This is my domain class:

package tech.andean

class UrbanAuth {
    String id
    String huGroup
    String name
    String code

static belongsTo = [type:UrbanAuthType,ubigeus:Ubigeus]
    static hasMany = [roads:Road]

static constraints = {
        huGroup nullable:true,blank:true
    }

static mapping = {
        id generator:'assigned'
    }
}
