python - Django 登录表单/无效用户

Question

我正在学习 Django 并开始构建一个简单的登录表单。当提供经过身份验证的用户名/密码时，我的 View 有效(重定向到“/person/”)。但在提供无效凭据时，它会抛出错误“AnonymousUser”对象没有属性“_meta”。以下是我的观点。

#views.py
def userlogin(request):
    username = request.POST.get('username')
    password = request.POST.get('password')
    user = authenticate(username=username, password=password)
    auth_login(request, user)
    if user is not None:
        if user.is_active:
            print("User is valid, active and authenticated")
            return HttpResponseRedirect('/person')
        else:
            print("The password is valid, but the account has been disabled!")
            # return HttpResponseRedirect('/person/login')
            return render(request, 'login.html')
    else:
        print("The username and password were incorrect.")
        return HttpResponseRedirect('/person/login')

    return render(request, 'login.html')

您正在尝试登录凭据无效的用户 ('AnonymousUser')。

将 auth_login 逻辑移至经过身份验证的用户的 block 中:

user = authenticate(username=username, password=password)
if user is not None:
    if user.is_active:
         auth_login(request, user)
