Question

我有一个使用MVC5与身份和实体框架的项目。我首先使用数据库，并使用ASPNetUser.Id创建了许多表作为FK。所以，例如我有这张表：

CREATE TABLE [dbo].[Logs](
    [Id] [bigint] IDENTITY(1,1) NOT NULL,
    [LogTypeId] [smallint] NOT NULL,
    [Description] [varchar](5000) NOT NULL,
    [DateTime] [datetime] NOT NULL,
    [UserId] [nvarchar](128) NULL,
 CONSTRAINT [PK_Log] PRIMARY KEY CLUSTERED 
(
    [Id] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]

GO

SET ANSI_PADDING ON
GO

ALTER TABLE [dbo].[Logs] ADD  CONSTRAINT [DF_Log_DateTime]  DEFAULT (getdate()) FOR [DateTime]
GO

ALTER TABLE [dbo].[Logs]  WITH CHECK ADD  CONSTRAINT [FK_Log_AspNetUsers] FOREIGN KEY([UserId])
REFERENCES [dbo].[AspNetUsers] ([Id])
GO

ALTER TABLE [dbo].[Logs] CHECK CONSTRAINT [FK_Log_AspNetUsers]
GO

ALTER TABLE [dbo].[Logs]  WITH CHECK ADD  CONSTRAINT [FK_Log_LogType] FOREIGN KEY([LogTypeId])
REFERENCES [dbo].[LogTypes] ([Id])
GO

ALTER TABLE [dbo].[Logs] CHECK CONSTRAINT [FK_Log_LogType]
GO

所以，我创建了我的EntityFramework 6 edmx，我添加了所有表格，包括这一个。

之后，我使用Scaffolding作为CRUD，它很好地创建了Controller和Views。

但是...当我播放所有项目时，在索引视图中它会在行上抛出错误：

public ActionResult Index()
        {
            var logs = db.Logs.Include(l => l.LogType);
            return View(logs.ToList());  //----->>> HERE THROWS THE ERROR
        }

错误：

无效的列名称'AspNetUser_Id'。

查询尝试运行：

SELECT 
    1 AS [C1], 
    [Extent1].[Id] AS [Id], 
    [Extent1].[LogTypeId] AS [LogTypeId], 
    [Extent1].[Description] AS [Description], 
    [Extent1].[DateTime] AS [DateTime], 
    [Extent1].[UserId] AS [UserId], 
    [Extent2].[Id] AS [Id1], 
    [Extent2].[Description] AS [Description1], 
    [Extent1].[AspNetUser_Id] AS [AspNetUser_Id] //---> THIS FIELD DOES NOT EXISTS !!! 
    FROM  [dbo].[Logs] AS [Extent1]
    INNER JOIN [dbo].[LogTypes] AS [Extent2] ON [Extent1].[LogTypeId] = [Extent2].[Id]

那么，你知道为什么要寻找ASPNetUser_Id吗？该字段不存在。而且，为什么其他FK工作正常？

我试过没有成功：

再次创建emdx
从数据库更新edmx
更改FK的名称

任何想法???

感谢所有人！
