     2 How to serve static files
       
     3 =========================
       
     4 
       
     5 Django itself doesn't serve static (media) files, such as images, style sheets,
       
     6 or video. It leaves that job to whichever Web server you choose.
       
     7 
       
     8 The reasoning here is that standard Web servers, such as Apache_ and lighttpd_,
       
     9 are much more fine-tuned at serving static files than a Web application
       
    10 framework.
       
    11 
       
    12 With that said, Django does support static files **during development**. Use
       
    13 the view ``django.views.static.serve`` to serve media files.

    16 .. _lighttpd: http://www.lighttpd.net/

    18 The big, fat disclaimer
       
    19 =======================
       
    20 
       
    21 Using this method is **inefficient** and **insecure**. Do not use this in a
       
    22 production setting. Use this only for development.
       
    23 
       
    24 For information on serving static files in an Apache production environment,
       
    25 see the `Django mod_python documentation`_.

    29 How to do it
       
    30 ============
       
    31 
       
    32 Just put this in your URLconf_::
       
    33 
       
    34     (r'^site_media/(?P<path>.*)$', 'django.views.static.serve', {'document_root': '/path/to/media'}),
       
    35 
       
    36 ...where ``site_media`` is the URL where your media will be rooted, and
       
    37 ``/path/to/media`` is the filesystem root for your media.
       
    38 
       
    39 You must pass a ``document_root`` parameter to indicate the filesystem root.
       
    40 
       
    41 Examples:
       
    42 
       
    43     * The file ``/path/to/media/foo.jpg`` will be made available at the URL
       
    44       ``/site_media/foo.jpg``.
       
    45 
       
    46     * The file ``/path/to/media/css/mystyles.css`` will be made available
       
    47       at the URL ``/site_media/css/mystyles.css``.
       
    48 
       
    49     * The file ``/path/bar.jpg`` will not be accessible, because it doesn't
       
    50       fall under the document root.
       
    51 
       
    52 .. _URLconf: ../url_dispatch/
       
    53 
       
    54 Directory listings
       
    55 ==================
       
    56 
       
    57 Optionally, you can pass a ``show_indexes`` parameter to the ``static.serve``
       
    58 view. This is ``False`` by default. If it's ``True``, Django will display file
       
    59 listings for directories.
       
    60 
       
    61 Example::
       
    62 
       
    63     (r'^site_media/(?P<path>.*)$', 'django.views.static.serve', {'document_root': '/path/to/media', 'show_indexes': True}),
       
    64 
       
    65 You can customize the index view by creating a template called
       
    66 ``static/directory_index``. That template gets two objects in its context:
       
    67 
       
    68     * ``directory`` -- the directory name (a string)
       
    69     * ``file_list`` -- a list of file names (as strings) in the directory
       
    70 
       
    71 Here's the default ``static/directory_index`` template::
       
    72 
       
    73     <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
       
    74     <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
       
    75     <head>
       
    76         <meta http-equiv="Content-type" content="text/html; charset=utf-8" />
       
    77         <meta http-equiv="Content-Language" content="en-us" />
       
    78         <meta name="robots" content="NONE,NOARCHIVE" />
       
    79         <title>Index of {{ directory }}</title>
       
    80     </head>
       
    81     <body>
       
    82         <h1>Index of {{ directory }}</h1>
       
    83         <ul>
       
    84         {% for f in file_list %}
       
    85         <li><a href="{{ f }}">{{ f }}</a></li>
       
    86         {% endfor %}
       
    87         </ul>
       
    88     </body>
       
    89     </html>
       
    90 
       
    91 Limiting use to DEBUG=True
       
    92 ==========================
       
    93 
       
    94 Because URLconfs are just plain Python modules, you can use Python logic to
       
    95 make the static-media view available only in development mode. This is a handy
       
    96 trick to make sure the static-serving view doesn't slip into a production
       
    97 setting by mistake.
       
    98 
       
    99 Do this by wrapping an ``if DEBUG`` statement around the
       
   100 ``django.views.static.serve`` inclusion. Here's a full example URLconf::
       
   101 
       
   102     from django.conf.urls.defaults import *
       
   103     from django.conf import settings
       
   104 
       
   105     urlpatterns = patterns('',
       
   106         (r'^/articles/2003/$', 'news.views.special_case_2003'),
       
   107         (r'^/articles/(?P<year>\d{4})/$', 'news.views.year_archive'),
       
   108         (r'^/articles/(?P<year>\d{4})/(?P<month>\d{2})/$', 'news.views.month_archive'),
       
   109         (r'^/articles/(?P<year>\d{4})/(?P<month>\d{2})/(?P<day>\d+)/$', 'news.views.article_detail'),
       
   110     )
       
   111 
       
   112     if settings.DEBUG:
       
   113         urlpatterns += patterns('',
       
   114             (r'^site_media/(?P<path>.*)$', 'django.views.static.serve', {'document_root': '/path/to/media'}),
       
   115         )
       
   116 
       
   117 This code is straightforward. It imports the settings and checks the value of
       
   118 the ``DEBUG`` setting. If it evaluates to ``True``, then ``site_media`` will be
       
   119 associated with the ``django.views.static.serve`` view. If not
       
   120 (``DEBUG == False``), then the view won't be made available.
       
   121 
       
   122 Of course, the catch here is that you'll have to remember to set ``DEBUG=False``
       
   123 in your production settings file. But you should be doing that anyway.
