     2WSGI entrypoints

     4Overview
     5--------
     6
     7The motivation behind this module is to expose the WSGI application that
     8exists in Django to the actual Django user project. The idea is that you
     9have a documented way to apply WSGI middlewares that are then being used by
     10both the internal WSGI development server as well as any other WSGI server
     11in production.
     12
     13The way it works is that there are a handful of WSGI application objects:
     14
     15-   django.core.handlers.wsgi.WSGIHandler: this is the implementation of the
     16    actual Django WSGI dispatcher and it should be considered an
     17    implementation detail. While users are free to subclass and extend it,
     18    it's not necessarily supported.
     19-   django.core.handlers.wsgi.application: this is the documented WSGI
     20    application which is used by default.
     21-   django.core.handlers.wsgi.django_application: this is the actual WSGI
     22    application that is passed to the servers. It's internally proxying to
     23    the configured WSGI application and will most likely be a (decorated)
     24    version of the `application`.
     25
     26The reason why we have multiple applications here is because of the
     27ability to apply middlewares.  Basically `application` is the WSGI
     28application without any middlewarse applied, `django_application` is a
     29proxy to the base application + all applied middlewares.
     30
     31The middlewares are added according to the WSGI_APPLICATION configuration
     32setting which points to a module that imports the `application` as
     33`application` and can apply middlewares.
     34
     35If the WSGI_APPLICATION setting is ``None`` (which is the case for upgraded
     36applications from before we had exposed WSGI support) instead of the regular
     37application, the `application` is used.
     38
     39The WSGI_APPLICATION
     40--------------------
     41
     42The WSGI_APPLICATION configuration setting points to an actual WSGI
     43application.  By default the project generator will configure that a file
     44called `projectname.wsgi` exists and contains a global variable named
     45`application`. The contents look like this::
     46
     47    from django.core.handlers.wsgi import application
     48
     49This can be used to apply WSGI middlewares::
     50
     51    from helloworld.wsgi import HelloWorldApplication
     52    application = HelloWorldApplication(application)
     53
     54Of course usually you would have an actual Django WSGI application there, but
     55it also might make sense to replace the whole Django WSGI application with
     56a custom one that later delegates to the Django one (for instance if you
     57want to combine a Django application with an application of another framework).
