相关疑难解决方法(0)

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:

由于以下错误,对象类型'Student'需要迁移: - 属性'resultList'已添加到最新的对象模型中.

尝试失败:

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 …

当我调试应用程序时，我添加了一个新属性（@property NSString *haha;），但它显示以下异常：

Terminating app due to uncaught exception 'RLMException', reason: 'Migration is required due to the following errors: 
- Property 'haha' has been added to latest object model.'

但是当我添加忽略的属性时，它工作得很好：

+ (NSArray *)ignoredProperties {
    return @[@"thead"];
}

为什么？谢谢。
