Django Dynamic Statics

This little app allows you to dynamically change Django's MEDIA_URL and STATIC_URL on a per request basis based on the clients REMOTE_ADDR.

The use case this app was that the local web server has all the large media assets but the remote server is the public facing web server. If you were at the local location it sure would be nice to get the assets directly instead of proxying via the remote web server.

Prerequisites

django-dynamicstatics depends on iptools and django-ipware which should get installed automatically when you install via pip or easy_install.

Setup

You'll have to edit your settings.py file.

Original

MEDIA_URL = '/media/'
...
STATIC_URL = '/static/'

Modified

Add two new variables. The format of MEDIA_URLS and STATIC_URLS is a dict with a string or a list of ip addresses as the key and a url string as the value. Use iptools to effortlessly make a range of ip addresses.

If the clients remote address doesn't match any key then MEDIA_URL or STATIC_URL is used as appropriate.

However, if there is a 'default' key in *_URLS then that will take precendence over *_URL.

import iptools

MEDIA_URLS = {
    '127.0.0.1': 'http://localhost/media/',
    #iptools.IpRange(''): '',
    iptools.IpRangeList('192.168.1.0/24','2.3.4.5'): "https://www2.local/media/",
    'default': 'http://local_server/media/', # takes precendence over MEDIA_URL
}
...
STATIC_URLS = {
    '127.0.0.1': 'http://localhost/static/',
    #iptools.IpRange(''): '',
    iptools.IpRangeList('192.168.1.0/24','2.3.4.5'): "https://www2.local/static/",
    'default': 'http://local_server/static/', # takes precendence over STATIC_URL
}

# add dynamicstatics to INSTALLED_APPS
INSTALLED_APPS = [
...
  'dynamicstatics',
]

Templates

You need to change {{ MEDIA_URL }} and {{ STATIC_URL }} to template tags.

Original

<img src="{{ MEDIA_URL }}some_image.jpg">

{% load media_url %}

<img src="{% media_url %}some_image.jpg">
