Django 注销问题

Question

我正在开发一个推文应用程序，虽然我可以在身份验证过程中登录，但我的注销功能不起作用。我将我的源代码留给解释。我等待你的帮助

我得到的错误如下： (http://127.0.0.1:8000/logout/?next=/) 我得到此网站无法访问错误！ 更准确地说，我无法访问我想要的页面。当我点击注销时，我必须退出该帐户。 我还应该提到我正在使用 Python 3.12.0 和 Django。

我的网址.py

    from django.contrib import admin
    from django.urls import path, include 

    urlpatterns = [
        path('admin/', admin.site.urls),
        path("",include('tweetapp.urls')),
        path("",include('django.contrib.auth.urls')),]

我的观点.py

from django.shortcuts import render, redirect
from . import models
from django.urls import reverse
from tweetapp.forms import AddTweetForm, AddTweetModelForm

def listtweet(request):
    all_tweets = models.Tweet.objects.all()
    tweet_dict = {"tweets":all_tweets}
    return render(request,'tweetapp/listtweet.html',context=tweet_dict)

def addtweet(request):
    if request.POST:
        nickname = request.POST["nickname"]
        message = request.POST["message"]
        models.Tweet.objects.create(nickname=nickname, message=message)
        return redirect(reverse('tweetapp:listtweet'))
    else:
        return render(request,'tweetapp/addtweet.html')
    
def addtweetbyform(request):
    if request.method == "POST":
        form = AddTweetForm(request.POST) 
        if form.is_valid():
            nickname = form.cleaned_data["nickname_input"]
            message = form.cleaned_data["message_input"]
            models.Tweet.objects.create(nickname=nickname, message=message
                                        )
            return redirect(reverse('tweetapp:listtweet'))
        else:
            print("error in form")
            return render(request,'tweetapp/addtweetbyform.html', context={"form":form})
    else:
        form = AddTweetForm()
        return render(request,'tweetapp/addtweetbyform.html', context={"form":form})

def addtweetbymodelform(request):
    if request.method == "POST":
        form = AddTweetModelForm(request.POST) 
        if form.is_valid():
            print(form.cleaned_data)
            return redirect(reverse('tweetapp:listtweet'))
        else:
            print("error in form")
            return render(request,'tweetapp/addtweetbymodelform.html', context={"form":form})
    else:
        form = AddTweetModelForm()
        return render(request,'tweetapp/addtweetbymodelform.html', context={"form":form})
    ```


and i share my base.html 

          <li class="nav-item">
            <a class="nav-link" href="{% url 'login' %}">Login</a>
          </li>
          <li class="nav-item">
            <a class="nav-link" href="{% url 'logout' %}?next=/">Logout</a> 
          </li>

Answer 1

在您的

urls.py

中，您有两条“”路线。那是

path("",include('tweetapp.urls'))

和

path("",include('django.contrib.auth.urls'))

您需要将帐户管理更改为类似这样的

urlpatterns = [
    path("accounts/", include("django.contrib.auth.urls")),
]

参考Django的文档

Answer 2

您必须设置 root 才能注销。它对我有用。

为此，请将其添加到您的 urls.py 文件中：

from django.contrib.auth import views as auth_views

urlpatterns = [
    path('admin/', admin.site.urls),
    path("",include('tweetapp.urls')),
    path("",include('django.contrib.auth.urls')),
    path("logout/", auth_views.LogoutView.as_view(next_page=<redirect page>)),]
