Backbone underscore where inside json - json

Question

I have an app in backbone where I want to find inside a Json record where hotel_id = 1 for example.
I have done in this mode:
var Room = Backbone.Model.extend();
var Rooms = Backbone.Collection.extend({
model:Room,
url : "includes/rooms.json"
});
var RoomView = Backbone.View.extend({
template: _.template($("#hotel-list-template").html()),
initialize: function(){
this.render();
},
render: function(){
this.bindRoomToHotel();
var element = this.$el;
element.html('');
// $(this.el).html(this.template({hotels: this.collection.models}));
},
bindRoomToHotel: function() {
allRooms = new Rooms();
allRooms.fetch();
rooms = allRooms.where({'hotel_id' : 1});
console.log(rooms);
}
});
I have cut many parts but the problem is inside bindRoomHotel when I make the where function return me empty.
This is my json:
[
{
"id" : "r1",
"hotel_id" : "1",
"name" : "Singola"
},
{
"id" : "r1_1",
"hotel_id" : "1",
"name" : "Doppia"
},
{
"id" : "r2",
"hotel_id" : "2",
"name" : "Singola"
},
{
"id" : "r2_1",
"hotel_id" : "2",
"name" : "Tripla"
}
]
How to find record with hotel_id=1?

Answer 1

Pretty sure you don't need quotes round the attribute name, maybe try this
rooms = allRooms.where({ hotel_id : 1 });
edit: I don't see where you are initializing those objects in the code you have provided, i'd expect to see something like this.
var Room = Backbone.Model.extend();
var Rooms = Backbone.Collection.extend({
model: Room,
url: "includes/rooms.json"
});
var RoomView = Backbone.View.extend({
template: _.template($("#hotel-list-template").html()),
initialize: function () {
this.render();
},
render: function () {
this.$el.html(_.template(this.template, this.collection.where({ hotel_id: 1 }));
}
});
var roomsCollection = new Rooms();
var roomView;
roomsCollection.fetch({
success: function ( rooms ) {
roomView = new RoomView( collection: rooms );
}
});
