How to invoke an action in the current router from the child component in Ember Octane?

Question

I am working with Ember Octane version, I want to invoke an action in the Route from the child component. The pseudo code is as follows.

 **Route** export default class SomeRouter extends Route { model() { return data; } @action refreshRoute() { this.refresh(); } } **SomerRouter.hbs** <ChildComponent> //Using child component here **ChildComponent** export default class ChildComponent extends Component { @action revert() { //How do I invoke the "refreshRoute" on the SomeRouter from here? } }

In the revert method of the above child component, "this" refers to the component itself but in the previous version of the ember "this" refers to the router where I could simply call this.refresh(). So how do I achieve this in Ember Octane. Would really appreciate any help.

You dont. This is actually one of the things that are still a bit inconsistent even with octane. Because the bound context of the route template is the Controller , not the route. So you can not access the action with {{this.refreshRoute}} .

To call an action on the Route your best way is to uzilize send . But to do this you need a Controller and define a different action on the Controller:

controllers/some.js :

export default class SomeController extends Controller {
  @action
  refreshRouteFromController() {
    this.send('refreshRoute');
  }
}

Now this function you can use from your template:

<ChildComponent @refresh={{this.refreshRouteFromController}}>

And then use it from your component:

revert() {
   this.args.refresh();
}

Or directly from a button:

<button {{on "click @refresh}}>...</button>
