Creating a replica of a Parse Server object

I've been struggling to clone Parse objects without affecting the original ones. Despite trying various methods like Parse.Object.clone() and converting to JSON, I haven't found a working solution. I came across some recommendations online but none of them provided a real fix.

Is there really no reliable way to create separate clones of Parse objects with independent attributes?

My goal is to implement a 'cancel changes' button that reverts back to the cloned versions without saving any modifications.

Answer №1

Parse.Object.clone provides a shallow copy. To create a deep copy (independent objects), I have developed and utilized the following code snippet:

var originalObject = ...
var objectJSON = originalObject.toJSON();
delete objectJSON.objectId; // Ensure it is treated as a new DB object when saved
var duplicate = new Parse.Object( object.className );
duplicate.set( objectJSON );

I personally feel that having a Parse.Object.deepClone method would be quite beneficial...

Answer №2

Have you tried using Parse.Object.clone() to achieve the desired outcome? It seems like that function should work for your needs.

In the iOS (and possibly android) SDK, there is a revert method available for objects which allows them to be reset to their last saved or fetched state.

It's important to remember that in JavaScript, passing objects into functions treats them as pass by reference, meaning changes made within a function will affect the original object. This can be both useful and frustrating at times.

If Parse.Object.clone() is not providing the solution you need, my suggestion would be to manually create a new object shell and fetch it or query for the object if including additional data is necessary when resetting the data.
