Question

This is my entity class and login code. My last login remains null in db with no exception thrown. i tried logging the hibernate sql statements. It seem that the update statement isn’t executed…

entity:

class Users {
  static hasMany = [farm:Farms,report:Reports,reportMessage:ReportMessages,notifications:Notifications]

  String userName 
  String Password
  Date lastLogin
  String userImage

  static constraints = {
    userName (blank:false, unique:true)
    Password (blank:false)
    userImage (blank:false)
    lastLogin (nullable:true, blank:true)
  }
}

login code

def login(user)
{
    def status = false;        
    Users u = user;
    Users users = Users.findByUserName(u.userName)
    PasswordCodec pwd = new PasswordCodec();
    u.Password = pwd.encode(u.Password)
    if (users !=null && u.Password.equals(users.Password))
    {
        u.lastLogin = new Date()
        u.save()
        status = true
    }
}

Answer 1

It looks like you are assigning the lastLogin date to the command object passed with the request. The stored domain object seems not to be updated:

u.lastLogin = new Date()
u.save()

should be replaced by

users.lastLogin = new Date()
users.save()

Hope that helps.
