Select View Template By Model Type Object Value Using Ember Js

Ember.js is a powerful JavaScript framework widely used for building web applications. One of the key features of Ember.js is its ability to efficiently handle data-binding and updating the user interface by using templates that are closely integrated with its powerful model layer.

In this guide, we will explore how to select a view template based on the type of model object in Ember.js. This can be particularly useful when you need to display different views or layouts depending on the data you're working with.

To achieve this in Ember.js, you can utilize the built-in `Ember.Handlebars` templating engine along with the framework's powerful routing capabilities. Let's walk through the steps to select a view template based on the type of model object in your Ember.js application:

Step 1: Define Your Model and Templates
First, you need to define your model objects and the corresponding view templates in your Ember.js application. For example, let's say you have two model types: `User` and `Admin`. You would create model classes for each type and corresponding Handlebars templates for their views.

Step 2: Configure the Route
Next, you need to configure your Ember.js route to dynamically select the appropriate template based on the model object type. You can achieve this by using the `renderTemplate` method in your route file. Inside this method, you can check the type of the model object and render the corresponding template.

Step 3: Render the Template
Now, when you navigate to a route that corresponds to a specific model object, Ember.js will automatically select and render the appropriate view template based on the model type. This allows you to display different layouts or components for different types of data in your application.

Here is an example of how you can select and render a view template based on the type of model object in Ember.js:

// Route file for the User model
App.UserRoute = Ember.Route.extend({
  model() {
    return this.store.find('user', params.user_id);
  },
  renderTemplate() {
    let model = this.modelFor('user');
    if (model instanceof App.Admin) {
      this.render('admin-template');
    } else {
      this.render('user-template');
    }
  }
});

By following these steps, you can dynamically select and render view templates based on the type of model object in your Ember.js application. This allows for greater flexibility in designing your user interface and responding to different data scenarios.

In conclusion, Ember.js provides robust tools for handling data-binding and rendering templates based on model types. By leveraging the framework's routing and template capabilities, you can create dynamic and responsive web applications that adapt to the data being presented.
