问题
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"
}
}
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()
}
The issue is that the created user objects have the same "id"/Primary key:
Jane Vergo is 17 years old ID: A6A67E2D-C9A9-4D6B-815C-27BC22B3089B
Jake Lawson is 19 years old ID: A6A67E2D-C9A9-4D6B-815C-27BC22B3089B
Luke Cage is 20 years old ID: A6A67E2D-C9A9-4D6B-815C-27BC22B3089B
IS there anyway to make it so that each user has a different primary key/id?
回答1:
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)
}
