display date / save date in Grails

Question

Is there any way to save / view date in our prefered format ? like dd/MM/yyyy instead of using simple date format everytime I save the date fields ?

for example: I would like to have

class User {
 Date birthDay ; 
}

the user will save the birthDay as '31/12/1988' for example and I would like to display it as that ... without format("dd/MM/yyyy") everytime I found the date (or converting string to date) for saving / updating)

Answer 1

You can use metaClass to display the date in wanted format.

Date.metaClass.toString = {
  -> format('dd/MM/yyyy')
}

If you're talking about date display, you'd better register an own PropertyEditor - with it, will use PropertyEditor's formatting.

If it's about saving to database, you'll need to set up a [custom Hibernate type mapping][2].
