django-login-required 中间件给出类型错误

Question

In my django project I am trying to use the django-login-required-middleware . Upon running the server, I get the following error message:

TypeError at /

'bool' object is not callable

Traceback (most recent call last):
  File "/home/krishnan/anaconda3/envs/django_env/lib/python3.8/site-packages/django/core/handlers/exception.py", line 47, in inner
    response = get_response(request)
  File "/home/krishnan/anaconda3/envs/django_env/lib/python3.8/site-packages/login_required/middleware.py", line 26, in __call__
    is_authenticated = request.user.is_authenticated()

Exception Type: TypeError at /
Exception Value: 'bool' object is not callable

When I go to line 26 of the file site_packages/login_required/middleware.py , I see the following code:

# Django v2 now has request.user.is_authenticated as a boolean instead
#       of a function that returns a boolean
if django.VERSION[0] == 2:
    is_authenticated = request.user.is_authenticated
else:
    is_authenticated = request.user.is_authenticated()

I am using Django 3.1.6. I installed the middleware on 04 June 2021 with pip as instructed in the pypi page, and I presume it is the latest version(the middleware.py file does not show version info). As per the pypi page the middleware version is 0.6.1 and supports Django 3.0 also. But from the above code snippet, it would seem that the middleware code checks only for Django version 2 to use the is_authenticated property instead of the is_authenticated() function, and could be the reason for the error. Am I correct? Or could the error be caused by some other reason?

Answer 1

Update the middleware or fix if condition yourself as Django 3 routes you to else which is `is_authenticated()' like 1.11 which fails
