通过相关业务对象的属性加载单个业务对象

Question

我正在字符串中根据相关对象中的属性加载单个业务对象。在这种情况下，存在与材料和工厂具有单一关系的扩展材料。

此方法位于AppServer类上。当我用这段代码运行附加的测试时，我得到了正确的结果和通过的测试，但如果我取消注释行Broker.GetBusinessObject<ExtendedMaterial>("Plant.PlantCode LIKE " + plantCode);

然后我得到异常Habanero.Base.Exceptions.InvalidPropertyNameException : The given property name 'PlantCode' does not exist in the collection of properties for the class 'ExtendedMaterial'

我做错了什么？

    public ExtendedMaterial GetExtendedMaterial(string materialCode, string plantCode)
    {
      //  return Broker.GetBusinessObject<ExtendedMaterial>("Plant.PlantCode LIKE " + plantCode);
        return Broker.GetBusinessObjectCollection<ExtendedMaterial>("Plant.PlantCode LIKE " + plantCode).FirstOrDefault();
    }

    [Test]
    public void GetExtendedMaterial_WhenExists_ShouldReturnExtendedMaterial()
    {
        //---------------Set up test pack-------------------
        var material = CreateSavedMaterial();
        var plant = GetBOTestFactory<Plant>().CreateSavedBusinessObject();
        var extendedMaterial = CreateSavedExtendedMaterial(plant, material);
        IAppServer appServer = new AppServer(CreateDeviceManagerWithDevice());
        //---------------Assert Precondition----------------
        Assert.AreSame(plant, extendedMaterial.Plant);
        Assert.AreSame(material, extendedMaterial.Material);
        //---------------Execute Test ----------------------
        var actualExtendedMaterial = appServer.GetExtendedMaterial(material.Code, plant.PlantCode);
        //---------------Test Result -----------------------
        Assert.AreSame(extendedMaterial, actualExtendedMaterial);
    }

如果您的DataAccessor是DataAccessorDB，这确实有效，但我最近在一些单元测试中注意到，它对DataAccessorInMemory不起作用。尝试使用数据库进行测试，看看是否有效。如果没有，请在http://redmine.habanerowiki.com/
