来自Realm对象的用户具有相同的主键领域 [英] User made from Realm object has same Primary Key Realm

问题描述

我正在尝试使用真实的模型制作用户个人资料，这是下面的模型:

Im trying to use a real model to make a user profile, here is the model below:

class UserProfile: Object {
dynamic var id = UUID().uuidString
dynamic var name:String = ""
dynamic var age = ""
dynamic var email = ""
dynamic var userName = ""
dynamic var passWord = ""

override static func primaryKey() -> String? {
    return "id"
}

}

我正在通过IBAction按钮将对象添加到默认领域文件中，如下所示:

I'm adding objects to the default realm file via an IBAction button as shown here:

@IBAction func signUpButton(_ sender: UIButton) {



    try! realm.write {

    user.userName = userNameTextField.text!
    user.passWord = passWordTextField.text!
    user.email = emailTextField.text!
    user.name = fullNameTextField.text!
    user.age = ageTextField.text!
    user.id = UUID().uuidString

    realm.add(user)

    }
    userQuery()
}

问题在于创建的用户对象具有相同的"id"/主键:

The issue is that the created user objects have the same "id"/Primary key:

简·韦尔戈(Jane Vergo)今年17岁，ID:A6A67E2D-C9A9-4D6B-815C-27BC22B3089B

Jane Vergo is 17 years old ID: A6A67E2D-C9A9-4D6B-815C-27BC22B3089B

Jake Lawson今年19岁，ID:A6A67E2D-C9A9-4D6B-815C-27BC22B3089B

Jake Lawson is 19 years old ID: A6A67E2D-C9A9-4D6B-815C-27BC22B3089B

卢克·凯奇(Luke Cage)20岁，ID:A6A67E2D-C9A9-4D6B-815C-27BC22B3089B

Luke Cage is 20 years old ID: A6A67E2D-C9A9-4D6B-815C-27BC22B3089B

是否有办法做到这一点，以便每个用户都有不同的主键/id?

IS there anyway to make it so that each user has a different primary key/id?

推荐答案

领域是一个对象数据库，因此您每次都需要创建一个新对象:

Realm is an object database, so you need to create a new object every time:

try! realm.write {

    user = User() // Create a new user instance

    user.userName = userNameTextField.text!
    user.passWord = passWordTextField.text!
    user.email = emailTextField.text!
    user.name = fullNameTextField.text!
    user.age = ageTextField.text!
    user.id = UUID().uuidString

    realm.add(user)

}
