C# NHibernate映射问题（我认为）

好的，我有一个名为“Business”的对象（我知道，我知道，“Business object”） 当它保存它的外键时，不知怎的丢失了。其他一切都在节省。我已经完成了代码并跟踪对象直到

session.SaveOrUpdate（businessObject）

方法。此时的对象是完整的，并且外来属性似乎在那里。但是，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地映射它们

以下是它们的映射位置：

<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"/>

谢谢你的帮助

你是认真的。_SubCategory.SubCategory id

不确定GetCurrentUser返回什么，但如果Id也是

---

business.\u User.UserId？

将插入更新属性设置为true或删除它们。

对象在business.cs文件中映射为：public virtual User{get；Set；}因此，我认为我无法设置ID值，我设置了整个对象，否？是，看起来您正在为子类别而不是子类别对象设置int。不要设置Id值，而是将子类别设置为object.Crap nevermind，只是看到了CategoryManager.GetCategory中的int内容。哎呀。

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);
