使用NHibernate StatelessSession级联集合

Question

What is the proper way to bulk insert entities which contain collections of other entities (a HasMany mapping), using stateless sessions?

Eg Parent class is mapped like this:

class ParentMap : ClassMap<Parent>
{
    public ParentMap()
    {
        Id(x => x.Id)
           .GeneratedBy.Increment();

        HasMany(x => x.ChildNodes)
           .KeyColumns.Add("Parent_id")
           .Cascade.All();
    }  
}

Stateless session ignores the Cascade option, so child nodes are not persisted automatically. I could iterate through the collection myself, but then I cannot set the relation, because Parent_id column does not exist as a property I could write to.

Am I missing something?

您必须在子类中创建Parent属性，或者使用有状态会话。
