Django Debug=False returns 500 due to admin.autodiscover()

0

When setting DEBUG=True Django returned a 500 error. ALLOWED_HOSTS are set, static files are served correctly,...all should be in order.

After a bit of digging it seems related to admin.autodiscover() in urls.py. The problem is fixed when I uncomment admin.autodiscover(). The website works but I loose access to the admin interface since admin.autodiscover is left out.

#urls.py
from django.conf import settings
from django.conf.urls.static import static
from django.conf.urls import patterns, include, url
from django.contrib.sitemaps import GenericSitemap
from django.contrib.sitemaps.views import sitemap
from django.contrib import sitemaps
from django.core.urlresolvers import reverse

from django.contrib import admin
admin.autodiscover()

I'm not quite sure what's going on here. Anyone know how to fix this issue?

Thanks,

Based on the last statement in your error log you have a python search path issue. You can easily fix the path via these instructions. One helpful way to check the path is via the python shell.

Thanks for the quick response.

The paths seem to be added correctly in httpd.conf:

#httpd.conf
ThreadsPerChild 5
WSGIPythonPath /home/nnn/webapps/ecommerce:/home/nnn/webapps/ecommerce/src:/home/nnn/webapps/ecommerce/lib/python2.7
WSGIDaemonProcess ecommerce processes=2 threads=12 python-path=/home/nnn/webapps/ecommerce:/home/nnn/webapps/ecommerce/src:/home/nnn/webapps/ecommerce/lib/python2.7
WSGIProcessGroup ecommerce

Checking to see if they were added correctly in the shell:

[nnn@web431 src]$ python2.7 manage.py shell
Python 2.7.8 (default, Oct  7 2014, 19:28:26)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-4)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
(InteractiveConsole)
>>> import sys
>>> print sys.path
['/home/nnn/webapps/ecommerce/src', '/home/nnn/webapps/ecommerce/lib/python2.7', '/home/nnn/lib/python2.7/pip-1.5.6-py2.7.egg', '/home/nnn/lib/python2.7', '/usr/local/lib/python27.zip', '/usr/local/lib/python2.7', '/usr/local/lib/python2.7/plat-linux2', '/usr/local/lib/python2.7/lib-tk', '/usr/local/lib/python2.7/lib-old', '/usr/local/lib/python2.7/lib-dynload', '/home/nnn/.local/lib/python2.7/site-packages', '/usr/local/lib/python2.7/site-packages', '/usr/local/lib/python2.7/site-packages/PIL']

I feel like I'm overlooking something here as all seems to be set up correctly?

Thanks!

If you 'ls' each of those paths does a module named Order exist in any of them?

(18 Dec '14, 22:22) johns

Under /home/nnn/webapps/ecommerce/src my dir structure looks like:

accounts

carts

ecommerce

orders

--models.py

----where class Order is defined

products

...

App works fine locally as well as on production but only with DEBUG set to TRUE. Don't quite understand why no error is displayed in those cases.

(19 Dec '14, 08:25) nathandh8

I notice the 'orders' directory has a lowercase O, are you using a file-system locally that is not case-sensitive? The file-system on the server is case-sensitive, so try making it a capitol O.

(19 Dec '14, 23:17) johns

Thanks for all your help. The issue is reseolved. Turned out is was related to the following lines in orders.model.py

from django.contrib.auth import get_user_model

User = get_user_model()

Don't quite understand why but I can do without the user model here so I just left it out.
