transitionToRoute('route') From Inside Component - ember.js

Question

How do I transition to a route pragmatically from inside a component action?
I tried to use #get('controller').transitionToRoute('images'), but the controller refers to the component itself. I understand that components should be self contained, so should I be using a view instead to interact with controllers/routes better?
Example
App.ImageEditorComponent = Ember.Component.extend
...
actions:
delete: ->
App.Files.removeObject(object)
#transitionToRoute('images') # This throws an exception
...

Answer 1

You could pass the controller in via a binding and then access it inside your component like so:
{{image-editor currentControllerBinding="controller"}}
App.ImageEditorComponent = Ember.Component.extend
...
actions:
delete: ->
App.Files.removeObject(object)
#get('currentController').transitionToRoute('images')
...

Answer 2

Create action on parent controller.
export default Ember.Controller.extend({
actions: {
transInController() {
this.transitionToRoute('home')
}
}
});
Specify this action on component call.
{{some-component transInComponent=(action "transInController")}}
AFTER v3.4.0 (August 27, 2018)
some-component.js
export default Component.extend({
actions: {
componentAction1() {
this.transInComponent();
}
}
});
OR simpler in some-component.hbs
<button onclick={{#transInComponent}}>GO HOME</button>
BEFORE v3.4.0
Ember.component.sendAction
"Send Action" from component up to controller
export default Ember.Component.extend({
actions: {
componentAction1() {
this.sendAction('transInComponent');
}
}
});

A component is supposed to be isolated from its context, so while you could pass in a reference to the controller, that's probably outside the scope of what a component is for. You might want to just stick with using a view with its own controller instead. Check out Views Over Components - An Ember Refactoring Story.
From Ember.js, Sending Actions from Components to Your Application, there's discussion about sending actions from a component up the route hierarchy.

Answer 4

A lot of things changed in Ember since the original post. So maybe today the best option would be to pass down to the component a route action that takes care of the transition (maybe using the fancy addon ember-cli-route-action.
Otherwise you can create an initializer with ember g initializer router and inside put in there a code like this one
export function initialize (application) {
application.inject('route', 'router', 'router:main')
application.inject('component', 'router', 'router:main')
}
export default {
name: 'router',
initialize
}
This way you can access the router in your component with this.get('router') and, for instance, perform a transition
this.get('router').transitionTo('images')

Answer 5

At component.HBS component file make a
{{#link-to "routeDestinationYouWant" }}
For Example:
<section class="component">
{{#link-to "menu.shops.category.content" "param"}}
<figure id="{{Id}}" class="list-block yellow-bg text-center" {{action "showList" "parameter"}}>
<section class="list-block-icon white-text my-icons {{WebFont}}"></section>
<figcaption class="list-block-title black-text">{{{Title}}}</figcaption>
</figure>
{{/link-to}}
</section>

I've written this answer for another similar question.
If you want to use the router only in a specific component or service or controller, you may try this:
Initialize an attribute with the private service -routing. The - because it's not a public API yet.
router: service('-routing'),
And then inside any action method or other function inside the service or component:
this.get('router').transitionTo(routeName, optionalParams);
Note: It'll be transitionToRoute in a controller.
