How to deploy with WSGI
|
|
=======================
|
|
|
|
Django's primary deployment platform is WSGI_, the Python standard for web
|
|
servers and applications.
|
|
|
|
.. _WSGI: http://www.wsgi.org
|
|
|
|
Django's :djadmin:`startproject` management command sets up a simple default
|
|
WSGI configuration for you, which you can tweak as needed for your project, and
|
|
direct any WSGI-compliant webserver to use. Django includes getting-started
|
|
documentation for the following WSGI servers:
|
|
|
|
.. toctree::
|
|
:maxdepth: 1
|
|
|
|
modwsgi
|
|
apache-auth
|
|
gunicorn
|
|
uwsgi
|
|
|
|
The ``application`` object
|
|
--------------------------
|
|
|
|
One key concept of deploying with WSGI is to specify a central ``application``
|
|
callable object which the webserver uses to communicate with your code. This is
|
|
commonly specified as an object named ``application`` in a Python module
|
|
accessible to the server.
|
|
|
|
The :djadmin:`startproject` command creates a :file:`projectname/wsgi.py` that
|
|
contains such an application callable.
|
|
|
|
.. note::
|
|
|
|
Upgrading from a previous release of Django and don't have a :file:`wsgi.py`
|
|
file in your project? You can simply add one to your project's top-level
|
|
Python package (probably next to :file:`settings.py` and :file:`urls.py`)
|
|
with the contents below. If you want :djadmin:`runserver` to also make use
|
|
of this WSGI file, you can also add ``WSGI_APPLICATION =
|
|
"mysite.wsgi.application"`` in your settings (replacing ``mysite`` with the
|
|
name of your project).
|
|
|
|
Initially this file contains::
|
|
|
|
import os
|
|
|
|
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "mysite.settings")
|
|
|
|
# This application object is used by the development server
|
|
# as well as any WSGI server configured to use this file.
|
|
from django.core.wsgi import get_wsgi_application
|
|
application = get_wsgi_application()
|
|
|
|
The ``os.environ.setdefault`` line just sets the default settings module to
|
|
use, if you haven't explicitly set the :envvar:`DJANGO_SETTINGS_MODULE`
|
|
environment variable. You'll need to edit this line to replace ``mysite`` with
|
|
the name of your project package, so the path to your settings module is
|
|
correct.
|
|
|
|
To apply `WSGI middleware`_ you can simply wrap the application object
|
|
in the same file::
|
|
|
|
from helloworld.wsgi import HelloWorldApplication
|
|
application = HelloWorldApplication(application)
|
|
|
|
You could also replace the Django WSGI application with a custom WSGI
|
|
application that later delegates to the Django WSGI application, if you want to
|
|
combine a Django application with a WSGI application of another framework.
