Hi!
I have a need to store several collections of the same "EntityType".
For instance, I have a class
public class HourlyRate
{
public virtual int Id { get; set; }
public virtual DateTime ValidFrom { get; set; }
public virtual DateTime ValidTo { get; set; }
public virtual decimal Amount { get; set; }
}
Then, on several entities, I would have
public class Employee {
public ISet<HourlyRate> RegularRates { get; set; }
public ISet<HourlyRate> NighltyRates { get; set; }
// etc.
}
I noticed that RegularRates and NighltyRates get mixed up in the
database -- they don't get stored as one would expect.
How to model this in OO terms so that NHibernate picks it up as
smoothly as possible?
I tried subclassing HourlyRate and that creates a table for each
"Rate", but I'd rather see that there would be a discriminator column
on the table holding HourlyRates. I tried changing the strategy to
table-per-subclass-hierarchy, but then I get WrongClassException when
loading entities.
Thanks,
Miha
