解析Heroku遷移（MongoLab）：PFRelation issue

我成功地將parse遷移到parse-server和mongolab。現在一切都按預期工作，除了當我用MongoLab記錄PFUser時，我的PFRelation對象始終爲空。解析Heroku遷移（MongoLab）：PFRelation issue

在我的AppDelegate，當我運行這段代碼（官方解析）：

[Parse setApplicationId:@"xxxxxx" 
       clientKey:@"xxxxxx"]; 
[PFUser enableRevocableSessionInBackground];

HomeView.m：

self.currentUser = [PFUser currentUser]; 
self.friendsRelation = [[PFUser currentUser] objectForKey:@"friends"]; 
NSLog(@"%@", self.currentUser); 
NSLog(@"%@", self.friendsRelation);

登錄後，我HomeView記錄此：

2016-02-28 23:25:38.756 ChillN[4131:57119] <PFUser: 0x7fe0b3e4fc10, objectId: MZdPHaqByR, localId: (null)> { 
    friends = "<PFRelation: 0x7fe0b3e4f900, 0x7fe0b3e4fc10.friends -> _User>"; 
    phone = "06 19 05 39 30"; 
    surname = a; 
    username = a; 
} 
2016-02-28 23:25:38.756 ChillN[4131:57119] <PFRelation: 0x7fe0b3e4f900, 0x7fe0b3e4fc10.friends -> _User>

所以一切都是正確的。

與mongolab分貝

現在：

的AppDelegate：

[Parse initializeWithConfiguration:[ParseClientConfiguration configurationWithBlock:^(id<ParseMutableClientConfiguration> configuration) { 
    configuration.applicationId = @"xxxxxxx"; 
    configuration.clientKey = @"xxxxxxx"; 
    configuration.server = @"http://xxxxxxx.herokuapp.com/parse/"; 
}]];

我登錄後，我HomeView記錄此：

2016-02-28 23:29:21.785 ChillN[4281:59046] <PFUser: 0x7fa43c09ed20, objectId: MZdPHaqByR, localId: (null)> { 
    phone = "06 19 05 39 27"; 
    surname = a; 
    username = a; 
} 
2016-02-28 23:29:21.786 ChillN[4281:59046] (null)

對於記錄，我只是用：

[PFUser logInWithUsernameInBackground:user 
           password:password block:^(PFUser *user, NSError *error) {}];

這裏是我的DB：解析：

的Heroku（MongoLab）：

這裏是MongoLab對用戶的記錄：

{ 
    "_id": "MZdPHaqByR", 
    "_perishable_token": "SHuhtWl0EoxxmNLOkspmp1vBF", 
    "username": "a", 
    "phone": "06 19 05 39 27", 
    "surname": "a", 
    "_session_token": "zO2drjzrO0To1q0JiohaL8f4v", 
    "_hashed_password": "$2a$10$a7j5yB7uFDtv.YnHESVJgO9Io.nci8hbx7vngOo.FyzA3qBLxw38G", 
    "_created_at": { 
     "$date": "2016-02-28T21:55:48.548Z" 
    }, 
    "_updated_at": { 
     "$date": "2016-02-28T22:03:45.704Z" 
    } 
}

這是我的代碼只是一個錯誤，我必須更換：

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

到

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

希望能幫助到另一個。乾杯!
