用戶註冊後Django自動登錄（1.4）

Question

我有一個問題，我成功註冊用戶 - 但是，我希望用戶在註冊時登錄。這是代表我的註冊視圖的代碼。有關爲什麼用戶沒有自動登錄的想法？

注：

• 用戶正在正確註冊，他們可以在這個
• 身份驗證後登錄（** kwargs）將返回正確的用戶

• 在settings.py我有：

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

謝謝！

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。如果任何人有這個問題，如果你手動調用它，從django.contrib.auth導入登錄 - 我正在導入視圖。註釋掉的代碼代表了我的情況的不良輸入。

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

Answer 2

我做這種方式：

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

Answer 3

這裏基於類的觀點是，對我工作的代碼（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)
