Hello again.
One quick thing, it seems at the moment, the property that timestamps must
be called version or timestamp, otherwise you'll have to manually map it.
I tried using Timestamp but then NH tries to use datetime. That's why I'm
using a custom user type and it seems like it's working (at least the
PersistenceSpecification isn't throwing any errors.
So, what I need is to add this from my manual mapping class:
Version(d => d.Versao)
.TheColumnNameIs("Versao")
.SetAttributes(
new Attributes
{
{"type",
"ModeloOO.NH.UserTypeTimestamp,ModeloOO.NH"},
{"unsaved-value", "null"},
{"generated", "always"}
}
);
So that it is applied to all the types that derive from EntidadeBase class.
I tried this:
var modeloPersistencia =
AutoPersistenceModel.MapEntitiesFromAssemblyOf<Disciplina>()
.Where(
type => type == typeof (Disciplina)
) //comecar com disciplina
.WithConvention(convention =>
{
convention.DefaultLazyLoad = false;
convention.FindIdentity = field =>
field.Name == "Id";
convention.GetTableName = type =>
String.Concat(type.Name, "s");
convention.GetVersionColumnName =
type => "Versao";
convention.GetPrimaryKeyNameFromType
= type => String.Concat("Id", type.Name);
convention.IsBaseType = type => type
== typeof (EntidadeBase);
});
modeloPersistencia.ForTypesThatDeriveFrom<EntidadeBase>(
eb =>
eb.Version(d => d.Versao)
.TheColumnNameIs("Versao")
.SetAttributes(
new Attributes
{
{"type",
"ModeloOO.NH.UserTypeTimestamp,ModeloOO.NH"},
{"unsaved-value", "null"},
{"generated", "always"}
}
));
But by doing this it insists on generating a class definition for
Entidadebase....
Thanks.
Luis
