用户注册后Django自动登录（1.4）

Question

我有一个问题，我成功注册用户 - 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。有关为什么用户没有自动登录的想法？

注：

• 用户正在正确注册，他们可以在这个
• 身份验证后登录（** kwargs）将返回正确的用户

• 在settings.py我有：

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

谢谢！

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) 

Answer 1

啊！我想到了。如果任何人有这个问题，如果你手动调用它，从django.contrib.auth导入登录 - 我正在导入视图。注释掉的代码代表了我的情况的不良输入。

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

Answer 2

我做这种方式：

u.backend = "django.contrib.auth.backends.ModelBackend" 
login(request, u) 

Answer 3

这里基于类的观点是，对我工作的代码（Django的1.7）

from django.contrib.auth import authenticate, login 
from django.contrib.auth.forms import UserCreationForm 
from django.views.generic import FormView 

class SignUp(FormView): 
    template_name = 'signup.html' 
    form_class = UserCreationForm 
    success_url='/account' 

    def form_valid(self, form): 
     #save the new user first 
     form.save() 
     #get the username and password 
     username = self.request.POST['username'] 
     password = self.request.POST['password1'] 
     #authenticate user then login 
     user = authenticate(username=username, password=password) 
     login(self.request, user) 
     return super(SignUp, self).form_valid(form)
