How to add constraints on inherited properties in a grails domain sub-class

Question

Here\'s what I\'d like to do:

class A {
  String string
  static constraints = {
    string(maxSize:100)
  }
}

class B extends A {
  static constraints = {
         


        

Answer 1

The way it was in 2.x:

As constraints is a closure executed by some ConstraintsBuilder, I'd try calling it from B, like

class B extends A { 
  static constraints = { 
    url(unique: true)
    A.constraints.delegate = delegate  # thanks Artefacto
    A.constraints()
  } 
}
