I have following problem using fluent nhibernate and HasMany. I've search through google and SO for similar problem but any of solutions I've found does not solve my problem.
I have following entites mapped (I omitted most properties for clarity):
PaymentSchedule.cs
public class PaymentSchedule
{
public virtual BinaryId Id { get; set; }
public virtual IList<PaymentToSchedule> Payments { get; set; }
}
PaymentToSchedule.cs
public class PaymentToSchedule
{
public virtual BinaryId Id { get; set; }
public virtual PaymentSchedule PaymentSchedule { get; set; }
}
Mapping files
PaymentScheduleMap.cs
public class PaymentScheduleMap : ClassMap<PaymentSchedule>
{
public PaymentScheduleMap()
{
Table("A_Payment_Schedule");
Id(x => x.Id, "A_Payment_Schedule_Id").CrmId();
HasMany<PaymentToSchedule>(x => x.Payments).Table("A_Payment_To_Schedule").KeyColumns.Add("A_Payment_Schedule_Id").Fetch.Select();
}
}
PaymentToScheduleMap.cs
public class PaymentToScheduleMap : ClassMap<PaymentToSchedule>
{
public PaymentToScheduleMap()
{
Table("A_Payment_To_Schedule");
Id(x => x.Id, "A_Payment_To_Schedule_Id").CrmId();
References(x => x.PaymentSchedule, "A_Payment_Schedule_Id");
}
}
Basically I want to fetch list of PaymentToSchedule entites when loading PaymentSchedule object. Now, to do this, I must use such queries:
var paymentSchedules = dataAccess.Session.QueryOver<PaymentSchedule>().List();
and for each of the payment schedule
var paymentToSchedule = (from pts in dataAccess.Session.Query<PaymentToSchedule>()
where pts.PaymentSchedule.Id == ps.Id).
ToList<PaymentToSchedule>();
This works fine, but is there a way to fetch list of PaymentToSchedule entites while querying PaymentSchedule?
var paymentSchedules = dataAccess.Session.QueryOver<PaymentSchedule>()
.Fetch(x => x.Payments).Eager;
.List();
// payments are already initialised, you can safly do
var allPayments = paymentSchedules.SelectMany(ps => ps.Payments).ToList();
