Should not use needs to load other controllers JS-0770
Bug risk
Minor
ember
Avoid using needs to load other controllers. Inject the required controller instead. needs was deprecated in ember 1.x and removed in 2.0.
Bad Practice
export default Controller.extend({
needs: ['comments'],
newComments: alias('controllers.comments.newest')
});
Recommended
import Controller, { inject as controller } from '@ember/controller';
export default Component.extend({
comments: controller(),
newComments: alias('comments.newest')
});
