RestKit直接foregin鍵映射

Question

我有以下的JSON

{ 
    ... 
    "users": [ 
      { 
       "name": "Username 1" 
       "id": "uid1", 
      }, 
      { 
       "name": "Username 2", 
       "id": "uid2",     
       "userCreator": "uid1" 
      }, 
      { 
       "name": "Username 3", 
       "id": "uid3", 
       "userCreator": "uid1" 
      } 
     ] 
} 

而在CoreData，在用戶類（屬性名爲id，名）我有類用戶一個一對多的關係命名userCreator

現在我需要映射JSON的關係，我想

RKManagedObjectMapping * mapping = [RKManagedObjectMapping mappingForClass:[User class] inManagedObjectStore:[RKManagedObjectStore defaultObjectStore]]; 

mapping.primaryKeyAttribute = @"id"; 
[mapping mapAttributes:@"id", @"name", nil]; 

RKManagedObjectMapping * userCreatorMapping = [RKManagedObjectMapping mappingForClass:[User class] inManagedObjectStore:[RKManagedObjectStore defaultObjectStore]]; 
userCreatorMapping.primaryKeyAttribute = @"id"; 
[userCreatorMapping mapAttributes:@"id", nil]; 

//[mapping hasOne:@"userCreator" withMapping:userCreatorMapping]; 
[mapping mapRelationship:@"userCreator" withMapping:userCreatorMapping]; 
[mapping connectRelationship:@"userCreator" withObjectForPrimaryKeyAttribute:@"id"]; 

哪個不工作的權利，生產

... 
"users":[{ 
      "id":"uid1", 
      "name":"Username 1" 
     }, 
     { 
      "id":"uid2", 
      "name":"Username 2", 
      "userCreator":{"id":"uid1"} // wanted "userCreator":"uid1", 
     }...

看來違規線

userCreatorMapping.primaryKeyAttribute = @"id"; 
// ... 
[mapping connectRelationship:@"userCreator" 
    withObjectForPrimaryKeyAttribute:@"id"]; 

雖然我不使用RK，似乎很明顯，你講的不是什麼userCreatorMapping映射到什麼。你只是在兩邊給"id"。
