How to bulk update a set of objects matching a query

#1

Is there a way to update objects that satisfy a query without having to retrieve the objects then save them individually?
Example:
Object foo - {a: number}
Desired:
query - {a: 10}
Update foo, set a = 0 for matching objects.
Thanks.

I don’t think there is a way to do this. You have to retrieve objects first.

Since Parse server got some hook functions like before and after save, it do not support currently this type of update.
If you need to update a lot of objects you can use the .each on a Parse query.

@uzaysan, @Moumouls,
Thank you guys. I think I will use .each.

You can use Query.eachBatch and then saveAll to save them by batch.
