  1. PORight way to fetch and retrieve data in Backbone.js
    text
    copied!<p>I’m trying to understand how and where to use data after a fetch using Backbone.js but I’m a little confused.<br/> I’ll explain the situation.<br/> I have an app that, on the startup, get some data from a server. Three different kind of data.<br/> Let’s suppose Airplanes, Bikes, Cars.<br/> To do that, I’ve inserted inside the three collections (Airplanes, Cars, Bikes) the url where to get these data.<br/> I’ve overwrited the parse method, so I can modify the string that I get, order it, and put it in an object and inside localstorage. I need it to be persistent because I need to use those 3 data structure.<br/> So with a fetch i get all those data and put them inside localstorage. Is it correct doing it that way?<br/></p> <p>Now i need to make other calls to the server, like “get the nearest car”.<br/> In the view i need to see the color, name and model of the car, all that informations are inside the object “Cars” in localstorage.<br/> In my view “showcars.view” I just call a non-backbone js, (not a collection, model or view) where i get all the informations i need. In this js i do:</p> <pre><code>var carmodel = new Car(); //car is the backbone model of the cars carmodel.url = '/get/nearest/car'; //that give id of the nearest car carmodel.fetch ({ success: function () {} //here i search the Cars object for a car with the same id //and get name, color, model and put them in sessionstorage }) </code></pre> <p>So after that call, in the view I can get the data I need from the sessionstorage. Is that a bad way of doing things? If so, how i should fetch and analyze those informations? I should do all the calls and operations inside the models?<br/> Thanks</p>
