Parse.com to Mongodb migration: PFRelation doesn't work

I succeeded to migrate my app database, but my Xcode code doesn't work with the new database automatically migrated. On parse db, I had table "User" with "friends" relationship.

When I migrated Parse data to Heroku with MongoLab, I have a joined table "friends:_User"

But when I log on simulator:

self.currentUser = [PFUser currentUser];

self.friendsRelation = [[PFUser currentUser] objectForKey:@"friends"];

NSLog(@"%@", self.currentUser);

NSLog(@"%@", self.friendsRelation);

friendsRelation (PFRelation) returns null:

2016-02-28 23:29:21.785 ChillN[4281:59046] <PFUser: 0x7fa43c09ed20, objectId: MZdPHaqByR, localId: (null)> { phone = "000000"; surname = a; username = a; }

2016-02-28 23:29:21.786 ChillN[4281:59046] (null)

That works as expected with Parse, so how can I change this without changing my code? Is it possible? if this isn't the case, what I've to change in my code?

Just change:

self.friendsRelation = [[PFUser currentUser] objectForKey:@"friends"];

to

self.friendsRelation = [[PFUser currentUser] relationForKey:@"friends"];
