    <p>im having problem with backbone view-model communication, view should be listening events from model, so function couponReader is suppossed to get the data from model and add to the cart after a sort of confirmation. Any help is appreciated</p> <pre><code>define([ 'jquery', 'underscore', 'backbone', 'text!templates/menu/menu.html', 'text!templates/menu/cartItem.html', 'collections/cart', 'views/menu/topBar', 'models/coupon', 'swipe' ], function ($, _, Backbone, menuTemplate, cartItemTemplate, Cart, TopBarView, Coupon) { var slider; var sliderPosition = 0; var top; var menuView = Backbone.View.extend({ el:$("body"), events:{ "click #keno50":"addKeno50", }, initialize:function () { this.couponReader(); }, render:function () { this.el.html(menuTemplate); // TODO - Memory leak here :O new TopBarView({ el: this.$('#topBar') }).render(); this.slider = new Swipe(document.getElementById('slider'), {startSlide:sliderPosition}); this.resizeScreen(); return this; }, couponReader:function () { var coupon = new Coupon({ //problem here name: Coupon.getCoupon().name, price: Coupon.getCoupon().price }); Cart.add(coupon); }, addKeno50:function () { var keno50 = { name:"Keno", price:50 } Cart.add(keno50); sliderPosition = this.slider.getPos(); this.render(); } }); return new menuView; }); </code></pre> <p>model class: it listens to the server in loop, get data from server whenever a data is loaded.</p> <pre><code>define(['jquery', 'underscore', 'backbone'], function ($,_, Backbone) { var Coupon = Backbone.Model.extend({ initialize:function () { this.getCoupon(); //console.log("funkar*?"); }, getCoupon : function() { var XHR = this.getRequest(); XHR.done(function(data){ var keno10 = { name: data.description, price: parseInt(data.price)} var price = parseInt(data.price); var name = data.description; var status = data.ok; }) }, getRequest:function() { var fn = arguments.callee; var XHR = $.ajax({ url: '/nextdocument', type: 'GET', async: true, cache: false, timeout: 11000, //vänta på svar från servern om ingen inläsning success:function(data) { var name = data.description; var price = data.price; console.log("read--&gt; " + name + price); setTimeout(fn, 1000); if (data.ok == "true") { data["ok"] = data.ok; $.ajax( { url: "/customerdone", data: JSON.stringify(data), processData: false, type: 'POST', contentType: 'application/json' } ) }else{ //no document if no read in console.log("error--&gt; " + data.errorMessage) } } }) return XHR; } }); return Coupon; }); </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.
