I\'m trying to use certain jQuery plugins in my Django admin site.
Django admin sets the jQuery namespace to django.jQuery
(to avoid conflicts)
Actually, most plugins will require "jQuery" - not $ - to be available, and then provide $ themselves as in dmidz's answer.
Therefore, insert
var jQuery = django.jQuery;
before your external references. If you're loading a bunch of thirdparty jQuery plugins, put the above line in a script tag that preceeds the plugins.
