Autodiscovering does not work

[gagarski]

Hello!
I am using django 1.7 and trying to enable autodiscovering of rules.py files as it shown in the README file:

INSTALLED_APPS = (
    # ...
    'rules',
    'rules.apps.AutodiscoverRulesConfig',
)

But I am getting the following error:

Traceback (most recent call last):
  File "./manage.py", line 10, in <module>
    execute_from_command_line(sys.argv)
  File "/usr/lib/python3.4/site-packages/django/core/management/__init__.py", line 385, in execute_from_command_line
    utility.execute()
  File "/usr/lib/python3.4/site-packages/django/core/management/__init__.py", line 354, in execute
    django.setup()
  File "/usr/lib/python3.4/site-packages/django/__init__.py", line 21, in setup
    apps.populate(settings.INSTALLED_APPS)
  File "/usr/lib/python3.4/site-packages/django/apps/registry.py", line 89, in populate
    "duplicates: %s" % app_config.label)
django.core.exceptions.ImproperlyConfigured: Application labels aren't unique, duplicates: rules

When I am disabling rules application:

INSTALLED_APPS = (
    # ...
    #'rules',
    'rules.apps.AutodiscoverRulesConfig',
)

I am getting another error (when I am trying to load any page):

ImportError at /
No module named 'rules.apps.AutodiscoverRulesConfig'; 'rules.apps' is not a package
Request Method: GET

Exception Location: /usr/lib/python3.4/site-packages/authority/__init__.py in autodiscover, line 21

What is the correct way of using autodiscover?

[dfunckt]

You don't need both 'rules' and 'rules.apps.AutodiscoverRules' in INSTALLED_APPS. In fact you mustn't -- that's what the first error tells you (django.core.exceptions.ImproperlyConfigured: Application labels aren't unique, duplicates: rules)

I see the exception location is in "django-authority", can you please remove it from INSTALLED_APPS and see if the error goes away?

Either way, please paste the whole traceback.

I hadn't authority app installed, but I forgot to remove its import from project's urls.py.
Yes, it seems to be a problem with django-authority, which does not work with django 1.7. Thanks a lot.

Traceback, as you have asked for.
