I have a PFObject
that has an array key. I can successfully call addObject:
on this PFObject
, and can confirm that the object has been added to the array key properly using an NSLog
. However, when I try to save the PFObject
to Parse, even though it says everything went successful, the changes are not shown in the Data Browser.
I have tried everything, and can even get this to work in an older version of my app, but for some reason it will not work anymore.
I posted another StackOverflow question about this here
The only response I got were some comments saying that I should trigger a "before save" function and log everything via Cloud Code. The problem is I don't know javascript, and I've been messing around with Cloud Code and nothing's happening.
Here is the code I am executing in my app:
[self.message addObject:currentUsersObjectId forKey:@"myArrayKey"];
And then I am using saveInBackgroundWithBlock:
I need to alter Cloud Code so that it will check the self.message
object's "myArrayKey"
before saving and log the results.
Edit 2:
Here is how I create currentUsersObjectId:
NSString *currentUsersObjectId = [[NSString alloc]init];
PFUser *user = [PFUser currentUser];
currentUsersObjectId = user.objectId;
Edit 3:
Here is the save block
[self.message saveInBackgroundWithBlock:^(BOOL succeeded, NSError *error) {
if (error) {
NSLog(@"An error has occurred.");
}
}];
Edit 4:
After adding Timothy's cloud code, the saveInBackgroundWithBlock:
now does not successfully complete. Instead an error occurs, and the error object NSLogs as `"Error: Uncaught Tried to save an object with a pointer to a new, unsaved object. (Code: 141, Version: 1.2.17)" and also as:
Error Domain=Parse Code=141 "The operation couldn’t be completed. (Parse error 141.)" UserInfo=0x15dc4550 {code=141, error=Uncaught Tried to save an object with a pointer to a new, unsaved object.} {
code = 141;
error = "Uncaught Tried to save an object with a pointer to a new, unsaved object.";
}
Here is my complete Cloud Code file after adding Timothy's code:
Parse.Cloud.define('editUser', function(request, response) {
var userId = request.params.userId;
//newColText = request.params.newColText;
var User = Parse.Object.extend('_User'),
user = new User({ objectId: userId });
var currentUser = request.user;
var relation = user.relation("friendsRelation");
relation.add(currentUser);
Parse.Cloud.useMasterKey();
user.save().then(function(user) {
response.success(user);
}, function(error) {
response.error(error)
});
});
Parse.Cloud.beforeSave("Messages", function(request, response) {
var message = request.object;
// output just the ID so we can check it in the Data Browser
console.log("Saving message with ID:", message.id);
// output the whole object so we can see all the details including "didRespond"
console.log(message);
response.success();
});
// log the after-save too, to confirm it was saved
Parse.Cloud.afterSave("Messages", function(request, response) {
var message = request.object;
// output just the ID so we can check it in the Data Browser
console.log("Saved message with ID:", message.id);
// output the whole object so we can see all the details including "didRespond"
console.log(message);
response.success();
});

I am adding my own answer in addition to Timothy's in case anyone else is having a problem similar to this. My app uses the following library to allow parse objects to be stored using NSUserDefaults
: https://github.com/eladb/Parse-NSCoding
For whatever reason, after unarchiving the parse objects, they are not able to be saved properly to the Parse database. I had to query the database using the unarchived one's objectId and retrieve a fresh version of the object, and then I was able to successfully make changes to and save the retrieved object.
I have no idea why this is happening now. I have never had any problems until about two weeks ago when I tried to deploy a new version of my cloud code, and if I remember correctly, Parse wanted me to update the Parse SDK or the Cloud Code version before I could deploy it.
These changes must not be compatible with these categories.

After much back and forth, I'm stumped as to why this isn't working for you. As for logging in Cloud Code, if you follow the guide on adding code you can add the following to your main.js and deploy it:
Parse.Cloud.beforeSave("Messages", function(request, response) {
var message = request.object;
// output just the ID so we can check it in the Data Browser
console.log("Saving message with ID:", message.id);
// output the whole object so we can see all the details including "didRespond"
console.log(message);
response.success();
});
// log the after-save too, to confirm it was saved
Parse.Cloud.afterSave("Messages", function(request, response) {
var message = request.object;
// output just the ID so we can check it in the Data Browser
console.log("Saved message with ID:", message.id);
// output the whole object so we can see all the details including "didRespond"
console.log(message);
response.success();
});
With those in place you have plenty of server-side logging that you can check.
