Django settings.py not being detected

Question

I'm pretty new to Django and I'm having some difficulty getting my settings.py to load properly. I'm getting the following error:

ImproperlyConfigured at /admin

Put 'django.contrib.admin' in your INSTALLED_APPS setting in order to use the admin application.

However, my settings.py INSTALLED_APPS looks as follows:

INSTALLED_APPS = (
 'django.contrib.auth',
 'django.contrib.contenttypes',
 'django.contrib.sessions',
 'django.contrib.sites',
 'django.contrib.messages',
 'django.contrib.staticfiles',
 'django.contrib.admin',
 'squaredcrm' )

Looking through the error log, I've noticed its not picking up any of my changes to installed apps:

Django Version: 1.4.3 Python Version: 2.7.3 Installed Applications: ('django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.sites', 'django.contrib.messages', 'django.contrib.staticfiles') Installed Middleware: ('django.middleware.common.CommonMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware')

I cannot figure this out for the life of me. Any other changes seem to be working, but this field will not update. Any ideas?

Answer 1

I know it's a silly question, but did you restart your server after making the changes?

By default, production (by which I mean Apache-based, and perhaps other) instances of Django do not auto-reload on changes. The Django development server will auto-reload, as long as you don't specifically tell it not to.

You have to restart (or stop and then start) an Apache-based Django for it to see the file changes.

Important tip: do not run a production site off of the development server. It is slow, slow, slow, and probably insecure in ways I don't know about.

• SquaredSoft: You sir, are a genius. I did not even think to restart Apache. This has solved my problem. Thank you all for your help, and happy holidays.
• Peter Rowell: I'm not sure that having done several face-plants on this particular problem qualifies as "genius" -- maybe more like "slow learner." :-)

Answer 2

If other changes are picked up, this is probably because INSTALLED_APPS is being redefined somewhere in your settings.py file.

This could be:

• At a subsequent line.
• In an import (likely a from x import *).

• SquaredSoft: Hello and thank you for the quick reply. I appreciate the help. Sadly, there are no imports in the settings.py file as is there nowhere else that installed_apps is being redefined in that file.
• SquaredSoft: Edit: I stand corrected, this is still an issue. I apologize.
• kartheek: To configure Admin in your application look at this
• SquaredSoft: Hi, that is the guide I followed to configure the admin setup. I'm stuck because it is not loading.
• Lincoln Bergeson: This was it for me! Rewriting my ALLOWED_HOSTS at the beginning of the file, without realizing it was already defined half a page down. Thanks four years later :-)
