How to Set a Custom Object ID through Cloud Code on Parse.com

When working with the Parse server, particularly with custom object IDs, developers often run into challenges. If you're using Back4App's Parse server and have enabled the option to allow custom IDs, you might think that setting these IDs through Cloud Code is straightforward. However, many find that it doesn't work as expected, leading to errors like "Object not found."

In this guide, we will explore why this happens and the most effective workaround to set custom object IDs using Cloud Code.

Understanding the Error

When you try to set a custom object ID with the following code, you may receive the following error:

This can be frustrating, especially after you’ve enabled the allowCustomObjectId setting in your server's custom settings. So, what's the underlying issue?

The Problem

The problem arises because the traditional method of creating or saving an object with a designated objectId within Cloud Code is not supported. The system expects a unique internal identifier when you create an object, and the automatic assignment of these IDs doesn't align with manually defined ones.

Solution: Using REST API through Cloud Code

Though directly setting a custom object ID in Cloud Code via JavaScript isn't available, there is a workaround. You can achieve this by making a REST API call from within your Cloud Code function.

Step-by-Step Implementation

Here's a step-by-step guide on how to implement this workaround using Cloud Code:

Define Your Cloud Function: Start by creating a Cloud Function which will make the REST API call to set your custom object ID.

Set Up Environment Variables: Make sure to define the required environmental variables in your server's environment file. You need:

APPLICATION_ID

REST_KEY

SERVER_URL

Write Your Cloud Function Code: Here’s a sample implementation:

Breakdown of the Code

Cloud Function Definition: Using Parse.Cloud.define, you create a new function named createObjectId.

Parameters: The function accepts parameters, where you define what class name and property you wish to set.

HTTP Request: It uses Parse.Cloud.httpRequest to send a POST request to the Parse server, effectively creating an object with the custom ID you specify.

Conclusion

By following this method, you can successfully work around the limitations of setting custom object IDs directly through Cloud Code. You take advantage of the flexibility offered by the REST API to achieve your objectives.

Implementing this workaround will help streamline your development process when working with Parse servers, particularly if you are dealing with custom IDs regularly.

Whether you are managing a game score, user profiles, or any other entities in your application, understanding these aspects will empower you to handle data more effectively in your Parse applications.
