Hi folks,
I'm into a record versioning requirement of all mapped entities (using
hbm.xml files).
public class User
{
public virtual String UserName { get; set; }
public virtual String Password { get; set; }
(...)
public virtual Int32 SysVersion { get; set; }
}
I'm invoking IPostInsertEventListener from nhibernate.cfg.xml:
<event type="post-insert">
<listener class="myEvents.PostInsert, myAssembly />
</event>
This is the code:
public class PostInsert : IPostInsertEventListener
{
//IPreInsertEventListener
//public bool OnPreInsert(PreInsertEvent preInsertEvent)
//{
// Correction(preInsertEvent.Entity);
// return false;
//}
//internal static void Correction(object entity)
//{
// var sysVersion =
entity.GetType().GetProperties().FirstOrDefault
// (
// p => p.PropertyType == typeof(Int32) &&
p.Name.ToLower() == "sysversion"
// );
// if (sysVersion == null)
// return;
// sysVersion.SetValue(entity, 1, null);
//}
public void OnPostInsert(PostInsertEvent @event)
{
//@event.Entity
var sysVersion =
@event.Entity.GetType().GetProperties().FirstOrDefault
(
p => p.PropertyType == typeof(Int32) &&
p.Name.ToLower() == "sysversion"
);
if (sysVersion == null)
return;
sysVersion.SetValue(@event.Entity, 1, null);
}
I need centralize sysVersion Insert and Update and then audit both
operations in an audit table. Code runs sysVersion.SetValue, but, NH does
not save sysVersion=1 into the table.
Please can you help me ?
