password_set信号在Django allauth中不起作用

Question

What I am trying to do ?

I am trying to redirect a new user to login dialog after user sets a password for the first time. (I am doing this because the movement user sets a password Django implicitly logout the user)

What is the problem ?

For some reason the password_set signal doesn't seem to work. ie the sender function loginAfterPassChange doesn't get executed.

My Code:

How do I set password

views.py:

@receiver(user_logged_in)
def getFirstTimePass(user, request, **kwargs): #this works
    if user.profile.provider != '' and user.profile.firstTimeLogin:
        user.profile.firstTimeLogin = False
        user.profile.save()
        raise ImmediateHttpResponse(render(request, 'index.html', {'type': user.profile.provider, 'email': user.email}))

@receiver(password_set)
def loginAfterPassChange(request, user, **kwargs): #this doesn't work
    data = {'msg': 'Please login with your new password.'}
    return HttpResponse(data)

def setPassword(request): #this works
    data = {'errMsg': 'Something went wrong.'}
    if not request.user.has_usable_password():
            password = request.POST.get('password')         
            request.user.set_password(password)
            request.user.save()
            data['errMsg'] = ''
    return JsonResponse(data)   

urls.py:

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

urlpatterns = [
url(r'^updatePro', views.setPassword, name='updatePro') 
]

models.py:

class Profile(models.Model):
   user = models.OneToOneField(User, related_name='profile', on_delete=models.CASCADE)  
   provider = models.CharField(max_length=256, default='')
   firstTimeLogin = models.BooleanField(default=True)

if user.profile.provider != '' Check to see if user is logged in with social account or local account.

You can't use a signal for this. Django doesn't do anything with the return value from a signal, so it won't redirect. This simply isn't what signals are for. You should have all this logic in the view.
