Hello all, after creating a sample web application POC using the
Entity Framework I am attempting to do the same with NH. I ran into
what is probably a very simple issue however I can't quite find the
solution. My web application is passing an Author object to my service
which then supposed to delete the author and all of its children
(Articles). I am not utilizing cascading delete so I am trying to nuke
those articles manually before I nuke the author, however I can't get
the author.Articles list to populate. In the below example
author.Articles is always null. I understand I must be missing
something regarding the disconnected nature of what I am attempting to
do here, but in Entity Framework I was able to simply attach my entity
to the ObjectContext (session in NH) and go from there as usual. I
recognize that I could simply query first for the Author instance
first, but the whole point is to avoid that query as I already have
that object being passed into the service. When I put a break-point
on the author I realize that there is no proxy class associated with
author.Articles, how do I get that proxy class to appear? Thank you.
public void DeleteAuthor(Author author)
{
using (ISession session = GetSession())
{
using (ITransaction tx = session.BeginTransaction())
{
try
{
foreach (Article article in author.Articles)
{
session.Delete(article);
}
session.Delete(author);
session.Flush();
tx.Commit();
}
catch (HibernateException)
{
tx.Rollback();
throw;
}
}
}
}
