I am currently trying to render out this json object in a ul. I'd like to be able to cycle through the GamesList and get the games and their attributes in a list. I've kinda hit a wall where I am not entirely sure how to accomplish this. Still very new to backbone so any help would be greatly appreciated.
JSON Object:
{
"GamesList":[
{
"Date":"2013/07/02",
"Games":[
{
"Id":"3252",
"Time":"12:10 AM"
}
]
},
{
"Date":"2013/07/02",
"Games":[
{
"Id":"3252",
"Time":"12:10 AM"
}
]
},
{
"Date":"2013/07/02",
"Games":[
{
"Id":"3252",
"Time":"12:10 AM"
}
]
}
]
}
App Structure:
App.Models.Game = Backbone.Model.extend({
defaults: {
GamesList: ''
}
});
App.Collections.Game = Backbone.Collection.extend({
model: App.Models.Game,
url: 'path/to/json',
parse: function (response) {
return response;
}
});
App.Views.Games = Backbone.View.extend({
tagName: 'ul',
initialize: function () {
this.collection = new App.Collections.Game();
this.listenTo(this.collection, 'reset', this.render, this);
this.collection.fetch();
},
render: function () {
//filter through all items in a collection
this.collection.each(function (game) {
var gameView = new App.Views.Game({
model: game
});
this.$el.append(gameView.render().el);
}, this)
return this;
}
});
App.Views.Game = Backbone.View.extend({
tagName: 'li',
template: _.template($('#gameTemplate').html()),
render: function () {
this.$el.html(this.template(this.model.toJSON()));
return this;
}
});
var gameCollection = new App.Collections.Game();
gameCollection.fetch({
data: {
collection_id: 25
},
success: function (data, textStatus, jqXHR) {
console.log(data);
console.log(textStatus);
console.log(jqXHR);
console.log('success');
},
error: function () {
alert('Oh noes! Something went wrong!')
}
});
var gamesView = new App.Views.Games({
collection: gameCollection
});
$(document.body).append(gamesView.render().el);

I'm seeing a little confusion in it. Let's proceed step by step:
--------- AFTER COMMENT ---------
You can set your model as:
defaults: {
Date:'',
Games:''
}
then modifying your parse function as
parse: function (response)
{
var _this = this;
_.map(response, function(obj) {
_this.add(obj)
});
}
This way you add each single item in the collection as your model expect.
Another problem I'm seeing is that you're creating and fetching the collection twice:
...
this.collection = new App.Collections.Game();
this.listenTo(this.collection, 'reset', this.render, this);
this.collection.fetch();
...
and then
var gameCollection = new App.Collections.Game();
...
gameCollection.fetch({
data: {
....
...
var gamesView = new App.Views.Games({
collection: gameCollection
});

It looks like your JSON object is not inlined with Backbone.Collection...
as you declared App.Collections.Game
has url /path/to/json
which means the json that needs to return is a list... without the GamesList
that is seen in your JSON
EDIT:
You can use the parse function in your Games Collection to fix the json retrieved from your server
parse:function(response){
return response.GamesList;
}
Important: Please note that your json objects that are fetched from the server should have ID. Backbone will 'think' these models are new and will create them upon save...
