Why are my Fluent NHibernate SubClass Mappings generating redundant columns?
- by Brook
I'm using Fluent NHibernate 1.x build 694, built against NH 3.0
I have the following entities
public abstract class Card
{
public virtual int Id { get; set; }
public virtual string Name { get; set; }
public virtual string Description { get; set; }
public virtual Product Product { get; set; }
public virtual Sprint Sprint { get; set; }
}
public class Story:Card
{
public virtual double Points { get; set; }
public virtual int Priority { get; set; }
public virtual IList<Task> Tasks { get; set; }
}
And the following mappings
public class CardMap:ClassMap<Card>
{
public CardMap()
{
Id(c => c.Id)
.Index("Card_Id");
Map(c => c.Name)
.Length(50)
.Not.Nullable();
Map(c => c.Description)
.Length(1024)
.Not.Nullable();
References(c=>c.Product)
.Not.Nullable();
References(c=>c.Sprint)
.Nullable();
}
}
public class StoryMap : SubclassMap<Story>
{
public StoryMap()
{
Map(s => s.Points);
Map(s => s.Priority);
HasMany(s => s.Tasks);
}
}
When I generate my Schema, the tables are created as follows
Card
---------
Id
Name
Description
Product_id
Sprint_id
Story
------------
Card_id
Points
Priority
Product_id
Sprint_id
What I would have expected would have been to see the columns Product_id and Sprint_id ONLY in the Card table, not the Story table.
What am I doing wrong or misunderstanding?
