Ember.js Advanced Routing: Handling Dynamic Segments in Routes

Ember.js is a powerful JavaScript framework that allows developers to build complex web applications. One of the key features of Ember.js is its advanced routing system, which enables developers to handle dynamic segments in routes. In this article, we will explore how to use Ember.js to handle dynamic segments in routes.

Understanding Dynamic Segments in Ember.js

Dynamic segments in Ember.js are route parameters that are passed to a route from the URL. These parameters can be used to retrieve data from a server or to perform other actions. Dynamic segments are defined in the route's path using a colon (:) followed by the name of the parameter.

Defining Dynamic Segments in Routes

To define a dynamic segment in a route, you need to add a colon (:) followed by the name of the parameter to the route's path. For example:

// app/router.js
Router.map(function() {
  this.route('posts', function() {
    this.route('post', { path: '/:post_id' });
  });
});

In this example, the `post` route has a dynamic segment `post_id` that is passed to the route from the URL.

Accessing Dynamic Segments in Routes

To access a dynamic segment in a route, you can use the `params` object. The `params` object is a hash of all the dynamic segments in the route. For example:

// app/routes/posts/post.js
import Route from '@ember/routing/route';

export default class PostRoute extends Route {
  model(params) {
    return this.store.findRecord('post', params.post_id);
  }
}

In this example, the `model` hook uses the `params.post_id` to retrieve a post from the store.

Using Dynamic Segments in Templates

To use a dynamic segment in a template, you can use the `params` object. For example:

// app/templates/posts/post.hbs
{{model.title}}
