Question
I'm trying to get a web app working based on the S#arp Architecture. At the moment I have a the below code for my entity.
[Serializable]
public abstract class EventBase : Entity
{
#region Properties
[DomainSignature]
public virtual string Name { get; set; }
public virtual string Description { get; set; }
public virtual AgeRange Ages { get; set; }
public virtual int Rating { get; set; }
public virtual decimal Price { get; set; }
public virtual string PhoneNumber { get; set; }
public virtual string EmailAddress { get; set; }
public virtual string Website { get; set; }
public virtual EventState State { get; set; }
#endregion
protected EventBase() {}
protected EventBase(string name, string description)
{
// ReSharper disable DoNotCallOverridableMethodsInConstructor
Name = name;
Description = description;
Price = 0;
State = EventState.New;
// ReSharper restore DoNotCallOverridableMethodsInConstructor
}
}
This is mapped using Fluent NHibernate as follows
public class EventBaseMap : AutoMap<EventBase>
{
public EventBaseMap()
{
Id(x => x.ID).WithUnsavedValue(-1).GeneratedBy.Identity();
Component<AgeRange>(x => x.Ages, m =>
{
m.Map(x => x.From).TheColumnNameIs("AgeFrom");
m.Map(x => x.To).TheColumnNameIs("AgeTo");
});
JoinedSubClass<Music>("EventId", sub =>
{
sub.Map(x => x.Headliner);
});
}
}
I created a very simple repository using the very useful S#arp base repository classes.
public interface IEventRepository : INHibernateRepositoryWithTypedId<EventBase, int>
{
List<EventBase> FindByName(string searchPhase);
}
public class EventRepository : NHibernateRepository<EventBase>, IEventRepository
{
public List<EventBase> FindByName(string searchPhase)
{
return Session.Linq<EventBase>().Where(x => x.Name == searchPhase).ToList();
}
}
I can create entities in the db and return all records. When I try to test the FindByName method I get the below error.
NHibernate.QueryException: could not resolve property: Name of: Model.Events.EventBase
Does anyone have any ideas? Is it a problem with my mapping?
Thanks,
Solution
This is using the Auto-mapping feature. I thought you only explicitly map properties that you want to override or that don't meet the conventions?
If I add an explicit mapping this solves the issue but I am still not sure why.
