Question

I have a domain class:

class Person {
    String name
    Boolean likesGrails
    Boolean isSmart
}

and want to pre process the data (create a new property friend) before passing it to a view (which will use friend to decide stuff):

def people = Person.list()
people.each {
    it.friend = likesGrails && isSmart
}

How do i add this friend property? The code above doesn’t work (it complains that it.friend doesn’t exist).

Answer 1

You should just be able to add:

static transients = [ 'friend' ]
public boolean isFriend() {
  likesGrails && isSmart
}

To your domain class, then access person.friend in your view
