Question for BatchUpdateRequest. about coredatastack HOT 7 CLOSED

In a word, I want to be sure what is the correct usage of Batch Request Operations using BigNerdRanch CoreDataStack.
Anyone can help me really appreciated.

Hi @alexiosdev last time I attempted to use the NSBatchUpdateRequest it would only be performed on an NSManagedObjectContext that had a persistent store connected directly to it. i.e. You could not perform batch updates on a child context.

I would guess this is still the case, however this is not documented by Apple.

I'll try to give it a look again in a few days and confirm for sure thats the case.

If that bug is still there, we should definitely document it as a warning note on the related methods in CoreDataStack.

@jeremy-w This doesn't really pertain to any methods in CoreDataStack. This is simply using an NSBatchUpdateRequest on a NSManagedObjectContext.

@rcedwards , Thank you for your time!

Maybe a note on newChildContext()? It's not our code that's broken, but it's a gotcha we can't fix.

Well, I think that's what Apple's Core Data does.
I only had to call reset() on stack.privateQueueContext and stack.mainQueueContext to get changed data.
If you have better idea, I wish you please share with me.
Thanks.
