Redirect to name

controllers.application.js

import Ember from 'ember';

export default Ember.Controller.extend({
  appName: 'Ember Twiddle'
});

router.js

import Ember from 'ember';
import config from './config/environment';

const Router = Ember.Router.extend({
  location: 'none',
  rootURL: config.rootURL
});

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

export default Router;

routes.my-route.js

import Ember from 'ember';

export default Ember.Route.extend({
  model(params) {
    alert('Model hook should only be called once');

    let model = {
      id: '5',
      name: 'myName'
    };
    
    if (params.id !== model.id) {
     return { redirectTo: model }; 
    }
    
    return model;
  },

  serialize(model) {
    alert('serialize called multiple times :(');
    return { id: model.name };
  },

  afterModel(model) {
    if (model.redirectTo) {
      this.replaceWith('my-route', model.redirectTo);
    }
  }
});

// Questions:
// 1. Why is serialize called multiple times?
// 2. Why does the :id not exist after the redirect?
// 3. Why do we need a redirect for serialize to be called?
// 4. Is there a better way to change the url without copying the model?
