grails hasOne vs direct member variable

Question

Let\'s say I have a grails domain class that looks like

class Person {
    Address address
}

I could also declare it as

class P         


        

Answer 1

I suggest the following...

class Person {
  ...
  static hasOne = [address: Address]
}

class Address {
    ...
    static belongsTo = [person: Person]
}

A person has one address and the address belongs to one person.

By this way, when you delete a person, the address will be deleted too, without problems.

I think this is the better way to do this.
