Reference to entity name in NSPredicate?

Subject: Reference to entity name in NSPredicate?
From: Z Rosen <email@hidden>

I have three entities (red_folder, green_folder and blue_folder) that all descend from a single parent entity (folder). I have a NSArrayController (allMyFolders) who's entity is set to 'folder'. It lists all of the red_ green_ and blue_ folders. All is good.

Now, say I want to exclude the blue_ folders. It would be nice if I could just say:

NSPredicate *blueFolderPredicate = [ NSPredicate predicateWithFormat:@"entity.name LIKE %@", @"blue_folder" ]; [ allMyFolders setFetchPredicate:[ NSCompoundPredicate notPredicateWithSubpredicate:blueFolderPredicate ] ];

... but (of course) entity is not a valid key.


Any ideas?
