Ember.js - how to 'get' computed properties

ember.js

Solution

Consider computed properties as properties, not method. Even if they contains a little bit of logic, they really are properties, so you should never call them as a method.

You can access them using the classic `Ember.get` method, as you can see below:

MyApp.myObject = Ember.Object.create({
    name: "foo",
    surname: "bar",
    aComputedProperty: function() {
        return this.get('name') + ' ' + this.get('surname');
    }.property('name', 'surname')
});

MyApp.myObject.get('aComputedProperty'); // => 'foo bar'

You can try this code in this JSFiddle.

Problem

I have successfully created and bound computed properties, but how can I get at them manually in other parts of my code? ``` App.Test = Ember.Object.extend( value: "1" unit: "INCH" display: (-> value = this.get('value') unit = this.get('unit') return "#{value} #{unit}" ).property('value', 'unit') ) ``` How do I call the 'display' method in, say, a controller? The following shows what I thought would work... ``` myTest = App.Test.create() displayValue1 = myTest.get('display') displayValue2 = myTest.display() ``` displayValue1 just returns me an object, not a string. displayValue2 throws a 'no function found" error. So how do I access this property other than a binding?
