用户注册后Django自动登录(2.1.4) [英] Django automatic login after user registration (2.1.4)

问题描述

在基于类"的注册视图中，新注册用户的自动登录不起作用.

The automatic login of newly registered users is not working in the case of a "class-based" registration view.

我遵循了本教程中的示例，其中提出了以下建议注册视图:

I followed the example from this tutorial, which proposes the following registration view:

# myapp/views.py
from django.contrib.auth.forms import UserCreationForm
from django.urls import reverse_lazy
from django.views import generic

class SignUp(generic.CreateView):
    form_class = UserCreationForm
    success_url = reverse_lazy('login')
    template_name = 'signup.html'

我尝试包括此答案中的基于类的解决方案，但在成功注册新用户后，登录名却没有不会按预期发生.Django 2.1.4中是否有可能导致此故障的更改?

I tried including the class-based solution from this answer, but after successfully registering a new user, the login doesn't happen as expected. Are there changes in Django 2.1.4 which might cause this to malfunction?

myapp.users.views :

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

class SignUp(generic.CreateView):
    form_class = CustomUserCreationForm
    success_url = '/index'
    template_name = 'signup.html'

    #auto login after register: 
    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=form.cleaned_data['username'], password=form.cleaned_data['password1'],)
        login(self.request, user)
        return super(SignUp, self).form_valid(form)

推荐答案

注册后已通过此行登录

login(self.request, user)

您可能需要重定向主页.所以，您需要更改此行

You may need to redirect homepage. SO, you need to chnage this line

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

到

return HttpResponseRedirect(reverse('url_name'))
