Question

我需要在我的User模型中实现一个协议，该协议需要具有一些特殊属性。但是我想避免将它们存储/保存在Realm数据库中。

我没有在文档中看到是否有关键字。有没有办法避免保存一些属性？

public final class User: Object, Mappable, AvatarImageViewDataSource {

dynamic var id: Int = 0
dynamic var desc: String? = nil
dynamic var email: String? = nil
dynamic var firstName: String? = nil
dynamic var lastName: String? = nil

...

public var myPropertyIDontWantToSave: String? = nil // I don't want this to be stored

查看有关Ignoring properties的RealmSwift文档。该部分包含一些示例代码：

class Person: Object {
  dynamic var tmpID = 0
  var name: String { // read-only properties are automatically ignored
    return "\(firstName) \(lastName)"
  }
  dynamic var firstName = ""
  dynamic var lastName = ""

  override static func ignoredProperties() -> [String] {
    return ["tmpID"]
  }
}

境界，避免存放一些财产
