Backbone+Parse.com Collection.fetch() returns empty array using event callback
问题 i'm starting using parse.com to develop a web app but i'm stuck on a simple problem. I defined a model (or object in Parse SDK) as: Book.Model = Parse.Object.extend("book", { // Default attributes for the book. defaults: { title: "placeholder...", }, // Ensure that each book created has `title`. initialize: function() { if (!this.get("title")) { this.set({"title": this.defaults.title}); } }, }); and a collection: Book.List = Parse.Collection.extend({ // Reference to this collection's model.
