Question

使用breeze.webapi.nh（1.4.7）我在CredticardPayment对象上有一个简单的TPT / TPH（试过两个）（BasePayment，CreditcardPayment）查询工作得很好，我从基础和派生类中获取数据。

当尝试保存实体并且基类包含FK时，我收到此错误:(如果将FK移动到派生类，则保存起作用并且一切正常）

The given key was not present in the dictionary.
   at System.Collections.Generic.Dictionary`2.get_Item(TKey key)
   at Breeze.WebApi.NH.NHRelationshipFixer.GetRelatedEntity(String propName, IType propType, EntityInfo entityInfo, IClassMetadata meta, Boolean canUseSession)

   at YTourWeb.Controllers.BreezeApiController.SaveChanges(JObject saveBundle) in c:\Yayasoft\YTour\YTour\YTourWeb\Controllers\BreezeApiController.cs:line 46

有什么想法吗？

保存包：

{

    {

      "TotalAmount": 20,
      "CurrencyId": 1,
      "CurrencyRate": 3.5,

          "autoGeneratedKeyType": "Identity"
        }
      }
    }
  ],
  "saveOptions": {}
}
