Error inserting new relation #51

Open callzhang opened 10 years ago

callzhang commented 10 years ago

In Basic Example, I added a new Artist object with relation to Song, which also has relation to Genre:

Artist *artist = [NSEntityDescription insertNewObjectForEntityForName:@"Artist" inManagedObjectContext:context];
Song *song = [NSEntityDescription insertNewObjectForEntityForName:@"Song" inManagedObjectContext:context];
Genre *genre = [NSEntityDescription insertNewObjectForEntityForName:@"Genre" inManagedObjectContext:context];
artist.artistName = @"New";
genre.genreName = @"My genre";
song.songTitle = @"Song title";
song.songArtist = artist;
song.songGenre = genre;
NSError *err;
[context save:&err];
if (err) {
    NSLog(@"%@", err.description);
}

But the IncrementalStore threw an error as follows. What's rather interesting is that the code works sometime and doesn't work some other times. I tried to delete the relation definition on Parse.com and it still works. It seems that the framework doesn't use relation definition on Parse to get the related item.

@callzhang Did you discover a way to fix this? Experiencing the same issue with the Basic Example + MagicalRecord Example apps.

@sbonami Curious if you have any thoughts too...

callzhang commented 10 years ago

@luke0x I pretty much fixed it on my last pull request. Since @sbonami provided me the admin rights, I haven't had a chance to get out of my daily work but I have some plan to do it very soon.

@callzhang Nice, I'll take a look. Thanks for getting back.
