Nhibernate 级联="；“全部”；不保存子实体

我认为下面的对象模型表示一个Party和PartyName具有多对一关系。我认为cascade=all I the Party.hbm应该让NHib保存孩子的Party名称

<many-to-one access="field.camelcase-underscore" class="Parties.Domain.Party" foreign-key="Party_FK" name="Party">
  <column name="PartyId" index="PartyIndex" not-null="true"/>
</many-to-one>
<property name="TheRequiredName" not-null="true" length="50"/>
<property name="EverythingElse" />
<property name="ContextUsed" length="50"/>
<property name="Salutation" length="20"/>
<property name="EffectivePeriod" type="Smack.Core.Data.NHibernate.UserTypes.DateRangeUserType, Smack.Core.Data">
  <column name="EffectiveStart"/>
  <column name="EffectiveEnd"/>
</property>

但它显然不是

<many-to-one access="field.camelcase-underscore" class="Parties.Domain.Party" foreign-key="Party_FK" name="Party">
  <column name="PartyId" index="PartyIndex" not-null="true"/>
</many-to-one>
<property name="TheRequiredName" not-null="true" length="50"/>
<property name="EverythingElse" />
<property name="ContextUsed" length="50"/>
<property name="Salutation" length="20"/>
<property name="EffectivePeriod" type="Smack.Core.Data.NHibernate.UserTypes.DateRangeUserType, Smack.Core.Data">
  <column name="EffectiveStart"/>
  <column name="EffectiveEnd"/>
</property>

有人能解释为什么PartyName不能与Party一起保存，以及如何修复吗

<many-to-one access="field.camelcase-underscore" class="Parties.Domain.Party" foreign-key="Party_FK" name="Party">
  <column name="PartyId" index="PartyIndex" not-null="true"/>
</many-to-one>
<property name="TheRequiredName" not-null="true" length="50"/>
<property name="EverythingElse" />
<property name="ContextUsed" length="50"/>
<property name="Salutation" length="20"/>
<property name="EffectivePeriod" type="Smack.Core.Data.NHibernate.UserTypes.DateRangeUserType, Smack.Core.Data">
  <column name="EffectiveStart"/>
  <column name="EffectiveEnd"/>
</property>

未通过测试（和输出）

[测试]
public void可以保存并加载所有属性（）
{
var partyName=nameeds.DevName；
partyName.Party=\u Party；
Assert.That（_party.Names.First（），Is.EqualTo（partyName））；
使用（var tx=\u session.BeginTransaction（））
{
_会话。保存（_方）；
tx.Commit（）；
}
_session.Clear（）；
党创建党；
使用（var tx=\u session.BeginTransaction（））
{
foundParty=\u session.Get（\u party.Id）；***通过名称映射
inverse=true
，您必须显式调用session.Save（partyNameObject）在集合的每个成员上。如果您希望NHibernate在保存PartyObject时自动保存集合的成员，则需要将名称
反向属性更改为
反向=false
。这会告诉NHibernate您希望Party控制Party和PartyName之间的关系。您必须：o记住将每个partyNameObject添加到Party.Names集合中。否则，在调用
Session.Save（partyObject）时，它们将不会被保存
。请记住，让父对象控制关系可能很方便，但如果您碰巧在未加载PartyNames集合的情况下保存PartyObject，则NHibernate会将其Party FK更新为Null。在这种情况下，如果在名称上设置了某些级联选项，您可能会发现NHibernate也会删除它们。
有道理，它不起作用（派对仍然不能拯救PartyName）在我的第一次回复中遗漏了一些细节，并更新了我的答案。我对此仍有疑问，我们一起努力解决所有问题。看一看-干杯
