Grails Spring Security Plugin - Linking ONE-TO-ONE to a user's domain

Question

I am using Spring's security module to manage membership and authentication in my Grails application.

I am trying to associate a user domain class with a profile domain through a one-to-one association.

I added this line to User.groovy:

static hasOne = [userProfile:UserProfile]
static constraints = {
//...
             userProfile unique:true
}

and UserProfile.groovy:

User user

Alas, I had an error when calling UseRole.create (user, role).

There are several examples of how to get the same functionality that I am looking for. In particular, I want to associate any user with one profile object in order to expand it.

I also want to add a one-to-many relationship with messages and another table ...

Thanks best regards

PS: I get this error:
