Django signals for login and registration

Question

I need to check information in user and request models while user logging in, so I've wrote this code using django signals:

from django.contrib.auth.signals import user_logged_in

def on_login(sender, user, request, **kwargs):
    ...

user_logged_in.connect(on_login)

How can I have access to the request while user registering? I've wrote this code, so I have access to user model, but not to request:

from django.db.models.signals import post_save

def on_registration(sender, user, created, **kwargs):
    if created:
        ...

post_save.connect(on_registration, sender=settings.AUTH_USER_MODEL, dispatch_uid="create_user_profile")

Can I do that without using 3-rd party applications?

写一个装饰器并应用到您的函数中。然后，您可以在执行视图之前或之后注入您想要的任何代码。您也可以避免使用信号和第三方应用程序。
