I have not had to do this myself, so have no code snippet to share. It does seem like a commonly-discussed thing, but in a quick Google search I didn't find anything that matched exactly. This page: http://remysharp.com/2007/01/20/auto-populating-select-boxes-using-jquery-ajax/ discusses doing exactly what you want with jQuery and Ajax...and PHP. So not quite what you are looking for. But this page: http://www.packtpub.com/article/enhancing-the-user-interface-with-ajax discusses adding jQuery to a Django app and doing other cool stuff with it. So probably you can glean bits of information from both and put it together to do what you are looking for. I do believe you need to learn a little Javascript/Ajax to do this.
