How can I override the default error message in Grails?

I have a Person object with a lastName field. The lastName field cannot be blank. When the user submits a form blank value in the lastName field, the error message that the user sees is:

Property [lastName] of class [com.example.Person] cannot be blank

This error message is lame. I want to customize it to something more user friendly, like "The Last Name field cannot be blank"

How do I do that?

Solution

  • See Chapter 7 of the docs: http://grails.org/doc/latest/

    You would change grails-app/i18n/messages.properties and add

    person.lastName.blank=The Last Name field cannot be blank
