I'm trying to do a batch update and I'm not getting an exception, but it's telling me 0 records are updated. If I run the following code
let request = NSBatchUpdateRequest(entityName: "Order")
request.predicate = NSPredicate(format: "sql_ident IN %@", completed)
request.propertiesToUpdate = ["complete" : true]
request.resultType = .UpdatedObjectsCountResultType
do {
let res = try moc.executeRequest(request) as! NSBatchUpdateResult
print("Set \(res.result!) objects to complete (should be \(completed.count))")
} catch let error as NSError {
print("Error: \(error.localizedDescription)")
}
let r = NSFetchRequest(entityName: "Order")
r.predicate = NSPredicate(format: "sql_ident IN %@", completed)
let count = moc.countForFetchRequest(r, error: nil)
print("I found \(count) orders")
Then I get this output:
Set 0 objects to complete (should be 6470)
I found 6470 orders
So it's definitely seeing the objects I expect it to, but it's not updating any of them. What am I doing wrong here?
If it makes any difference, this is in a child context
