kalyco / ember order of operations

Created June 9, 2015 17:55

Ember's order of operations

	1. User hits a URL
	2. Ember's Router recognizes it and passes it to a Route object
	3. The Route sets up a Controller and supplies it with a Model
	4. The Model provides the View layer (represented by a Template) access to the data
	5. Any properties defined by the Model are available to the Controller
	ex: if User has first_name, your template has direct access to it through the Controller

	* don't need to define an empty controller method like in Rails *
	* Ember will also generate the controller for you if one does not exist *

Binds the field to a property in the controller and lets Ember handle keeping things updated. In this example a controller is set up with 2 properties 'number' and 'timesTwo'

	// in the controller
	App.NumberController = Ember.ObjectController.extend({
	number: 1,
	timesTwo: function() {
	return Number(this.get('number')) * 2;
	}.property('number') //tells it to treat it as a dynamic property that updates whenever number updates.
	});

	//in the template
	{{input type="text" value=number size=50}} x2 = {{timesTwo}}

kalyco / ember view

Created June 9, 2015 16:05

View main function: 1. Creating reusable components. 2. Setting up logic to handle events

	App.ProfilePhotoView = Ember.View.extend({
	click: function(evt) {
	this.get('controller').send('ExpandProfilePhoto');
	}
	});

	App.UserController = Ember.ObjectController.extend({
	actions: {
	expandProfilePhoto: function() {
	//get the expanded picture and display it

kalyco / ember controller

ember controllers are different from rails controllers in that their primary function is to provide the logic to access data from the model. In this example, the user has different first_name, last_name properties, but wants to show a full name. This is something that a controller would be used for.

	App.UserController = Ember.Object.Controller.extend({
	fullName: function() {
	return this.get("first_name") + " " + this.get("last_name");
	}
	})

kalyco / ember model hook

Created June 9, 2015 14:03

In ember first create the route object, then use the model hook to get the data you need from it.

	App.UserRoute = Ember.Route.extend({
	model: function(params) {
	return this.store.find(user, params.user_id);
	}
	)};
