Question

I have this setup

class User {
  Date lastLogin

  // logins is a history of logins
  static hasMany = [logins : Date]

  def setLastLogin(Date date) {
    if (date) {
      lastLogin = date
      addToLogins(date) 
    }
  }
}

GORM is generating a table MEMBER_LOGINS which currently looks like this:

USER_ID, LOGINS

Instead I would like

USER_ID, DATE

I tried adding a mapping in User

static mapping = {
  logins column: 'date';
}

But that just changed the foreign key so i now have

DATE, LOGINS

How can I change the LOGINS column?

Thanks!

You can to use hibernate hbm files to map your columns

Or you can do it

class User {
    static hasMany = [logins: Date]
    def setLastLogin ...
    static mapping = { 
        hasMany joinTable: 
            [name: 'logins', 
                key: 'person_id', 
                column: 'dates', 
                type: "date"] 
    } 
}
