import os
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "myapp.settings")
from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()
Problem
Cannot deploy Django app on WAMP given the context described above.
A "Hello World" test wsgi application works fine, so I have confirmed that mod_wsgi is active.
I get the error:
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, me#mine.com and inform them of the time the error occurred, and anything you might have done that may have caused the error.
More information about this error may be available in the server error log.

The static folder works fine, I can access all static files within the directory by pointing to:
http://192.168.20.11:8080/myapp/static

I don't understand the function of middleware in this case and was under the impression it wasn't necessary to use middleware.
Regarding the system path, when I add:
WSGIPythonPath "c:/wamp/www/myapp"
to my VirtualHost in the httpd.conf file, the server refuses to start up.
Objective
To deploy a working Django app (that has been developed and tested locally using the Django development server) to a Microsoft SBS network without using IIS. I tried deploying on IIS and ran into difficulties early on so switched to WAMP.
I'm new to Python and Django and have never deployed a web app on any production server (I am an R programmer that has generally used programming for math and statistics).
Any advice that would help in achieving this objective, regardless of method, will be much appreciated!

Answer 1

This has nothing to do with middleware, that's just where the error was encountered. The error itself is the last line: "Could not import settings 'myapp.settings'". This is almost certainly because you haven't modified the PYTHONPATH - either in your wsgi or your Apache conf - to put "myapp" on the path.
See for instance the example Apache conf in the Django docs - there's a WSGIPythonPath directive there to add the app to the Python path, which you don't have.

Answer 2

Placing a WSGIPythonPath directive in the httpd.conf prevented the server from starting, but the problem was indeed related to the path not being declared.
Adding:
sys.path.append("c:/wamp/www/myapp")
to the wsgi.py file did the trick.
Thanks to Daniel Roseman for putting me on the right track.
