AngularJS - RESTful CRUD with Services and $http

gistfile1.js

//
// CRUD API for RESTful services with URLs similar 'http://services.mysite.com/classes/Book'.
//
// e.g.   parse.get(
//				"Book",
//				123,
//				function(response){ console.log(response.toString());}
//			);
//
services.factory('parse', function($rootScope, $http) {
	var parseUrl = "http://services.mysite.com";

	return {
		//Create a db object on server
		create: function(className, data, callback) {
			$http.post(
				parseUrl+'/classes/'+className,
				data,
				{ headers: parseHeaders }
			)
			.success(function(response) {
				forge.logging.log("added object successfully!");
				$rootScope.$apply(function() { callback(null, response); });
			})
			.error(function(response) {
				forge.logging.log("error adding object!");
				$rootScope.$apply(function() { callback("Cannot submit data!"); });
			});
		},
		//Get a db object by id
		get: function(className, objectId, callback) {

			$http.get(
				parseUrl+'/classes/'+className+'/'+objectId,
				{ headers: parseHeaders }
			).success(function(response) {
				$rootScope.$apply(function() { callback(null, response); });
			}).error(function(response) {
				$rootScope.$apply(function() { callback(response.error || "Cannot get object "+className+"/"+objectId+"!"); });
			});
		},
		//Get a list of db objects with query
		query: function(className, query, callback) {
			var config = { headers: parseHeaders };
			if (query) config.params = { where: query };
			$http.get(
				parseUrl+'/classes/'+className,

			}).error(function(response) {
				$rootScope.$apply(function() { callback(response.error || "Could not query "+className+"!"); });
			});
		},
		//Remove a db object
		remove: function(className, objectId, callback) {
			$http['delete']( //['delete'] to get around using delete js keyword
				parseUrl+'/classes/'+className+'/'+objectId,
				{ headers: parseHeaders }
			).success(function(response) {

on line 54.. did not get why 'd' is used... seems to be a typo error.

Yeah, it most likely is a typo...

parseURL and parseUrl.
