Ember如何知道路由模板何时完成加载并触发回调？

Question

Currently working on a chat app with Ember, which is going fantastic as Ember is really nice to work with.

I currently have a chat window, obviously with many lines of people chatting.

I would like to scroll the chat window down on initial page load, here's an example:

<div class="chat-window">
    {{ chat-message username="John Doe" message="Blah" dispic="unknownUser.jpg" }}
</div>

So how might a bind an event to the entire template being loaded (in this case its index.hbs

I know you can do this with components through something like:

import Ember from 'ember';

export default Ember.Component.extend({
  didInsertElement() {
    this.$('.button-collapse').sideNav();
  }
});

Which works fine, so what would the equivalent be for doing it to a template.

As far as I know there is only the index.hbs and index.js route file.

Any information would be great thanks.

Send an action from the component to the route. Route will retrieve data from server and after data is retrieved route will update the data.

Route can handle loading state. ( From Guide )

The code will be something like that:

import Ember from 'ember';

export default Ember.Route.extend({
  chatData:[],
  model:function(){
      return this.get('chatData'); 
  },
  actions:{
      loading:function(){
         //do about loading...
      },
      chatDataRequested:function(){
          retrieveData().then((dataFromServer)=>{this.set('chatData',dataFromServer);});
      }
  }
});
