Django’s primary deployment platform is WSGI, the Python standard for web\nservers and applications.
\nDjango’s startproject management command sets up a minimal default\nWSGI configuration for you, which you can tweak as needed for your project,\nand direct any WSGI-compliant application server to use.
Django includes getting-started documentation for the following WSGI servers:
\napplication objectLink to this heading#The key concept of deploying with WSGI is the application callable which\nthe application server uses to communicate with your code. It’s commonly\nprovided as an object named application in a Python module accessible to\nthe server.
The startproject command creates a file\n<project_name>/wsgi.py that contains such an application callable.
It’s used both by Django’s development server and in production WSGI\ndeployments.
\nWSGI servers obtain the path to the application callable from their\nconfiguration. Django’s built-in server, namely the runserver\ncommand, reads it from the WSGI_APPLICATION setting. By default, it’s\nset to <project_name>.wsgi.application, which points to the application\ncallable in <project_name>/wsgi.py.
When the WSGI server loads your application, Django needs to import the\nsettings module — that’s where your entire application is defined.
\nDjango uses the DJANGO_SETTINGS_MODULE environment variable to\nlocate the appropriate settings module. It must contain the dotted path to the\nsettings module. You can use a different value for development and production;\nit all depends on how you organize your settings.
If this variable isn’t set, the default wsgi.py sets it to\nmysite.settings, where mysite is the name of your project. That’s how\nrunserver discovers the default settings file by default.
To apply WSGI middleware you can wrap the application\nobject. For instance you could add these lines at the bottom of\nwsgi.py:
from helloworld.wsgi import HelloWorldApplication\napplication = HelloWorldApplication(application)\nYou could also replace the Django WSGI application with a custom WSGI\napplication that later delegates to the Django WSGI application, if you want\nto combine a Django application with a WSGI application of another framework.
