Generated Objects
As explained in the routing guide, whenever you define a new path in your router, Ember.js attempts to find a corresponding route, controller, and template, each named according to naming conventions. If an implementation of any of these objects is not found, appropriate objects will be generated for you.
Generated routes
Given you have the following route:
Router.map(function() {
this.route('posts');
});
When you navigate to /posts, Ember.js looks for route:posts.
If it doesn't find it, it will automatically generate route:posts for you.
Generated Controllers
If you navigate to route posts, Ember.js looks for a controller called controller:posts.
If you did not define it, one will be generated for you.
Generated Templates
A route also expects a template. If you don't provide a template, an empty one will be generated for you.
The empty template includes an {{outlet}}, so nested routes will
render correctly even if the route does not explicitly provide a
template.
