I'm using Django on Appengine. I'm using the django reverse() function everywhere, keeping everything as DRY as possible.

However, I'm having trouble applying this to my client-side javascript. There is a JS class that loads some data depending on a passed-in ID. Is there a standard way to not-hardcode the URL that this data should come from?

var rq = new Request.HTML({
    'update':this.element,
}).get('/template/'+template_id+'/preview'); //The part that bothers me.
