如何为嵌套的动态路由渲染ember模板？

// app/router.js
import EmberRouter from '@ember/routing/router';
import config from 'your-app-name/config/environment';

export default class Router extends EmberRouter {
  location = config.locationType;
  rootURL = config.rootURL;
}

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

<!-- app/templates/posts.hbs -->
<h1>Posts</h1>
{{outlet}}

<!-- app/templates/posts/post.hbs -->
<h2>Post {{this.model.id}}</h2>
{{outlet}}

<!-- app/templates/posts/post/comments.hbs -->
<h3>Comments</h3>
{{outlet}}

<!-- app/templates/posts/post/comments/comment.hbs -->
<p>Comment {{this.model.id}}</p>

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

export default class PostsPostCommentsCommentRoute extends Route {
  model(params) {
    return this.store.findRecord('comment', params.comment_id);
  }
}

// 在子路由中
this.modelFor('posts.post').reload();
