WARNING
You probably don't need to use this addon. Most of the use cases you'd use this addon for are perfectly achievable without this addon. Read the following blog post for more info: Ember Best Practices: What are controllers good for?

ember install ember-route-action-helper
The route-action
helper allows you to bubble closure actions, which will delegate it to the currently active route hierarchy per the bubbling rules explained under actions
. Like closure actions, route-action
will also have a return value.
However, returning true
in an action will not preserve bubbling semantics. In case you would like that behavior, you should use ordinary string actions instead.
Usage
For example, this route template tells the component to lookup the updateFoo
action on the route when its internal clicked
property is invoked, and curries the function call with 2 arguments.
{{! foo/route.hbs }}
{{foo-bar clicked=(route-action "updateFoo" "Hello" "world")}}
If the action is not found on the current route, it is bubbled up:
// application/route.js
import Ember from 'ember';
const { Route, set } = Ember;
export default Route.extend({
actions: {
updateFoo(...args) {
// handle action
return 42;
}
}
});
If no action is found after bubbling, an error will be raised. The route-action
also has a return value:
// foo/component.js
import Ember from 'ember';
const { Component } = Ember;
export default Component.extend({
actions: {
anotherAction(...args) {
let result = this.get('updateFoo')(...args);
console.log(result); // 42
}
}
});
You may also use in conjunction with the {{action}}
helper:
<button {{action (route-action 'updateFoo')}}>Update Foo</button>
Compatibility
This addon will work on Ember versions 1.13.x
and up only, due to use of the new Helper
implementation.

Overriding route-action for integration tests
This helper is designed for use in controller templates, not in components. It will not, therefore, resolve route action references in an integration test. If you are using this helper in your components, you can override the helper using a pattern similar to the following:
import { moduleForComponent, test } from 'ember-qunit';
import hbs from 'htmlbars-inline-precompile';
import Ember from 'ember';
moduleForComponent('uses-route-action', 'Integration | Component | uses route action', {
integration: true,
beforeEach(assert) {
this.container
.registry
.registrations['helper:route-action'] = Ember.Helper.helper((arg) => {
return this.routeActions[arg];
});
this.routeActions = {
doSomething(arg) {
return Ember.RSVP.resolve({arg});
},
};
},
});
