DDAU Input Field Pattern

components.input-component.js

import Ember from 'ember';
const {computed} = Ember;

export default Ember.Component.extend({
  
  sourceProperty:null,
  proxyProperty:computed('sourceProperty', {
    get(key){
      return this.get('sourceProperty');
    },
    set(key, value){
      this.get('updateTestProperty')(value);
      return value;
    }
  }),  
});

controllers.application.js

import Ember from 'ember';

export default Ember.Controller.extend({
  appName: 'Ember Twiddle',
  
  testProperty:"initialValue", 
  actions: {
  	updateTestProperty(newValue){
    	this.set('testProperty', newValue);
    }
  }
});

templates.application.hbs

<p>The idea here is to have an input bound to the value of a source property, with the convenience of just setting the `value` of an `input` while using DDAU to a parent to actually do the setting of the property in question.</p>

<h3> Application Template </h3>
testProperty = {{testProperty}}<br>
<hr>
{{input-component updateTestProperty=(action 'updateTestProperty') 
									sourceProperty=testProperty}}
{{outlet}}
<br>
<br>

templates.components.input-component.hbs

<h3> Input Component </h3>

{{input value=proxyProperty}}<br>
proxyProperty = {{proxyProperty}}
{{yield}}
