A small conversion layer to make backbone.js and django-tastypie work together happily.
Add backbone_tastypie to your INSTALLED_APPS setting, and add the following to your base template:
<script type="text/javascript" src="{{ STATIC_URL }}js/backbone-tastypie.js"></script>
Specifically, it overrides Backbone.sync to do a GET request after creating an object (if there is no response body), and overrides Backbone.Model.prototype.idAttribute, Backbone.Model.prototype.url, Backbone.Model.prototype.parse and Backbone.Collection.prototype.parse.
Backbone.Collection.prototype.url is overridden so it can build urls for a set of models when using the fetchRelated method in Backbone-relational.
