Setting a specific key of an Object-type column

[zartre]

Is there a way to set a specific key of a column with type Object? I've been trying the code below with no success:

user.set('achievements.firstGame', true);

However, setting it with a whole object works fine.

const achm = { firstGame: true };
user.set('achievements', achm);

@flovilmart thats a good feature?! I believe it's a good thing. If ok, I can implement this.

[flovilmart]

Not sure it’s a good feature, nor how it will be implemented server side. So if you want this feature use the mongo driver directly.

@flovilmart I think this would be a great feature, it would also be an atomic operation and mongo / postgres can support it

[flovilmart]

Well it’s probably a confusing one as it’s an atomic update. Unlike increment, if the object is not realized locally,it can backfire.

Again, I don’t believe the job of the SDK is to expose all single mongo and oostges feature but to provide a simple access to the most common ones to enable fast and reliable mobile and web app developments.

You’re free to challenge me and tell me it’s one of the top important things, I just don’t see it this way. For example, push notifications scalability, graphql, more Db adapters would be higher on my list :)

@dplewis @flovilmart so I understood the feature is just a way to set objects and would not change anything server and client. As an example, he even showed that he only wants to be able to set an object with dot notation.

@DobaKung am I wrong?

[flovilmart]

It’s not just about allowing dot notation. Then you need atomic updates in bot oh and mongodb, and posssivly all DB adapters. This is a very low hanging fruit,I mean, I your ‘need’ this, why not use mongo directly? Or mongoose? At one point if the parse SDK is simply a transform over the mongodb query language, whst’s The point?

[zartre]

Actually my intent was that there should be a way to set just specific data (key) that has a change. Say, a user has achievements object: { cats: 10, dogs: 6 }. When cats has an update, there should be a way to just set cats without the need to set the entire achievements object. Or did I miss anything? Very new to Parse.

[flovilmart]

Perhaps you should consider another mechanism. Nesting documents is likely a bad design example, and likely you should use multiple classes and objects

I was updating my MySQL adapter and accidentally added this. Surprised that this didn’t work for Postgres out of the box.

If anybody is interested this functionality already exists.

Pass in ignoreValidation to set options.

set(key, value, { ignoreValidation: true });
