How to generate url for a route in Ember.js

问题

I am wondering how is possible to generate url for a given route.

My scenario

I have list of calls (db entity) and user can select several calls and share them with other people via email.

After submition of selected calls is created db row with hash and by relation contains selected calls. Now I need generate link which can be sended by e-mail. This link is not the same route as list of call's route.

So the question is: Is it possible to generate url by route and params in Ember.js? Thank you.

You can use Router#generate which delegates to the router.js library.

Ember 2.5 Example

App = Ember.Application.create();

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

App.Post = Ember.Object.extend();

App.IndexRoute = Ember.Route.extend({
  model: function() {
    return [
      App.Post.create({
        id: 5,
        title: 'I am post 5'
      }),
      App.Post.create({
        id: 6,
        title: 'I am post 6'
      }),
      App.Post.create({
        id: 7,
        title: 'I am post 7'
      })];
  },
  actions: {
    showUrl: function(post) {
      alert(this.router.generate('post.edit', post));
    }
  }
});

Ember 1.3 Example

App = Ember.Application.create();

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

App.Post = Ember.Object.extend();

App.IndexRoute = Ember.Route.extend({
  model: function() {
    return [
      App.Post.create({
        id: 5,
        title: 'I am post 5'
      }),
      App.Post.create({
        id: 6,
        title: 'I am post 6'
      }),
      App.Post.create({
        id: 7,
        title: 'I am post 7'
      })];
  },
  actions: {
    showUrl: function(post) {
      alert(this.router.generate('post.edit', post));
    }
  }
});

This is what the {{#link-to ...}} helper uses under the hood.

回答2:

This can be done in any Ember.js class with the RouterService. It is available since Ember.js 2.15 and in 3.x. Routing functions are no longer confined to Routes.

Ember 2.15, 3.x Example

import Component from '@ember/component';
import { inject as service } from '@ember/service';

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

  actions: {
    showUrl(post) {
      alert(this.get('router').urlFor('post.edit', post));
    }
  }
});
