Ember js use handlebars helper inside a controller?

Question

I have a helper method that maps a number to a text -

Ember.Handlebars.helper('getStatusText', function (value, options) {
    switch(value) {
        case 1: return "Fresh";
            break;
        case 2: return "Callback";
            break;
        default: return "Unable to get Status";
    }
});

I am able to use the helper in the view by using {{getStatusText 1}}

But how do I use the helper in an action inside an ObjectController ?

Test.DealController = Ember.ObjectController.extend({

    selectedStatusType: null,
    statusList: ["Fresh","Callback"],

    actions: {
        updateStatus: function(deal) {
// How do I call the handlebars helper here ?
            console.log({{getStatusText 1}});
        }
    },

});

this obviously does not work.

What are the other ways ??

For better understanding, here is the jsbin

Answer 1

With ember-cli it can be done like this:

// helpers/foo.js
export function foo(params) {
    return params;
}
export default Ember.Helper.helper(foo);

Helper foo exports a function (containing the helper logic) and the function wrapped in an Ember helper (for use in a template).

// helpers/bar.js
import { foo } from '<project>/helpers/foo';
export function bar(params) {
    return foo(params);
}
export default Ember.Helper.helper(bar);

Helper bar imports the helper function from foo and uses it in it's own template helper.

Pull the logic out of the helper, making it available to be called both by the helper, and by non handlebars helper items alike. Parsing it into handlebars template and evaluating it is over complicating it.

Where you put it is up to you, you could namespace it to your app, or just create it as a function that lives with your helper.

function getStatusText(value){
    switch(value) {
        case 1: return "Fresh";
            break;
        case 2: return "Callback";
            break;
        default: return "Unable to get Status";
    }
}

Ember.Handlebars.helper('getStatusText', function (value, options) {
  return getStatusText(value);
});
