Question

好的，所以我有一个名为“商业”的对象（我知道，我知道，“商业商业对象”）当它保存时，它的外键会以某种方式丢失。其他一切都在节省。我已经完成了代码并跟踪了对象直到

session.SaveOrUpdate（BusinessObject的）;

方法。那一点上的物体是完整的，外国物业似乎就在那里。但是，在保存时，外部ID不在业务表中。我只能想象这可能是因为我没有正确映射它们？

这是他们被映射的地方：

<many-to-one insert="false" update="false" name="_Township" column="TownshipId" class="HQData.Objects.Township, HQData" />

    <many-to-one insert="false" update="false" name="_User" column="UserId" class="HQData.Objects.User, HQData" />

    <many-to-one insert="false" update="false" name ="_SubCategory" column="SubCategoryId" class="HQData.Objects.SubCategory, HQData"/>

以下是加载和保存对象的位置：

HQData.Objects.Business business = null;
            if (BusinessId != 0)
                business = BusinessManager.GetBusiness(BusinessId);
            else
                business = new HQData.Objects.Business();
            business._SubCategory = CategoryManager.GetCategory(Convert.ToInt32(ddlCategory.SelectedValue.Trim()));
            business.Name = ControlHelper.Sanitize(txtName.Text.Trim());
            business.Address1 = ControlHelper.Sanitize(txtAddress.Text.Trim());
            business._Township = TownshipManager.GetTownshipByCityorZip(ControlHelper.Sanitize(txtTownship.Text));
            business.PhoneNumber = ControlHelper.Sanitize(txtPhone.Text.Trim());
            business.FaxNumber = ControlHelper.Sanitize(txtFax.Text.Trim());
            business.Email = ControlHelper.Sanitize(txtEmail.Text.Trim());
            business.Website = ControlHelper.Sanitize(txtWebsite.Text.Trim());
            business.AboutUs = ControlHelper.Sanitize(txtAboutUs.Text.Trim());
            business._User = UserManager.GetCurrentUser();


            BusinessManager.SaveBusiness(business);

感谢您的帮助。

Answer 1

将插入更新属性设置为true或将其删除。

Answer 2

你的意思是business._SubCategory.SubCategoryId

并且不确定GetCurrentUser会返回什么，但是如果Id也是......

business._User.UserId？

NHibernate映射问题（我认为）
