Hi, I'm new to NHibernate and have some general Questions about
mapping of class hierarchies. I'm using mapping attributes.
I have a self-referencing base-class. I tried this:
[Class(NameType = typeof(BaseClass), Table = "BASE")]
public abstract class BaseClass
{
[Id(0, Name = "Id", Column = "ID")]
[Generator(1, Class = "hilo")]
public virtual long Id { get; set; }
[ManyToOne(Column = "PARENT_ID", ForeignKey = "FK_BASE_PARENT")]
public virtual BaseClass Parent { get; set; }
}
My intention was to inherit some classes of this BaseClass so that
they all are self-referencing without to reprogramm it in every
instance of my classes.
I Know that this doesn't work (NHibernate throws an exception) because
the type of the Parent-property is by design wrong (BaseClass is
abstract and can never be load).
So I tried this:
[Class(NameType = typeof(BaseClass), Table = "BASE")]
public abstract class BaseClass
{
[Id(0, Name = "Id", Column = "ID")]
[Generator(1, Class = "hilo")]
public virtual long Id { get; set; }
[Property(Column = "PARENT_ID")]
public virtual long ParentId { get; set; }
}
... with of course worked. But now I have no foreigh-key to myselfe.
Is there a way to generate a foreign-key?
Who can help me?
