Any examples of mapping using TablePerHierarchy?
I'm having issues trying to get it up and running. Getting
NHibernate.MappingException: No persister for [SubClass] exceptions. I
must be doing something wrong:
var mapper = new ConventionModelMapper();
var baseEntityType = typeof(DomainEntity);
mapper.IsEntity((t, declared) =>
baseEntityType.IsAssignableFrom(t) && baseEntityType != t && !
t.IsInterface);
mapper.IsRootEntity((t, declared) =>
baseEntityType.Equals(t.BaseType));
mapper.Class<DomainEntity>(map => map.Id(x => x.Id, m =>
m.Generator(Generators.Identity)));
mapper.Class<Event>(e => e.Discriminator(map =>
{
map.Column("type");
map.Type(NHibernateUtil.String);
map.NotNullable(true);
}));
mapper.Subclass<Molt>(x =>
{
x.DiscriminatorValue("Molt");
});
mapper.Subclass<Feeding>(x =>
{
x.DiscriminatorValue("Feeding");
});
mapper.BeforeMapClass += (mi, t, map) => map.Table("myapp_" +
t.Name.MakePlural());
mapper.BeforeMapBag += (insp, prop, map) =>
map.Cascade(Cascade.All);
return mapper;
