Update for Django 1.10+
is_authenticated
is now an attribute in Django 1.10.
if request.user.is_authenticated:
# do something if the user is authenticated
NB: The method was removed in Django 2.0.
For Django 1.9 and older
is_authenticated
is a function. You should call it like
if request.user.is_authenticated():
# do something if the user is authenticated
As Peter Rowell pointed out, what may be tripping you up is that in the default Django template language, you don’t tack on parenthesis to call functions. So you may have seen something like this in template code:
{% if user.is_authenticated %}
However, in Python code, it is indeed a method in the User
class.
