First off, I am new to both django and python.
I am working on an existing project that is using django-guardian 1.3.2. I verified the server this app is deployed is also using 1.3.2 via pip list.
I am trying to understand the cause of an exception.
There are existing admin.py files, which load just fine.
#!/usr/bin/env python
# coding: utf-8
from guardian.admin import GuardedModelAdmin
from django.contrib import admin
from devices import models
class SomeModelAdmin(GuardedModelAdmin):
pass
admin.site.register(models.SomeModel, SomeModelAdmin)
I added mine, and this also works (on my machine).
#!/usr/bin/env python
# coding: utf-8
from guardian.admin import GuardedModelAdmin
from django.contrib import admin
from common import models
class MyModel1Admin(GuardedModelAdmin):
pass
admin.site.register(models.MyModel1, MyModel1Admin)
class MyModel2Admin(GuardedModelAdmin):
pass
admin.site.register(models.MyModel2, MyModel2Admin)
We deployed the app, and now it fails to start with the following exception:
Traceback (most recent call last): File "/usr/local/share/.virtualenvs/my_app/lib/python2.7/site-packages/django/core/handlers/wsgi.py", line 187, in call self.load_middleware() File "/usr/local/share/.virtualenvs/my_app/lib/python2.7/site-packages/django/core/handlers/base.py", line 47, in load_middleware mw_instance = mw_class() File "/usr/local/share/.virtualenvs/my_app/lib/python2.7/site-packages/django/middleware/locale.py", line 24, in init for url_pattern in get_resolver(None).url_patterns: File "/usr/local/share/.virtualenvs/my_app/lib/python2.7/site-packages/django/core/urlresolvers.py", line 365, in url_patterns patterns = getattr(self.urlconf_module, "urlpatterns", self.urlconf_module) File "/usr/local/share/.virtualenvs/my_app/lib/python2.7/site-packages/django/core/urlresolvers.py", line 360, in urlconf_module self._urlconf_module = import_module(self.urlconf_name) File "/usr/local/share/.virtualenvs/my_app/lib/python2.7/site-packages/django/utils/importlib.py", line 40, in import_module import(name) File "./sites/zpanel/urls.py", line 19, in admin.autodiscover() File "/usr/local/share/.virtualenvs/my_app/lib/python2.7/site-packages/django/contrib/admin/init.py", line 29, in autodiscover import_module('%s.admin' % app) File "/usr/local/share/.virtualenvs/my_app/lib/python2.7/site-packages/django/utils/importlib.py", line 40, in import_module import(name) File "./common/admin.py", line 3, in from guardian.admin import GuardedModelAdmin ImportError: No module named admin
The server is running python 2.7.6, and I am using 2.7.10. I wouldn't think this is an issue since other admin.py files import from guardina.admin just fine.
INSTALLED_APPS = (
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'django.contrib.sites',

As it turns out, there was a directory called guardian in the same directory as my admin.py file. This directory isn't in the source (anymore), nor is it on my local machine. I guess it was some residue from some deployment long ago...
