Backbone P2 - CodeSchool

/* Code school Snippets - Backbone part 2 */

/* 1. More Models */

// parsing data that comes in differently - through parse function

var Appointment = Backbone.Model.extend({
  parse: function(response){
		return response.appointment;
  }
});

// change attributes and set id
// "appointment": { "title": "Ms. Kitty Hairball Treatment", "cankelled": false, "identifier": 1 }

var Appointment = Backbone.Model.extend({
  idAttribute: 'identifier',
  
  parse: function(response){
    var appointment = response.appointment;
    appointment.cancelled = appointment.cankelled;
    delete appointment.cankelled;
    return appointment;
  }
});

// force the parsing
var appointment = new Appointment(data, {parse: true});

// toJSON no longer works on templates
var AppointmentView = Backbone.View.extend({
  template: _.template('<span>' +
                        '<%= title %></span>' +
                        '<a href="#">x</a>'),

  render: function(){
	this.$el.html(this.template(this.model.attributes));
    return this;
  }
});

/* 2. Collections */
// tels also about pagination but a bit unclear how to implement that yet

// Use Comparators to sort data 
var TodoItems = Backbone.Collection.extend ({
	comparator: ‘status’
});

// Comparator as function -- sort status in reverse order
var TodoItems = Backbone.Collection.extend ({
	comparator: function(todo1, todo2) {
		return todo1.get('status') < todo2.get('status');
	}
});

// get length of items
var TodoItems = Backbone.Collection.extend ({
	completedCount: function () {
		return this.where({status: 'complete'}).length;
	}
})

// fetch data using parameters -- creates url like /appointments?since=2013-01-01&per_page=10
var appointments = new Appointments();
appointments.fetch({data: {since: "2013-01-01", per_page: 10}});
