How to execute a function every time the app enters a given route in ember-js

Question

Suppose I have got a given ember application

App = Ember.Application.create()

A router

App.Router.map(function() {
  this.resource("posts", function() {
    this.resource("post", {
      path: "/:post_id"
    })
  });
});

How do I execute a function each time whenever the application enters a given /:post_id ?

You can implement App.PostRoute to specify your custom behavior for your post route. If you don't, Ember will create this class behind the scenes.

The activate hook is called on the route every time the route is activated.

Example:

App.PostRoute = Ember.Route.extend({
  activate: function() {
    doSomething();
  }
});
