Asp.net mvc 4 如何在ASP.NET MVC4中使用实体框架插入和更新两个表

我正在使用ASP.NET MVC4创建一个演示应用程序，其中包含以下两个表：

表TBL客户信息：

表TBL客户联系人：

注意：这些表具有一对多关系

我有查看详细信息、编辑和插入的视图，还有一个局部视图，用于帮助我插入第二个表数据tblCustomerContact此局部视图用于索引页

之后，创建一个MVC项目，然后添加一个名为NewCustomerInformation.edmx的ADO.Net实体数据模型，并映射存储过程

控制器代码

_CustomerInformation Entities.EntrytblCustomerQuery.CurrentValues.SetValuestblCustomerInfo； _customerinformationentities.SaveChanges； _CustomerInformation Entities.EntrytblCustomerInfo.State=EntityState.Modified； _customerinformationentities.SaveChanges； tblCustomerContact tblCust=新tblCustomerContact； } 返回视图； }

        public ActionResult getList()
        {
            return View(_custmerInformationEntities.tblCustomerInformations);
        }

        public ActionResult Edit(int id = 0)
        {
            tblCustomerInformation _tblCustomerInformation = _custmerInformationEntities.tblCustomerInformations.Find(id);
            tblCustomerContact tblCont = _custmerInformationEntities.tblCustomerContacts.Single(p => p.CustomerId == id);
            return View(_tblCustomerInformation);
        }
    }
}

索引

细节

编辑

部分视图\u客户联系人

我的问题是，当我尝试插入时，它可以正常工作，但当尝试更新我的表时，它不会更新。请帮助我，我是ASP.NET MVC新手

谢谢

若要更新数据库中的记录，必须在“编辑”视图中将CONSTRACTID作为隐藏键传递

CREATE TABLE [dbo].[tblCustomerContact]
(
    [CustomerId] [int] NOT NULL,
    [CustomerContactId] [int] NOT NULL,
    [CustomerAddress] [varchar](100) NULL,
    [CustomerContactNumber] [varchar](20) NULL,
    [CustomerPinCode] [varchar](10) NULL,

    CONSTRAINT [PK_tblCustomerContact] PRIMARY KEY CLUSTERED ([CustomerContactId] ASC)
)

ALTER TABLE [dbo].[tblCustomerContact] WITH CHECK 
ADD CONSTRAINT [FK_tblCustomerContact_tblCustomerInformation] 
FOREIGN KEY([CustomerId]) REFERENCES [dbo].[tblCustomerInformation] ([CustomerID])
