django-tenants：登录后重定向到租户 url 引发“NoReverseMatch：‘demo.localhost’不是已注册的命名空间”

Question

我似乎找不到解决用户身份验证时发生的错误的方法。

用户需要在公共网站级别登录，比方说localhost/login ，当他/她通过身份验证时，我需要将用户重定向到相应的子域，例如demo.localhost 。 到目前为止，这对我不起作用，即使在检查了一些有关该主题的帖子之后也是如此。

这是用户登录的customers.views中的 views.py：

def login_view(request):
    if request.method == 'POST':
        form = AuthenticationForm(request,data=request.POST)
        print("form login view")
        if form.is_valid():
            print("checkpoint")
            username = form.cleaned_data.get('username')
            password = form.cleaned_data.get('password')
            user = authenticate(username=username, password=password)

            user = form.get_user()
            schema_name = user.schema_name

            print(user)
            if user is not None:
                login(request, user)
                url = reverse(schema_name + '.localhost:8000/mydashboard/')
                print("url")
                return HttpResponseRedirect(url)
    else:
        print("not working")
        form = AuthenticationForm()

    context = {
        'form': form,
                }
    return render(request, 'login.html', context)

这是核心文件夹中的网址：

urlpatterns = [
    path('admin/', admin.site.urls),
    path('django_plotly_dash/', include('django_plotly_dash.urls')),
    path('mydashboard/', include('mydashboard.urls',namespace="mydashboard")),
    
]

我在mydashboard.urls中添加了app_name = 'mydashboard'

这是我不断收到的错误的回溯：

Internal Server Error: /registration/loginUser
Traceback (most recent call last):
  File "/Users/pierre/opt/anaconda3/lib/python3.9/site-packages/django/urls/base.py", line 71, in reverse
    extra, resolver = resolver.namespace_dict[ns]
KeyError: 'demo.localhost'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):

    raise NoReverseMatch("%s is not a registered namespace" % key)
django.urls.exceptions.NoReverseMatch: 'demo.localhost' is not a registered namespace

更新：删除reverse并包含在 url 中的request.scheme 。

def login_view(request):
    if request.method == 'POST':
        form = AuthenticationForm(request,data=request.POST)
        print("form login view")
        if form.is_valid():
            print("checkpoint")
            username = form.cleaned_data.get('username')
            password = form.cleaned_data.get('password')
            user = authenticate(username=username, password=password)

            user = form.get_user()
            schema_name = user.schema_name

            print(user)
            if user is not None:
                login(request, user)
                print(request.scheme)
                url = request.scheme + '://' + schema_name + '.localhost:8000/mydashboard/'
                print("url",url)
                return HttpResponseRedirect(url)
    else:
        print("not working")
        form = AuthenticationForm()

    context = {
        'form': form,
                }
    return render(request, 'login.html', context)

这仍然有效，output 出现以下错误：

                response = get_response(request) …

Unsafe redirect to URL with protocol 'localhost'
Bad Request: /mydashboard/simulations_list
HTTP GET /mydashboard/simulations_list 400 [0.09, 127.0.0.1:50218]

这很奇怪，因为请求的 url 可以正常工作 url，在登录后尝试重定向到它之前已注册并且可以毫无问题地访问

编辑#2：

发现上面的代码在目标 url 不需要login required有效

# this does not work 
@login_required
def simulationslistView(request,):
     return render(request, 'simulations_list.html')

# this works
def simulationslistView(request,):
     return render(request, 'simulations_list.html')

我显然确保该应用程序是安全的，并且只能由登录用户访问。 是否有解决方法来确保它有效？

Answer 1

reverse是一个内部 django 实用程序到 go，从“应用程序名称”+“：”+“url 友好名称”到“真实 url”。 在您的示例中，您已经提供了“真实网址”。

在你领先的时候退出，然后做：

            if user is not None:
                login(request, user)
                url = request.scheme + '://' + schema_name + '.localhost:8000/mydashboard/'
                print("url")
                return HttpResponseRedirect(url)

• 注意没有reverse
• 注意添加 URL 方案（http/https 由最初发出请求的方式决定）
