Body
My fixture data contains multiple array.Out of this multiple array <code>cart_items</code> contains some product data. I am trying to calculate total no of products available in cart data (based on length of <code>cart_items</code> items) but i am not able to calculate no of items are present in <code>cart_items</code>. In router i have selected application fixture as model for current route,as follow : <pre><code> Astcart.IndexRoute = Ember.Route.extend({ model: function() { return Astcart.Application.find(); } }); </code></pre> Computed property code : <pre><code>Astcart.IndexController = Ember.ArrayController.extend({ tot_cart_prd: function() { return this.get("model.cart_items").get('length'); }.property("@each.isLoaded") }); </code></pre> And my fixture data is : <pre><code>Astcart.Application.adapter = Ember.FixtureAdapter.create(); Astcart.Application.FIXTURES = [ { "logo_url": "img/logo.jpg", "logged_in": { "logged": true, "username": "sachin", "account_id": "4214" }, "category_list": [ { "id": "1", "name": "Mobiles & Accessories" }, { "id": "2", "name": "Computers & Software" }, { "id": "3", "name": "Fashion" }, { "id": "4", "name": "Electronics" }, { "id": "5", "name": "Watches & Jewelry" }, { "id": "6", "name": "Health & Beauty" }, { "id": "7", "name": "Games" }, { "id": "8", "name": "Books & Entertainment" }, { "id": "9", "name": "Gaming" }, { "id": "10", "name": "Shoes & Bags" } ], "cart_items": [ { "id": "1", "name": "Samsung Galaxy Tab 2", "qty": "1", "price": "1245.12", "subtotal": "7842.23" }, { "id": "2", "name": "Samsung Galaxy Tab 2", "qty": "1", "price": "1245.12", "subtotal": "7842.23" }, { "id": "3", "name": "Samsung Galaxy Tab 2", "qty": "1", "price": "1245.12", "subtotal": "7842.23" } ] } ]; </code></pre> I have posted my code <a href="http://jsfiddle.net/sachin1989/8SEvk/1/" rel="nofollow">here(JSFiddle)</a>. Can any one tell me why <code>this.get("model.cart_items")</code> is returning null?

Guidance

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.
