Backbone Nested Models... how do they work?

So I'm using Backbone for my web application and I'm having trouble figuring out how to work with nested models. I have a model based on a java class whos JSON would look something like this:

"AdminSettings":
{
    "defaults": {
        "deletable":true,
        "transferable":false;
        "issueLimit":1
    }
    "displaySettings": {
        "tabs":2,
        "amounts:[10,20]
    }
}

Currently, I have an endpoint set up and a backbone model for the AdminSettings object. I was wondering if there was a specific way to get all the backbone benefits for the objects inside AdminSettings. For example, currently I have to use:

adminSettings.get("defaultValues").shareable

But I want to use:

adminSettings.get("defaultValues").get("shareable")

This isn't the only benefit I'm trying to obtain, just an example.

So yeah, what would be a good way to go about this. I was thinking making a backbone model for each one of the nested objects and setting up endpoints for each one of those, but I'm not completely sure. Anyways, thanks for looking.

You could write your own custom backbone parser:

var DisplaySettingsModel = Backbone.Model.extend({});
var DefaultValuesModel = Backbone.Model.extend({});

var AdminSettingsModel = Backbone.Model.extend({

    model: {
        defaultValues: DefaultValuesModel
        displaySettings:  DisplaySettingsModel
    },

    parse: function(response){
        response["defaultValues"] = new DefaultValuesModel(response["defaultValues"], {parse:true});
        response["displaySettings"] = new DisplaySettingsModel(response["displaySettings"], {parse:true});
        return response;
    }
});
