C＃實體框架外鍵屬性被忽略

Question

我有「用戶」和「產品」實體，產品有外鍵給用戶（UserId - > User）。我想多一個外鍵添加到用戶的產品實體，但得到錯誤的遷移

我的更新產品實體（例如）

[ForeignKey("User")] 
    public int? UserId { get; set; } 
    [ForeignKey("AcceptedBy")] 
    public int? AcceptedById { get; set; }  
    [ForeignKey("AcceptedById")] 
    public User AcceptedBy { get; set; } 
    [ForeignKey("UserId")] 
    public User User { get; set; } 

Automaticaly創建遷移：

 DropForeignKey("dbo.Products", "UserId", "dbo.Users"); 
     AddColumn("dbo.Products", "AcceptedById", c => c.Int()); 
     AddColumn("dbo.Products", "User_Id", c => c.Int()); 
     CreateIndex("dbo.Products", "AcceptedById"); 
     CreateIndex("dbo.Products", "User_Id"); 
     AddForeignKey("dbo.Products", "AcceptedById", "dbo.Users", "Id"); 
     AddForeignKey("dbo.Products", "User_Id", "dbo.Users", "Id"); 
     DropColumn("dbo.Products", "AcceptedByUserId"); 

所以我UserId屬性被忽略

我認爲你有很多ForeignKey數據註釋。

public int? UserId { get; set; } 
[ForeignKey("UserId")] 
public User User { get; set; } 

public int? AcceptedById { get; set; }  
[ForeignKey("AcceptedById")] 
public User AcceptedBy { get; set; }
