Hi
I want to run some additional code AFTER a successful save (insert) to a
couple of entities after a successful commit. I use a session per request
strategy which is wrapped up as UOW.
I have Googled around a bit and have come up with the following idea.
1. OnSave add the saved entities to a temporary list
2. PostFlush enumerate through the saved list and run the extra code.
My question is, is this a sound premise? Are there any gotcha's that won't
run the code in some circumstances? If so is there a workaround.
I am also wanting to perform the same using onDelete and FindDirty for
updates.
public class AppInterceptor : EmptyInterceptor
{
private readonly IList<object> insertItems = new List<object>();
public override bool OnSave(object entity, object id, object[]
state, string[] propertyNames, IType[] types)
{
var campaign = entity as Campaign;
if (campaign != null)
insertItems.Add(campaign);
var contact = entity as Contact;
if (contact != null)
insertItems.Add(contact);
return base.OnSave(entity, id, state, propertyNames, types);
}
public override void PostFlush(ICollection entities)
{
base.PostFlush(entities);
foreach (var entity in insertItems)
{
var campaign = entity as Campaign;
if (campaign != null)
new LuceneCampaign().Index(campaign);
var contact = entity as Contact;
if (contact != null)
new LuceneContact().Index(contact);
}
}
}
I am steering away from the repository pattern so Session.Save could be
called anywhere in my code.
Many Thanks
Rippo
