EmberJS - Specifying a Route's Model



You can specify a routes model, by defining the template name in the route which is the same name as the data template and implement its model hook.

Ember.Route.extend ({
   model: function() {
      return { //value-1 },{ //value-2 },{..},{ //value-n };
   }
});

In the above code value-1 to value-n variables are used to store the values which are being called in the template.

The following table lists down the different types of Specifying Routes model −

S.No. Specifying Routes & Description
1 Dynamic Models

It defines the routes with dynamic segment which is used by Ember to access the value from URL.

2 Multiple Models

You can define multiple models using the RSVP.hash which further uses the objects to return the promises.

Example

The following example shows how to specify a route for displaying data. Create a new route as specified in the previous chapters. Now open the router.js file with the following code to define the URL mappings −

import Ember from 'ember';                   
//Access to Ember.js library as variable Ember
import config from './config/environment';
//It provides access to app's configuration data as variable config 

//The const declares read only variable
const Router = Ember.Router.extend ({
   location: config.locationType,
   rootURL: config.rootURL
});

Router.map(function() {
   this.route('specifyroute');
});

//It specifies Router variable available to other parts of the app

export default Router;   

Create the application.hbs file and add the following code −

//link-to is a handlebar helper used for creating links
{{#link-to 'specifyroute'}}Click here to see details{{/link-to}}
{{outlet}} //It is a general helper, where content from other pages will 
appear inside this section

Open the specifyroute.hbs file created under app/templates/ with the following code −

<h2>List of Players</h2>
<ul>
   //The <i>each</i> helper to loop over each item in the array provided from model() hook
   {{#each model as |player|}}
      <li>{{player}}</li>
   {{/each}}
</ul>
{{outlet}}

To construct the URL, you need to implement model to return the values −

import Ember from 'ember';

export default Ember.Route.extend ({
   //The model() method returns the data which you want to make available to the template
   model() {
      return ['MS Dhoni', 'Steve Smith', 'Jason Roy','AB de Villiers','Kane Williamson'];
   }
});
