一個屬性有很多照片。一張照片屬於一個物業。在nhibernate會議內收集藏品
在我的mvc控制器裏,我得到了整數參數數組。這些整數表示我想要刪除的照片的ID。
我正在使用nhibernate會話和事務來與db進行交互。
public ActionResult DeleteImgs(int[] data)
{
Property p = null;
using (ISession session = ....)
{
using(ITransaction transaction session.BeginTransaction())
{
Photo photo = session.Get<Photo>(data[0]);
p = session.Get<Property>(photo.Id);
// found images and delete them
foreach(int id in data)
{
Photo ph = session.Get<Photo>(id);
//remove property from association so I can delete photo
ph.Property = null;
session.Delete(ph);
session.SaveOrUpdate(ph);
}
//load property now with collection of remaining photos
// here IS THE PROBLEM, Even there is photos inside collection
// in debug I'm getting empty collection
p = session.Query<Property>().
.Fetch(x=>x.Photos).ToList() //empty?
.FirstOrDefault;
transaction.Commit();
}
}
return View();
}
