Body
I have a JSON File looking like this: JSON : <pre><code>{ "clefs": [ {"title": "..", "path": ".."}, ... , {"title": "..", "path": ".."} ], .... "rests": [ {"title": "..", "path": ".."}, ... , {"title": "..", "path": ".."} ] } </code></pre> This is a nested JSON, right? So I try to convert that into Model/Collections nested into <code>Backbone.js</code> like this: Backbone.js : <pre><code>window.initModel = Backbone.Model.extend({ defaults: { "title": "", "path": "" } }); window.CustomCollection = Backbone.Collection.extend({ model: initModel }); window.Init = Backbone.Model.extend({ url : function(){ return "/api/data.json" }, parse: function(response) { clefs = new CustomCollection(); clefs.add(response.clefs); this.set({clefs: clefs}); ..... rests = new CustomCollection(); rests.add(response.rests); this.set({rests: rests}); } }); </code></pre> Now I came out with a Model and into its Attributes my Collection: clefs, ..., rests. When it's come to pass my Collection to a View I cannot! I made this Router : <pre><code>$(document).ready(function() { var AppRouter = Backbone.Router.extend({ routes: { "" : "init" }, init: function(){ this.initial = new Init(); this.initialView = new InitView({model: this.initial}); this.initial.fetch(); } }); var app = new AppRouter(); Backbone.history.start(); }); </code></pre> View : <pre><code>window.InitView = Backbone.View.extend({ initialize : function() { this.model.bind("reset", this.render, this);//this.model.attributes send my 4 Collections Models back! But impossible to extract with "get" these Attributes }, render : function() { console.log("render"); } }); </code></pre> It's an ugly situation right now!! I have a Backbone Model with Attributes(Collections) but I can't extract these Attributes, I try with JSON(), get, _.each, _.map but no success! What i want is to extract my Collections out from the Model name's "initial"!! <code>this.initial.attributes</code> return an Object with my collections into it! but i cannot pass those to the View! Update 1 : Now the Model is passed to the View but i always cannot access his attributes with get or send his attributes to other Views! the render can not be fired too!!! Update 2 : After several Days of headaches i take the resolution to make it simple! Why? cause i just have 4 Collections for now : clefs, accidentals, notes and rests MODEL : <pre><code>window.initModel = Backbone.Model.extend({ defaults: { "title": "", "path": "" } }); window.ClefsCollection = Backbone.Collection.extend({ model: initModel, url: "/api/data.json", parse: function(response){ return response.clefs; } }); ... and so on </code></pre> ROUTER : <pre><code>.... this.clefsColl = new ClefsCollection(); this.clefsColl.fetch(); this.clefsCollView = new ClefsView({collection: this.clefsColl}); .... </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
