Swift Realm Property’*’已被添加到最新的对象模型MIGRATION中

概述我已经将新的数组属性添加到R​​LMObject和 public class Student: RLMObject { dynamic var id = 0 dynamic var name = "" dynamic var resultList = RLMArray(objectClassName:Result.className())}public class R 我已经将新的数组属性添加到R​​LMObject和

public class Student: RLMObject {    dynamic var ID = 0    dynamic var name = ""    dynamic var resultList = RLMArray(objectClassname:Result.classname())}public class Result: RLMObject {}

错误日志：

Migration is required for object type ‘Student’ due to the following@H_502_7@ errors:@H_502_7@ – Property ‘resultList’ has been added to latest object model.

TRY失败：

let configuration:RLMRealmConfiguration = RLMRealmConfiguration.defaultConfiguration()migration.enumerateObjects(Student.classname()) { oldobject,newObject in    newObject!["resultList"] = RLMArray(objectClassname: Result.classname())}

编辑：

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()

解：

将您的版本更新为1

configuration.schemaVersion += 1

您必须增加schemaVersion并在RLMRealmConfiguration上提供migrationBlock.在那里你可以迁移表.但是你不需要在你的具体情况下.可以自动处理属性的添加.你还需要一个空块.

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