Emberjs How To Load Multiple Models On The Same Route

Ember.js is a popular JavaScript framework known for its robust features that make building complex web applications easier and organized. In this article, we'll explore a practical how-to on loading multiple models on the same route in Ember.js.

When working on a web application, it's common to encounter scenarios where you need to display data from more than one source on a single page or route. Ember.js provides a convenient way to handle this requirement by allowing you to load multiple models on the same route effortlessly.

To start loading multiple models on the same route in Ember.js, you first need to define your route in the router.js file. In the route definition, you can specify which models to load using the model hook. Here's an example of how you can define a route that loads two models:

Javascript

// router.js

Router.map(function() {
  this.route('example-route', {
    model() {
      return Ember.RSVP.hash({
        model1: this.store.findAll('model1'),
        model2: this.store.findAll('model2')
      });
    }
  });
});

In the code snippet above, we defined an 'example-route' and used the model hook to load two models - 'model1' and 'model2' asynchronously using Ember's RSVP.hash method. This method allows you to fetch multiple models concurrently.

Once you have defined your route to load multiple models, you can access these models in your route's corresponding template to display the data. Here's an example of how you can access and display the data in your template:

Handlebars

{{! example-route.hbs }}

<h1>Model 1 Items:</h1>
<ul>
  {{#each model.model1 as |item|}}
    <li>{{item.name}}</li>
  {{/each}}
</ul>

<h1>Model 2 Items:</h1>
<ul>
  {{#each model.model2 as |item|}}
    <li>{{item.title}}</li>
  {{/each}}
</ul>

In the template above, we are iterating over the 'model1' and 'model2' arrays to display the data from each model. By accessing the models as 'model.model1' and 'model.model2', you can render the data fetched in your Ember.js application.

Remember to handle any error responses that may occur when fetching the models and provide appropriate error handling in your route to ensure a smooth user experience.

In conclusion, loading multiple models on the same route in Ember.js is a powerful feature that enables you to fetch and display data from different sources seamlessly. By defining your route and loading multiple models using the model hook, you can efficiently manage complex data requirements in your web application.
