使用流畅的NHibernate AutoMapping保存级联

如何使用具有Fluent NHibernate的AutoMap持久性模型"打开"级联保存？

如:

我救人,手臂也应该保存.目前我明白了

"对象引用未保存的瞬态实例 - 在刷新之前保存瞬态实例"

public class Person : DomainEntity
{
  public virtual Arm LeftArm { get; set; }
}

public class Arm : DomainEntity
{
  public virtual int Size { get; set; }
}

我发现了一篇关于这个主题的文章,但似乎已经过时了.

这适用于新的配置位.有关更多信息,请参阅http://fluentnhibernate.wikia.com/wiki/Converting_to_new_style_conventions

//hanging off of AutoPersistenceModel    
.ConventionDiscovery.AddFromAssemblyOf()


public class CascadeAll : IHasOneConvention, IHasManyConvention, IReferenceConvention
{
    public bool Accept( IOneToOnePart target )
    {
        return true;
    }

    public void Apply( IOneToOnePart target )
    {
        target.Cascade.All();
    }

    public bool Accept( IOneToManyPart target )
    {
        return true;
    }

    public void Apply( IOneToManyPart target )
    {
        target.Cascade.All();
    }

    public bool Accept( IManyToOnePart target )
    {
        return true;
    }

    public void Apply( IManyToOnePart target )
    {
        target.Cascade.All();
    }
}

更新以与当前版本一起使用:

public class CascadeAll : IHasOneConvention, IHasManyConvention, IReferenceConvention
{
    public void Apply(IOneToOneInstance instance)
    {
        instance.Cascade.All();
    }

    public void Apply(IOneToManyCollectionInstance instance)
    {
        instance.Cascade.All();
    }

    public void Apply(IManyToOneInstance instance)
    {
        instance.Cascade.All();
    }
}
