django 不重定向到下一页需要登录

问题描述 投票：0回答：1

我有多个视图函数，在我的 view.py 中有 

@login_required
装饰器。当我注销并尝试访问其视图功能具有 
@login_required
装饰器的页面之一时，我被重定向到具有这种 url 的页面。 
http://localhost:8002/signin/?next=/pending/
。但是，当我登录时，我被重定向到索引页面而不是待定页面，我已经尝试使用 this question 和 this question 的解决方案来解决我的问题，但它不起作用。

这是我的登录视图函数

def signin(request):
    if request.user.is_authenticated:
        return redirect(index)
    if request.method == "POST":
        form = Signin(request.POST)
        if form.is_valid():
            username = request.POST.get("username")
            password = request.POST.get("password")

            user = User.objects.filter(username=username.lower()).exists()
            if user:
                get_user = User.objects.filter(username=username.lower())
                check_pass = check_password(password, get_user[0].password)
                if not check_pass:
                    messages.error(request, "Invalid Credentials")
                    return redirect(signin)
                else:
                    login(request, get_user[0])
                    return redirect(index)
            else:
                messages.error(request, "Invalid Credentials")
                return redirect(signin)
    else:
        form = Signin()
        return render(request, "accounts/login.html", {"form": form})

这是我的 urls.py

from django.urls import path

from accounts import views


urlpatterns = [
    path("signup/", views.signup, name="signup"),
    path("signin/", views.signin, name="signin"),
    path("signout/", views.signout, name="signout"),

这是我的登录模板

那么我该怎么做才能将我重定向到下一页而不是索引页。

这不是您验证用户和重定向的正确方式。成功登录后，您已重定向到索引页面。要重定向到下一页，您可以尝试：

redirect_url = request.GET.get('next')
return redirect(redirect_url)

signin 视图应该是这样的： 从 django.contrib.auth 导入验证

def signin(request):
    if request.user.is_authenticated:
        return redirect(index)
    if request.method == "POST":
        form = Signin(request.POST)
        if form.is_valid():
            username = request.POST.get("username")
            password = request.POST.get("password")
            redirect_url = request.GET.get("next")

            user = authenticate(username=username, password=password)
            if user is not None:
                if user.is_active:
                    login(request, user)
                    messages.success(request, "You have logged in!")
                    
                    if redirect_url:
                        return redirect(redirect_url)
                    else:
                        return redirect('index')
                else:
                    messages.warning(request, "Your account is disabled!")
            else:
                messages.error(request, "Invalid Credentials")
    else:
        form = Signin()
    
    return render(request, "accounts/login.html", {"form": form})

或者你可以使用 Django 内置的 LoginView。在你的 urls.py 中导入 LoginView 并添加到这样的路径：

from django.contrib.auth.views import LoginView

urlpatterns = [
    # Other urls
    path('login/', LoginView.as_view(template_name='accounts/login.html'), name='signin'),
]

LoginView 的 Django 官方文档。 检查文件
