Here are the mappings. i am using mix of Auto mapping and override
mapping. i have included the mapping classes and the model classes.
once i put the AttributeTemplate to be abstract i cannot query it.
This is the query i am using. BTW if i remove the abstract from the
AttributeTemplate then its all working fine.
public IList<AttributeTemplate> AttributeTemplates
{
get
{
var cr = _session.CreateCriteria(typeof
(AttributeTemplate));
return cr.List<AttributeTemplate>();
}
}
------------------------------------------------Those are the mappings
------------------
public class EntityMap : IAutoMappingOverride<Entity>
{
public void Override(AutoMapping<Entity> mapping)
{
mapping.Table("tbl_Entity");
mapping.Id(x => x.Id)
.UnsavedValue(0)
.GeneratedBy.Identity();
mapping.Map(x => x.CreatedDate);
mapping.Map(x => x.UpdatedDate);
}
}
public class EntityTemplateMap : IAutoMappingOverride<EntityTemplate>
{
public void Override(AutoMapping<EntityTemplate> mapping)
{
mapping.Table("tbl_EntityTemplate");
}
}
public class AttributeTemplateMap :
IAutoMappingOverride<AttributeTemplate>
{
public void Override(AutoMapping<AttributeTemplate> mapping)
{
mapping.Table("tbl_AttributeTemplate");
}
}
public class ATImageMap : IAutoMappingOverride<ATImage>
{
public void Override(AutoMapping<ATImage> mapping)
{
mapping.Table("tbl_ATImage");
}
}
-------------------------------- And here are the model
classes-----------------------------
public abstract class Entity
{
protected Entity()
{
CreatedDate = UpdatedDate = DateTime.Now;
}
[Key]
public virtual int Id { get; set; }
public virtual DateTime CreatedDate { get; set; }
public virtual DateTime UpdatedDate { get; set; }
}
public abstract class EntityTemplate :Entity
{
}
public abstract class AttributeTemplate : EntityTemplate
{
public virtual string Title { get; set; }
public virtual string CodeName { get; set; }
public virtual bool Descriptor { get; set; }
}
public class ATImage : AttributeTemplate
{
}
public class ATLocation : AttributeTemplate
{
}
