“ImportError: No module named urls” occurs in Django admin

Question

Django: 1.3.5
nginx: 1.2.6
uwsgi: 1.0.5

My django app runs on nginx and uwsgi. When opening admin page, 500 Error occured. This error is "ImportError: No module named urls".

Running the command "python manage.py runserver" and opening admin page, then 500 error didn't occured.

commenting admin on urls.py, then error doesnt occur.

This error only occurs on nginx and uwsgi.

How could I fix it?

urls.py

from django.conf.urls.defaults import *
from django.conf import settings
from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
                       (r'^blog/', include('myApp.blog.urls')),
                       (r'^admin/', include(admin.site.urls))
                       )

wsgi.py

import os
import sys
import site

reload(sys)
sys.setdefaultencoding('utf-8')
sys.path.append('/path/to/myApp/')

site.addsitedir('/usr/lib/python2.6/site-packages')
os.environ['DJANGO_SETTINGS_MODULE'] = 'myApp.settings'

import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()

ImportError: No module named urls

settings.py (INSTALLED_APPS)

ROOT_URLCONF = 'myApp.urls'
INSTALLED_APPS = (
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.sites',
    'django.contrib.admin',
    'django.contrib.sitemaps',
    'django.contrib.markup',
    'myApp.blog',
)

Open a python shell and type this : from django.conf.urls.defaults import * if it cannot import and show you error so the urls package in not installed but if the python shell can import perhaps you have a duplication that disturb the url resolving process. — Mohammad

How do you start your uwsgi process? Your uwsgi process will need to be started from the location of your project's root directory.

I configure my uwsgi initialization file by giving it a PROJECT_HOME environment variable, which is defined in my process user's .bash_profile file.

In my process user's .bash_profile, I have:-

export PROJECT_HOME=/var/www/myproject

Then, in my uwsgi initialization file, I have:-

[uwsgi]

if-env = PROJECT_HOME
chdir = %(_)
touch-reload = %(_)/uwsgi.ini
daemonize = %(_)/myproject.log
endif =

if-env = VIRTUAL_ENV
virtualenv = %(_)
endif = 

socket = 127.0.0.1:3030
pidfile=/tmp/myproject.pid-3030
processes = 4
module = django.core.handlers.wsgi:WSGIHandler()
env = DJANGO_SETTINGS_MODULE=myproject.settings
master = True
vacuum = True
max-requests = 5000
logdate = True

enable-threads = True
single-interpreter = True

The chdir config in this uwsgi.ini file tells my uwsgi process to start the process from this directory and include this directory in PYTHONPATH so that my project's modules can be located.

If you also have a VIRTUAL_ENV environment defined, as you can see from my VIRTUAL_ENV configuration in the uwsgi.ini file, that VIRTUAL_ENV directory is also included in PYTHONPATH for the uwsgi process.

To run my uwsgi process, it is then as simple as running this command:-

uwsgi --ini /var/www/myproject/uwsgi.ini

This ensures that all your python modules (such as your urls.py) gets loaded correctly by your uwsgi process. Hope this helps!
