login(request, user, backend=None) [source]
To log a user in, from a view, use login(). It takes an HttpRequest object and a User object. login() saves the user’s ID in the session, using Django’s session framework.
Note that any data set during the anonymous session is retained in the session after a user logs in.
This example shows how you might use both authenticate() and login():
from django.contrib.auth import authenticate, login
def my_view(request):
username = request.POST['username']
password = request.POST['password']
user = authenticate(username=username, password=password)
if user is not None:
login(request, user)
# Redirect to a success page.
...
else:
# Return an 'invalid login' error message.
...
Changed in Django 1.10:
In older versions, when you’re manually logging a user in, you must successfully authenticate the user with authenticate() before you call login(). Now you can set the backend using the new backend argument.
Please login to continue.
