Question

I look through the internet and I didnt find yet an answer for my question. Should be pretty easy:

class Parent {
  String name
  Child child
}

When I have a child object, how can I get the Parent by it?
like:

def Parent = Parent.findByChild(child)

How am I able to get a Parent object by it child?

thanks

Where have you looked?

Are these domain classes? If so, then you can connect them via has_many and belongs_to:

class Parent {
    String name
    List children
    static has_many = [ children: Child ]
}

class Child {
   static belongs_to = [ parent: Parent ]
}

Then you can just write child.parent
