Amazon web services – AWS Amplify: How to make the ID the same value as the owner?

I want to create a User model and I want the User ID to always be equal to the Owner ID.
How to do this?

This is my schema.graphql file content:

type User @model {
  id: ID! @default(value: @owner) # == owner
  name: String!
  description: String
  birthday: AWSDateTime
}

Thank you

    I had the same problem and found the solution highlighted below:

    type User
  @model
  @auth(rules: [
    { allow: owner, ownerField: "id" }
    { allow: private, operations: [read] }
  ])
{
  id: String @auth(rules: [
    { allow: owner, operations: [create, read, delete] } 
    { allow: private, operations: [read] }
  ])
  name: String!
  description: String
  birthday: AWSDateTime
}

    I’ve specified on the model level @auth rules to use the id field as the "ownerField" and give other authenticated users a read access.

    Then on the field level, I’ve removed the update access to the owner (again using @auth rules), so it is impossible to re-assign the record later on.

    for my case, I just added sub from Congnito User:

    type User
  @model
  @auth(rules: [{ allow: private, operations: [read] }, { allow: owner }]) 
  {
  id: ID!
  sub: String! @index(name: "bySub", queryField: "userBySub")
}

    sub is retrieved from cognito thanks to Auth.currentAuthenticatedUser(), when you login for the first time a new user row is added to the dynamo table User.
