DATASaving stuff in the

var GameScore = Parse.Object.extend("GameScore");var gameScore = new GameScore(); 

 gameScore.set("score", 1337);gameScore.set("player", Parse.User.current());gameScore.set("cheatMode", false);

var GameScore = Parse.Object.extend("GameScore");var gameScore = new GameScore(); 

 gameScore.set("score", 1337);gameScore.set("player", Parse.User.current());gameScore.set("cheatMode", false);

var GameScore = Parse.Object.extend("GameScore");var gameScore = new GameScore(); 

gameScore.save();

 gameScore.set("score", 1337);gameScore.set("player", Parse.User.current());gameScore.set("cheatMode", false);

var GameScore = Parse.Object.extend("GameScore");var gameScore = new GameScore(); 

gameScore.save();

FILESSaving your Pictures in the

HTML

<input type="file" id="profilePhotoFileUpload">

Save a Filevar file = $("#profilePhotoFileUpload")[0].files[0];var name = "photo.jpg";var parseFile = new Parse.File(name, file);parseFile.save(null, {  success: function(parseFile) { profileObject.set("photoFile", parseFile); profileObject.save(); }});

HTML

<input type="file" id="profilePhotoFileUpload">

Save a Filevar file = $("#profilePhotoFileUpload")[0].files[0];var name = "photo.jpg";var parseFile = new Parse.File(name, file);parseFile.save(null, {  success: function(parseFile) { profileObject.set("photoFile", parseFile); profileObject.save(); }});

HTML

<input type="file" id="profilePhotoFileUpload">

Retrieve a File var profilePhoto = profileObject.get("photoFile");$("#profileImg")[0].src = profilePhoto.url();

DATA BROWSERBecause sometimes you just want to see your data

QUERIESGetting stuff from the

var query = new Parse.Query("GameScore");

query.equalTo("player", Parse.User.current());

var query = new Parse.Query("GameScore");

query.equalTo("player", Parse.User.current());

var query = new Parse.Query("GameScore");

query.find();

var query = new Parse.Query(“GameScore");

query.equalTo("player", Parse.User.current());

query.find({  success: function(gameScores) {   // Do something with the returned Parse.Object array  },  error: function(error) {    alert("Error: " + error.code + " " + error.message);  }});

RELATIONSIt’s better together

var user = Parse.User.current();

var user = Parse.User.current();var gameScore = new GameScore();

var user = Parse.User.current();var gameScore = new GameScore();gameScore.set("player", user);

var user = Parse.User.current();

var user = Parse.User.current();var relation = user.relation("friends");

var user = Parse.User.current();var relation = user.relation("friends");relation.add(newFriend);

var user = Parse.User.current();var relation = user.relation("friends");relation.add(newFriend);relation.add(anotherFriend);

var user = Parse.User.current();var relation = user.relation("friends");relation.add(newFriend);relation.add(anotherFriend);user.save();

CLOUD CODEIt’s code in the

Before SaveParse.Cloud.beforeSave("Review", function(request, response) { var comment = request.object.get("comment"); if (comment.length > 140) { // Truncate and add a ... request.object.set("comment", comment.substring(0, 137) + "..."); } response.success(); });

Parse.Cloud.afterSave("Review", function(request) { query = new Parse.Query("Movie"); query.get(request.object.get("movie").id, { success: function(movie) { movie.increment("reviews"); movie.save(); } });});
