Well, it's time to move my beta testers from 0.1.8 to 0.1.9 and this requires a Core Data database migration. Since the app requires 10.5, I can use Default Automatic Migration. Yippee.
Up to this point, my NSPersistentDocument subclass had used the Persistence Stack which is built into NSPersistentDocument. However, this stack apparently does not create set NSMigratePersistentStoresAutomaticallyOption in its store. It looks to me like I need to override -managedObjectContext and implement "that whole persistence stack enchilada" just to set this one little, commonly-used option. Is there a shortcut? If indeed I need to implement the stack, where is the best place to splice in the pieces? I had been creating new documents from a wizard using -[NSDocumentController openUntitledDocumentAndDisplay:error:], and doing some configuration which required the moc at the end of -init. Now that doesn't work since I can't set a store in new documents before the fileURL has been set, which happens later. I'm imagining many ways to move things around, but I'd like to start out by doing it the *right* way. Sincerely, Jerry Krinock P.S. Sorry if this is in the list archives but since cocoabuilder.com is down I'm searching lists.apple.com. Searching with Search for: NSMigratePersistentStoresAutomaticallyOption Match: All Find: Substring Located In: Whole Document Listname Matches: cocoa-dev I get: Sorry, your search for NSMigratePersistentStoresAutomaticallyOption did not find any results. No documents were found containing "NSMigratePersistentStoresAutomaticallyOption". Seems unbelievable._______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
