In order to map URLs to routes we have an object called the Router:Įxport default class PostsPostRoute extends Route ) A tag cloud on that same page loaded by another service would be considered secondary data and shouldn't belong to the URL. For example, a page displaying comments for blog post with ID=5 could naturally have a URL of. It represents the state of the current page's primary data. See the diagram above – everything starts at the URL. The URL is a first-class citizen in Ember. Great! Now that we understand the flow of a basic application, it's time to dive deeper. Once its value is returned or its promise resolved, the result will be set in the model property of the controller/template. model: the property on the controller/template.Generally, any time a URL is requested by the browser model() will be called.
