我有2个相互引用的类。这是我们CRM需要的一种奇怪的情况。
我有一个Organization和EmAddress表和类。组织继承自Subscriber,它也有一个表。我认为这可能是我的问题,或者我不能在这些上设置Inverse,因为没有“HasMany”......
插入/更新的顺序是.. 插入电子邮件 INSERT组织 更新电子邮件以设置Email.Subscriber
Email.Subscriber需要“NOT NULL”,所以这不起作用。如何更改顺序,我不能使用Inverse,因为没有列表。只有2个参考。
public class Organization : Subscriber
{
public override string Class { get { return "Organization"; } }
EmAddress PrimaryEmailAddress {get;set;}
}
public class OrganizationMap : SubclassMap<Organization>
{
public OrganizationMap()
{
Table("Organization");
KeyColumn("Organization");
References(x => x.PrimaryEmail,"PrimaryEmailAddress").Cascade.SaveUpdate();
}
}
public EmAddressMap()
{
Id(x => x.Id, "EmAddress");
Map(x => x.EmailAddress, "eMailAddress");
References<Subscriber>(x => x.Subscriber,"Subscriber").LazyLoad().Fetch.Select().Not.Nullable();
/*not.nullable() throw s error. NHibernate INSERTS email, INSERTS org, UPDATES email. */
}
public class EmAddress
{
public virtual Guid Id { get; set; }
public virtual string EmailAddress { get; set; }
public virtual Subscriber Subscriber { get; set; }
}
//Implementation
var session = NHIbernateHelper.GetSession();
using(var tx = session.BeginTransaction())
{
var org = new Organization();
org.PrimaryEmail = new EmAddress(){Subscriber = org};
session.Save(org);
tx.commit();
}
答案 0 :(得分:0)

只有一方使用多对一(流利:“参考”),另一方使用一对一(流利:“HasOne”)。
