How to Find Param Of Child Route In Ember.js in 2024?

To find the parameters of a child route in Ember.js, you can access the params property of the model hook within the route definition. This property contains all the parameters passed to the route, including any dynamic segments defined in the route's path. You can then access specific parameters by their key names. Additionally, you can also access the paramsFor method to retrieve parameters from parent routes if needed. By utilizing these built-in features of Ember.js, you can easily find and work with the parameters of child routes within your application.

How to fetch route params in Ember.js controller?

In Ember.js, route params can be accessed in the controller by using the paramsFor() method provided by the Ember object. Here is an example of how to fetch route params in an Ember.js controller:

import Controller from '@ember/controller';
import { inject as service } from '@ember/service';

export default Controller.extend({
  router: service(),

  queryParams: ['param1', 'param2'],

  init() {
    this._super(...arguments);

    let params = this.get('router').paramsFor(this.get('routeName'));
    let param1 = params.param1;
    let param2 = params.param2;

    console.log(param1);
    console.log(param2);
  }
});

In this example, the router service is injected into the controller and the paramsFor method is used to fetch the route params. The param1 and param2 values are accessed from the params object and logged to the console.

It is important to note that the paramsFor method should be called after the init method is called to ensure that the route params have been set properly.

What is the Ember.js route replaceWith method?

The replaceWith method in Ember.js is used to replace the current route with a new route. It navigates to the specified route and replaces the current route in the browser's history stack without adding a new entry. This means that when the user goes back in their browser, they will not return to the previous route, but instead go back to the route before it.

Here's an example of how you can use the replaceWith method in an Ember.js route:

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

export default Route.extend({
  beforeModel() {
    this.replaceWith('new-route');
  }
});

In this example, when this route is entered, it will immediately replace the current route with the 'new-route' without adding a new entry to the browser's history stack.

What is a route param in Ember.js?

A route param in Ember.js is a value passed as a parameter in a route. Route params are specified in the router map and are used to dynamically generate the URL for that route based on the value provided. Route params can be accessed within the route's model hook and are often used to fetch specific data based on the given parameter. For example, a route param could be used to fetch a specific user's data by providing their ID as a parameter in the route URL.

How to pass param to child route in Ember.js?

In Ember.js, you can pass parameters to a child route by using the model hook in the parent route. Here's an example of how you can pass a parameter to a child route:

Define a parent route (e.g., parent-route.js):

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

export default Route.extend({
  model() {
    return {
      parameter: 'value'
    };
  }
});

Define a child route (e.g., child-route.js):

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

export default Route.extend({
  model(params) {
    return params.parameter;
  }
});

Define the router (e.g., router.js):

Router.map(function() {
  this.route('parent-route', function() {
    this.route('child-route', { path: '/:parameter' });
  });
});

With this setup, when you navigate to the child-route, the model hook in the parent-route will pass the parameter to the child-route as a dynamic segment in the URL. The model hook in the child-route can then access and use the parameter passed to it.

What is the Ember.js route transitionTo method?

The Ember.js route transitionTo method is used to programmatically transition to a different route within an Ember.js application. It can be used to navigate to a different route in response to user actions or other events in the application. The transitionTo method takes the name of the route to transition to as an argument, along with any additional parameters that need to be passed to the route.

How to set up controller with route params in Ember.js?

To set up a controller that receives route params in Ember.js, you can use the params object in the model hook of the route to pass the parameters to the controller. Here is an example:

Define a route in your Ember application:

// routes/my-route.js

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

export default Route.extend({
  model(params) {
    return {
      param1: params.param1,
      param2: params.param2
    };
  }
});

Define a controller for the route:

// controllers/my-route.js

import Controller from '@ember/controller';

export default Controller.extend({
  // Any controller logic here
});

In your template, you can access the route params through the controller:

// templates/my-route.hbs

{{model.param1}}
{{model.param2}}

This way, you can set up a controller that receives route params in Ember.js.
