斯威夫特域屬性「*」已經被添加到最新的對象模型遷移

Question

我已經添加了新的數組屬性的RLMObject和

public class Student: RLMObject { 
    dynamic var id = 0 
    dynamic var name = "" 
    dynamic var resultList = RLMArray(objectClassName:Result.className()) 
} 

public class Result: RLMObject { 
} 

錯誤日誌：

遷移所需的對象類型「學生'由於以下原因 錯誤： - 屬性'resultList'已被添加到最新的對象模型。

TRY失敗：

let configuration:RLMRealmConfiguration = RLMRealmConfiguration.defaultConfiguration() 

migration.enumerateObjects(Student.className()) { oldObject, newObject in 
    newObject!["resultList"] = RLMArray(objectClassName: Result.className()) 
} 

編輯：

let configuration:RLMRealmConfiguration = RLMRealmConfiguration.defaultConfiguration() 
    print("Realm db current version: \(configuration.schemaVersion)") 
    configuration.schemaVersion = 1 
    configuration.migrationBlock = {(migration:RLMMigration, oldSchemaVersion: UInt64) in 
     print("Realm db migration start") 
     if oldSchemaVersion < 1 { 
      print("Schema version: 1 - Rename fields") 
      migration.enumerateObjects(Student.className()) { oldObject, newObject in 
       newObject!["creationDate"] = oldObject!["createdAt"] 
       newObject!["modifiedDate"] = oldObject!["updatedAt"] 
      } 
     } 
     print("Realm db migration finish") 
    } 
    RLMRealmConfiguration.setDefaultConfiguration(configuration) 
    let realm = RLMRealm.defaultRealm() 

SOLUTION：

更新您的版本，以+1

configuration.schemaVersion += 1 

Answer 1

您必須增加您的schemaVersion並在您的RLMRealmConfiguration上提供migrationBlock。在那裏你可以遷移表格。但在這裏你並不需要你的具體情況。屬性的添加可以自動處理。你仍然需要一個空白塊。

let config = RLMRealmConfiguration.defaultConfiguration() 
config.schemaVersion = 1 
config.migrationBlock = { (migration, oldSchemaVersion) in 
    // nothing to do 
} 
RLMRealmConfiguration.setDefaultConfiguration(config)
