settings file being imported four times

[Tomas Neme]

is it normal that the settings file is being imported four times? I'd give more info, but I really have no clue what's going on

here's my manage.py:

from django.core.management import execute_manager
import imp
try:
    imp.find_module('local_settings') # Assumed to be in the same directory.
except ImportError:
    import sys
    sys.stderr.write("""Error: Can't find the file 'local_settings.py' in the directory containing %r.
It appears you've customized things.
You'll have to run django-admin.py, passing it your settings module.
(If the file local_settings.py does indeed exist, it's causing an ImportError somehow.)
""" % __file__)
    sys.exit(1)

import local_settings

if __name__ == '__main__':
    execute_manager(local_settings)


And I printed a stacktrace at the top of my local_settings file. It does a 'from settings import *' at the top.

Yes, when I put a print statement in my settings file, it prints out twice everytime I start the server. The file has to be imported in multiple places, and so it gets executed multiple times. I'm not sure what your error is, but it doesn't seem to be related to the multiple imports.

Hi Tomas,

If you're using Django 1.3, and you're using the development server
(which it looks like you are), then yes, it's normal. See:

http://blog.dscpl.com.au/2010/03/improved-wsgi-script-for-use-with.html

for an excellent explanation of what is going on.

If you're using Django 1.4, you should only be seeing 2 imports; one
of the imports mentioned in Graham's article has been cleared out.

Yours,
Russ Magee %-)
