AnonymousUser.is_authenticated woes

[Stefan Bethke]

First time poster here,

I'm currently working on some unit tests of my Django app, and I'm running into a issue with is_authenticated.

I'm using Django 1.11.16 and Django CMS 3.5.2.

While trying to work with Django CMS menus, I get:

File "/usr/local/lib/python3.6/site-packages/menus/menu_pool.py", line 243, in get_renderer
return MenuRenderer(pool=self, request=request)
File "/usr/local/lib/python3.6/site-packages/menus/menu_pool.py", line 107, in __init__
self.draft_mode_active = use_draft(request)
File "/usr/local/lib/python3.6/site-packages/cms/utils/moderator.py", line 5, in use_draft
is_staff = (request.user.is_authenticated() and request.user.is_staff)
TypeError: 'property' object is not callable

Looking at the documentation, this should be fine. https://docs.djangoproject.com/en/1.11/ref/contrib/auth/#attributes

Trying this in a shell:
./run.sh manage shell
Python 3.6.6 (default, Sep 12 2018, 02:15:29)
[GCC 6.4.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
(InteractiveConsole)
>>> from django.contrib.auth.models import AnonymousUser
>>> AnonymousUser.is_authenticated
<property object at 0x7fb8c93878b8>
>>> bool(AnonymousUser.is_authenticated)
True
>>> AnonymousUser.is_authenticated()
Traceback (most recent call last):
File "<console>", line 1, in <module>
TypeError: 'property' object is not callable

None of that seems right. Have I somehow managed to get something else pulled in?

In the actual application, not-logged in users see the right stuff, so apparently there it's working.

Hi Stefan,

You need to remove the parentheses `()` after `is_authenticated`.

Are you sure you are using Django 1.11?

What does ./run.sh manage --version yields?

User/AnonymousUser was made a property in Django 2.0+ which I assume your version of Django CMS is not compatible with.

Best,

Simon

Django 1.11 correctly returns a callable on AnonymouUser.is_authenticated accesses.

https://github.com/django/django/blob/bd197d3f927f6d17fc4738366126e06c6a95f366/django/contrib/auth/models.py#L448-L450

This was changed in Django 2.0 after a deprecation period of a few releases

https://github.com/django/django/blob/66ac7a129a70a225adc263602bcf7f5750698e8d/django/contrib/auth/models.py#L428-L433

Which is why I suspect you have Django 2.0+ installed.

Cheers,

Simon

The answer is of course to use an instance, not the class:

from django.contrib.auth.models import AnonymousUser
u = AnonymousUser()
u.is_authenticated

CallableBool(False)

u.is_authenticated()

False

bool(u.is_authenticated)

False

Doh!

Sorry for wasting all of yours time.
