How to Get Dynamics Routes From Url With Ember.js?

To get dynamic routes from a URL with Ember.js, you can use the Route and Model hooks provided by Ember's routing system. By defining dynamic segments in your route's path, you can extract the dynamic parameters from the URL and use them to fetch the relevant data for that route.

For example, if you have a route defined as post/:post_id, Ember will automatically extract the post_id parameter from the URL and pass it to the model hook of your route. Inside the model hook, you can make a request to your backend API to fetch the data for the specified post ID.

By following this approach, you can create dynamic routes in Ember.js that respond to changes in the URL and fetch the appropriate data based on the dynamic parameters provided in the URL. This allows you to build flexible and powerful web applications that can handle a wide range of dynamic routing scenarios.

How to handle dynamic route events in Ember.js?

To handle dynamic route events in Ember.js, you can use the model hook in your route definition.

1. Define a dynamic route in your router.js file, specifying the dynamic segment in the path:

1
2
3

Router.map(function() {
  this.route('dynamic-route', { path: '/dynamic-route/:dynamic_segment' });
});

1. Define the corresponding route file, and use the model hook to fetch data based on the dynamic segment:

1
2
3
4
5
6
7
8
9

// routes/dynamic-route.js

import Route from '@ember/routing/route';

export default class DynamicRouteRoute extends Route {
  model(params) {
    return this.store.findRecord('dynamicModel', params.dynamic_segment);
  }
}

1. Access the dynamic segment value in your template using the model property:

1

{{model.dynamicProperty}}

By following these steps, you can handle dynamic route events in Ember.js and fetch data based on the dynamic segment.

How to define dynamic route handlers in Ember.js?

In Ember.js, dynamic route handlers are defined by using the model hook in the route file. The model hook is used to retrieve data from the server or local storage based on the dynamic segment in the route's URL.

To define a dynamic route handler in Ember.js, you can follow these steps:

1. Create a route file for the dynamic route. For example, if you have a dynamic route for a blog post, you would create a file named app/routes/posts/post.js.
2. In the route file, define the model hook to retrieve the data for the dynamic route. You can access the dynamic segment from the route's params object.

1
2
3
4
5
6

import Route from '@ember/routing/route';

export default class PostsPostRoute extends Route {
  async model(params) {
    const postId = params.post_id;
    return this.store.findRecord('post', postId);
  }
}

1. Use the data retrieved in the model hook to render the template for the dynamic route. You can access the model data in the template.hbs file for the dynamic route.

1
2
3

{{#each model.comments as |comment|}}
  <div>{{comment.text}}</div>
{{/each}}

1. Finally, define the route in your router file (app/router.js) using dynamic segments.

1
2
3
4
5

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

With these steps, you have successfully defined a dynamic route handler in Ember.js that retrieves data based on the dynamic segment in the route's URL.

How to handle errors in dynamic route data fetching in Ember.js?

In Ember.js, you can handle errors in dynamic route data fetching by using the error hook in the route file. Here's how you can handle errors in dynamic route data fetching in Ember.js:

1. Define the model hook in the route file to fetch the dynamic data:

1
2
3
4
5
6
7

import Route from '@ember/routing/route';

export default Route.extend({
  model(params) {
    return this.store.findRecord('model', params.id);
  }
});

1. Add an error hook in the route file to handle any errors that occur during the data fetching:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
15
16
17

import Route from '@ember/routing/route';

export default Route.extend({
  model(params) {
    return this.store.findRecord('model', params.id);
  },
  
  actions: {
    error(error, transition) {
      // Handle the error here
      console.error(error);

      // You can redirect to an error route if needed
      // this.transitionTo('error', error.message);
    }
  }
});

1. If an error occurs during the data fetching process, the error hook will be triggered, and you can handle the error as needed. In the example above, we are logging the error to the console, but you can also redirect to an error route or display an error message to the user.

By using the error hook in the route file, you can effectively handle errors that occur during dynamic route data fetching in Ember.js.

How to use route query parameters with dynamic routes in Ember.js?

In Ember.js, route query parameters can be used with dynamic routes by defining them in the route's model hook and setting them with the transitionToRoute method.

Here is an example of how to use route query parameters with dynamic routes in Ember.js:

1. Define the query parameters in the route file (e.g. app/routes/posts.js):

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13

import Route from '@ember/routing/route';

export default class PostsRoute extends Route {
  queryParams = {
    category: {
      refreshModel: true
    }
  };

  model(params) {
    return this.store.query('post', { category: params.category });
  }
}

1. Update the dynamic route definition in the route file with the query parameter using the transitionToRoute method (e.g. app/routes/posts/detail.js):

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
15

import Route from '@ember/routing/route';

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

  setupController(controller, model) {
    super.setupController(controller, model);

    controller.set('category', this.controllerFor('posts').get('category'));

    controller.transitionToRoute('posts.detail', model.get('id'), { queryParams: { category: controller.get('category') } });
  }
}

1. Access the query parameter in the controller or template file (e.g. app/controllers/posts/detail.js):

1
2
3
4
5
6
7

import Controller from '@ember/controller';

export default class PostsDetailController extends Controller {
  queryParams = ['category'];

  category: null
}

1. Use the query parameter in the template file (e.g. app/templates/posts/detail.hbs):

1
2

<h2>Post Detail</h2>
{{model.title}} - Category: {{category}}

With these steps, you can now use route query parameters with dynamic routes in Ember.js.

How to define default query parameters for dynamic routes in Ember.js?

In Ember.js, default query parameters for dynamic routes can be defined in the route file for that specific route. This can be done by adding a queryParams property to the route definition object.

For example, if you have a dynamic route called posts and you want to define a default query parameter called sortBy with a default value of date, you can do the following:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12

// app/routes/posts.js

import Route from '@ember/routing/route';

export default class PostsRoute extends Route {
  queryParams = {
    sortBy: {
      refreshModel: true,
      defaultValue: 'date'
    }
  };
}

In this example, the queryParams property is an object where the key is the name of the query parameter ('sortBy') and the value is an object with options for that query parameter. The refreshModel: true option specifies that the model should be refreshed when the query parameter changes, and the defaultValue: 'date' option sets the default value for the query parameter.

With this setup, the sortBy query parameter will be available as a property on the controller for the posts route, and will default to 'date' if not specified in the URL.
