Django CBV登录并将用户重定向到个人资料页面：将用户名传递给LOGIN_REDIRECT_URL

Question

Django 1.10 Python 3.5.3

使用CBV，我可以将用户登录到该站点。但是，登录后我无法让用户重定向到他们的个人资料。我希望他们在登录后转到此页面：https://example.com/profiles/user。相反，我得到了这个错误：

class Profile(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    bio = models.TextField(max_length=500, blank=True)
    location = models.CharField(max_length=30, blank=True)
    birth_date = models.DateField(null=True, blank=True)
    username = models.CharField(max_length=30,
                                unique = True,
                                default='')
    email = models.EmailField(default='',
                                unique = True,
                                max_length=100)
    profile_image = models.ForeignKey(Image, null=True)
    slug = models.SlugField(default='')
    is_active = models.BooleanField(default=True)
    is_authenticated = models.BooleanField(default=True)
    is_anonymous = models.BooleanField(default=False)

    USERNAME_FIELD = 'email'
    REQUIRED_FIELDS = ['name']

    @receiver(post_save, sender=User)
    def create_user_profile(sender, instance, created, **kwargs):
        if created:
            Profile.objects.create(user=instance)

    @receiver(post_save, sender=User)
    def save_user_profile(sender, instance, **kwargs):
        instance.profile.save()

    def next_birthday(born):
        today = date.today()

        return today.year - born.year - ((today.month, today.day) < (born.month, born.day))

    def get_absolute_url(self):
        return reverse('profiles:profile', kwargs={'slug': self.slug})

    def __str__(self):
        return self.username

如何将用户名传递给网址？

models.py

class LoginView(FormView):

    template_name = 'registration/login.html'

    """
    Provides the ability to login as a user with a username and password
    """
    success_url = 'profile/<slug>'
    form_class = AuthenticationForm
    redirect_field_name = REDIRECT_FIELD_NAME

    @method_decorator(sensitive_post_parameters('password'))
    @method_decorator(csrf_protect)
    @method_decorator(never_cache)

    def dispatch(self, request, *args, **kwargs):
        # Sets a test cookie to make sure the user has cookies enabled  
        request.session.set_test_cookie()

        return super(LoginView, self).dispatch(request, *args, **kwargs)

    def form_valid(self, form):
        auth_login(self.request, form.get_user())

        # If the test cookie worked, go ahead and
        # delete it since its no longer needed
        if self.request.session.test_cookie_worked():
            self.request.session.delete_test_cookie()

        return super(LoginView, self).form_valid(form)

    def get_success_url(self):  
        redirect_to = self.request.GET.get(self.redirect_field_name)
        if not is_safe_url(url=redirect_to, host=self.request.get_host()):
            redirect_to = self.success_url

        return redirect_to

views.py

urlpatterns = [
    url(r'^(?P<slug>[\w-]+)/$',
        ProfileView.as_view(),
        name = 'profile'),

urls.py

LOGIN_REDIRECT_URL = 'profiles:profile'

settings.py

class Program
  {
    static void Main(string[] args)
    {
      string srcfile = @"C:\Workspace\tmp\TestSTuff\bank\transactions.txt";
      string transactionstr;

      using (FileStream fs = new FileStream(srcfile, FileMode.Open, FileAccess.Read))
      {
        byte[] buffer = new byte[fs.Length];
        int numtoread = (int)fs.Length;
        int numread = 0;
        while (numtoread > 0)
        {
          int n = fs.Read(buffer, numread, numtoread);
          if (n == 0)
            break;
          numread += n;
          numtoread -= n;
        }
        transactionstr = Encoding.Default.GetString(buffer); 
      }

      char[] newline = { '\r','\n' };
      char delim = ',';
      string[] transactionstrs = transactionstr.Split(newline);

      List<Transaction> transactions = new List<Transaction>();
      foreach (var t in transactionstrs)
      {
        try
        {
          string[] fields = t.Split(delim);
          DateTime.Parse(fields[1]);
          transactions.Add(new Transaction
          {
            AccountNumber = int.Parse(fields[0]),
            TransactionDate = DateTime.Parse(fields[1]),
            TransactionAmount = double.Parse(fields[2])
          });
        }
        catch
        {
          continue;
        }
      }
    }
  }

  public class Transaction
  {
    public int AccountNumber { get; set; }
    public DateTime TransactionDate { get; set; }
    public double TransactionAmount { get; set; }
  }

提前致谢。

尝试在您的

中使用此功能

settings.py

LOGIN_REDIRECT_URL = '/accounts/home_page/<username>/'

urls.py

from .views import *
from . import views
from django.conf import settings
from django.conf.urls import url

urlpatterns = [
    url(r'^accounts/home_page/(?P<username>[\w-]+)/$', UserProfileView.as_view(), name='user_profile_view'),
]

的观点

class UserProfileView(View):
    @method_decorator(login_required)
    def get(self, request, username):
        if request.user.username == username:
            profile = get_object_or_404(User, user=request.user)
            return render(request, 'registration/home.html', {'profile': profile})
        else:
            raise Http404

警告：如果对于我仍在处理的用户没有临时页面，它可能会给您404错误...
