Hi Nexus,
The Update method call is totally unnecessary, indeed. Thanks for pointing
it out.
About your second comment, if I use Get the entity will be loaded
immediately while the Load method delays the loading until a property of the
root entity (User) is called (in this case, the OwnedBlogs collection).
I heard a few times that it is wise to wrap the list property just like
this:
public class User {
private IList<WebLog> ownedBlogs { get; set; }
public void AddBlog(WebLog webLog) {
this.ownedBlogs.Add(webLog);
}
public IEnumerable<WebLog> OwnedBlogs {
get { return this.ownedBlogs; }
}
}
I'm sure this is a good
thing<http://www.google.com.br/url?sa=t&source=web&cd=1&ved=0CBoQFjAA&url=http%3A%2F%2Fen.wikipedia.org%2Fwiki%2FLaw_of_Demeter&ei=KTXATPmAFoP-8AahsPDrBA&usg=AFQjCNGEB0daZpegnR5NWGCb312GaiySww&sig2=ECjwRdSjceR7cphikEclsA>,
but I wonder if this has something to do with the problem I mentioned
(necessity of loading the user entity to insert a related WebLog). I know
that in 99% of the situations there is no point in trying to avoid that
extra SELECT but my motivation is to understand better how NHibernate works
internally.
Thanks for your attention!
