Adding a method to a domain class

I have a domain class containing a couple of fields. I can access them from my .gsps. I want to add a method to the domain class, which I can call from the .gsps (this method is a kind of virtual field; it's data is not coming directly from the database).

How do I add the method and how can I then call it from the .gsps?

From stackoverflow qollin

• To add a method, just write it out like you would any other regular method. It will be available on the object when you display it in your GSP.

  def someMethod() {
  return "Hello."
  }
  

  Then in your GSP.

  ${myObject.someMethod()}
  

  From Hates_

• If you want your method to appear to be more like a property, then make your method a getter method. A method called getFullName(), can be accessed like a property as ${person.fullName}. Note the lack of parentheses.
