于 CBV（基于类的视图）。您可以使用 mixins 来实现这一点。例如，代替 login_required 装饰器，您可以将 LoginRequiredMixin 用于 CBV，

from django.contrib.auth.mixins import LoginRequiredMixin

class MyView(LoginRequiredMixin, View):

    login_url = '/login/'
    redirect_field_name = 'redirect_to'

查看文档https://docs.djangoproject.com/en/3.0/topics/auth/default/#the-loginrequired-mixin
