@cloneField

Use the @cloneField directive to clone the value of another field.

The @cloneField directive can only be used in conjunction with the @readonly directive.

Example

With the following schema definition, the username field will be read-only and will clone the value of the email field:

user.graphql

type User @crudType {
    email: String!
    username: String! @cloneField(from: "email") @readonly
}
