don't override the default idAttribute

[Lacrymology]

if there's a good reason for this, it can be disregarded, but why is the idAttribute option overriden instead of always just using the url() method?

in my use case, I've got an Option model with an Options collection, and I want to create a <select> with the options as <options>, and I end up with three ugly possibilities:

• end up with a bunch of <option value="/api/v1/option/<id>"> which is semantically wrong
• do <option value="<%= option.get("id") %>"> when <option value="<%= option.id %>"> would suffice and is more natural AND THEN I've got to do collection.find(function(x) { return x.get('id') == id }) instead of just collection.get(id)
• set idAttribute: "id" in all of my models.. which means explicitly set things back to default.

With the current url() override in https://github.com/PaulUithol/backbone-tastypie/blob/master/backbone_tastypie/static/js/backbone-tastypie.js#L102 this shouldn't be necessary

this is a duplicate for #20 I see

I would like to leave this open to discussion. What's the main argument to keep things as they are? It looks like the strongest argument here is "resource_uri is the only attribute that can be assumed to be present" bit in #20 (comment)
