用户注册后Django自动登录（1.4）

我在成功注册用户时遇到问题 - 但是，我希望用户在注册时登录。这是代表我的注册视图的代码。关于用户不自动登录的原因有什么想法吗？

Notes:

• 用户已正确注册，之后即可登录
• authenticate(**kwargs) 返回正确的用户

• 在 settings.py 中我有：

  AUTHENTICATION_BACKENDS = ('django.contrib.auth.backends.ModelBackend',) 
  

Thanks!

def register(request):
    user_creation_form = UserCreationForm(request.POST or None)
    if request.method == 'POST' and user_creation_form.is_valid():
        u_name = user_creation_form.cleaned_data.get('username')
        u_pass = user_creation_form.cleaned_data.get('password2')
        user_creation_form.save()
        print u_name # Prints correct username
        print u_pass # Prints correct password
        user = authenticate(username=u_name,
                            password=u_pass)
        print 'User: ', user # Prints correct user
        login(request, user) # Seems to do nothing
        return HttpResponseRedirect('/book/') # User is not logged in on this page
    c = RequestContext(request, {'form': user_creation_form})
    return render_to_response('register.html', c)

啊!我想到了。如果有人遇到此问题，请从 django.contrib.auth 导入登录名（如果您手动调用它） - 我正在导入视图。注释掉的代码代表了我的情况的错误导入。

# from django.contrib.auth.views import login
from django.contrib.auth import authenticate, logout, login
