      });

    });

    import Route from '@ember/routing/route';
    
    export default PostRoute extends Route {
      model({ postId }) {
        // Post will be accessible as `this.model` in the controller
        // or `{{@model}}` in the template.
        return this.store.find('post', postId);
      }
    }

    import Component from '@glimmer/component';

      get fullTitle() {
        return `Post: ${title}`;
      }
      
      titleUpdate(event) {
        this.title = event.target.value;
      }
    }
