Question

嗨，我正在尝试将身份验证修饰符应用于基于类的视图，但它们似乎无法正常工作，因为当我查看模板时，我没有重定向到默认帐户/登录名/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_)

您不能为CBV（基于类的视图）使用django auth装饰器。您可以使用mixins实现此目的。例如，您可以将LoginRequiredMixin用作CBV，而不是login_required装饰器，

from django.contrib.auth.mixins import LoginRequiredMixin

class MyView(LoginRequiredMixin, View):

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

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

向基于类的视图添加身份验证装饰器
