Telling GORM not to persist a property

Is there a way of telling GORM not to pers开发者_运维百科ist a property? I'm planning to define a confirm password property on my User class that I'll use for validation, but shouldn't be persisted.

Using transient key word GORM can be directed not to persist specific property.

Following code snippets shows the use of transient proerties

class Book {
  static transients = [ "digitalCopy" ]

  static constraints = {
    releaseDate(nullable: true)
  }    

  String author
  String title
  Date releaseDate
  File digitalCopy
}

digitalCopy property included in transient declaration notifies GORM not to persist digitalCopy

OK - just managed to answer my own question with some more searching. Should have been more patient. A static transients property "defines a list of property names that should not be persisted to the database. This is often useful if you have read-only getters that include logic."
