How to execute a function every time an application enters a given route in ember-js

Question

Suppose I have a given ember application

App = Ember.Application.create()

Router

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

How to execute a function every time the application enters the given /: post_id?

Answer 1

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

The activate quota is called on the route each time the route is activated.

Example:

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

Use one of the hooks in the router request life cycle here: http://darthdeus.imtqy.com/blog/2013/02/08/router-request-lifecycle/
