EF 迁移：参数 @objname 不明确或声明的 @objtype (COLUMN) 错误

Question

我正在尝试通过迁移更新我的数据库。当我手动删除所有表然后手动重新创建时，我可能搞砸了。

我先使用代码，Add-Migration 命令给了我这个：

 public override void Up()
        {
        DropForeignKey("[dbo.Products]", "[Bundle_Id]", "[dbo.Bundles]");
        DropForeignKey("[dbo.Defects]", "[Product_Id]", "[dbo.Products]");
        DropForeignKey("[dbo.Defects]", "[User_Id]", "[dbo.Users]");
        RenameColumn(table: "[dbo.Products]", name: "[Bundle_Id]", newName: "[Bundles_BundlesId]");
        RenameColumn(table: "[dbo.Defects]", name: "[Product_Id]", newName: "[Products_ProductsId]");
        RenameColumn(table: "[dbo.Defects]", name: "[User_Id]", newName: "[Users_UsersId]");
        RenameIndex(table: "[dbo.Products]", name: "[IX_Bundle_Id]", newName: "[IX_Bundles_BundlesId]");
        RenameIndex(table: "[dbo.Defects]", name: "[IX_Product_Id]", newName: "[IX_Products_ProductsId]");
        RenameIndex(table: "[dbo.Defects]", name: "[IX_User_Id]", newName: "[IX_Users_UsersId]");
        DropPrimaryKey("[dbo.Bundles]");
        DropPrimaryKey("[dbo.Defects]");
        DropPrimaryKey("[dbo.Products]");
        DropPrimaryKey("[dbo.Users]");
        AddColumn("[dbo.Bundles]", "[BundlesId]", c => c.Long(nullable: false, identity: true));
        AddColumn("[dbo.Defects]", "[DefectsId]", c => c.Long(nullable: false, identity: true));
        AddColumn("[dbo.Defects]", "[ProductsId]", c => c.Int(nullable: false));
        AddColumn("[dbo.Defects]", "[UsersId]", c => c.Int(nullable: false));
        AddColumn("[dbo.Products]", "[ProductsId]", c => c.Long(nullable: false, identity: true));
        AddColumn("[dbo.Products]", "[BundlesId]", c => c.Int(nullable: false));
        AddColumn("[dbo.Users]", "[UsersId]", c => c.Long(nullable: false, identity: true));
        AddPrimaryKey("[dbo.Bundles]", "[BundlesId]");
        AddPrimaryKey("[dbo.Defects]", "[DefectsId]");
        AddPrimaryKey("[dbo.Products]", "[ProductsId]");
        AddPrimaryKey("[dbo.Users]", "[UsersId]");
        AddForeignKey("[dbo.Products]", "[Bundles_BundlesId]", "[dbo.Bundles]", "[BundlesId]");
        AddForeignKey("[dbo.Defects]", "[Products_ProductsId]", "[dbo.Products]", "[ProductsId]");
        AddForeignKey("[dbo.Defects]", "[Users_UsersId]", "[dbo.Users]", "[UsersId]");
        DropColumn("[dbo.Bundles]", "[Id]");
        DropColumn("[dbo.Defects]", "[Id]");
        DropColumn("[dbo.Defects]", "[ProductId]");
        DropColumn("[dbo.Defects]", "[UserId]");
        DropColumn("[dbo.Products]", "[Id]");
        DropColumn("[dbo.Products]", "[BundleId]");
        DropColumn("[dbo.Users]", "[Id]");
        }

    public override void Down()
        {
        AddColumn("[dbo.Users]", "[Id]", c => c.Long(nullable: false, identity: true));
        AddColumn("[dbo.Products]", "[BundleId]", c => c.Int(nullable: false));
        AddColumn("[dbo.Products]", "[Id]", c => c.Long(nullable: false, identity: true));
        AddColumn("[dbo.Defects]", "[UserId]", c => c.Int(nullable: false));
        AddColumn("[dbo.Defects]", "[ProductId]", c => c.Int(nullable: false));
        AddColumn("[dbo.Defects]", "[Id]", c => c.Long(nullable: false, identity: true));
        AddColumn("[dbo.Bundles]", "[Id]", c => c.Long(nullable: false, identity: true));
        DropForeignKey("[dbo.Defects]", "[Users_UsersId]", "[dbo.Users]");
        DropForeignKey("[dbo.Defects]", "[Products_ProductsId]", "[dbo.Products]");
        DropForeignKey("[dbo.Products]", "[Bundles_BundlesId]", "[dbo.Bundles]");
        DropPrimaryKey("[dbo.Users]");
        DropPrimaryKey("[dbo.Products]");
        DropPrimaryKey("[dbo.Defects]");
        DropPrimaryKey("[dbo.Bundles]");
        DropColumn("[dbo.Users]", "[UsersId]");
        DropColumn("[dbo.Products]", "[BundlesId]");
        DropColumn("[dbo.Products]", "[ProductsId]");
        DropColumn("[dbo.Defects]", "[UsersId]");
        DropColumn("[dbo.Defects]", "[ProductsId]");
        DropColumn("[dbo.Defects]", "[DefectsId]");
        DropColumn("[dbo.Bundles]", "[BundlesId]");
        AddPrimaryKey("[dbo.Users]", "[Id]");
        AddPrimaryKey("[dbo.Products]", "[Id]");
        AddPrimaryKey("[dbo.Defects]", "[Id]");
        AddPrimaryKey("[dbo.Bundles]", "[Id]");
        RenameIndex(table: "[dbo.Defects]", name: "[IX_Users_UsersId]", newName: "[IX_User_Id]");
        RenameIndex(table: "[dbo.Defects]", name: "[IX_Products_ProductsId]", newName: "[IX_Product_Id]");
        RenameIndex(table: "[dbo.Products]", name: "[IX_Bundles_BundlesId]", newName: "[IX_Bundle_Id]");
        RenameColumn(table: "[dbo.Defects]", name: "[Users]_UsersId]", newName: "[User_Id]");
        RenameColumn(table: "[dbo.Defects]", name: "[Products_ProductsId]", newName: "[Product_Id]");
        RenameColumn(table: "[dbo.Products]", name: "[Bundles_BundlesId]", newName: "[Bundle_Id]");
        AddForeignKey("[dbo.Defects]", "[User_Id]", "[dbo.Users]", "[Id]");
        AddForeignKey("[dbo.Defects]", "[Product_Id]", "[dbo.Products]", "[Id]");
        AddForeignKey("[dbo.Products]", "[Bundle_Id]", "[dbo.Bundles]", "[Id]");
        }

我用方括号（“[”和“]”）将每个名字括起来，这显然对我的一些人有所帮助。我发帖是因为，你猜对了，它不适合我。

我总是得到 :

Either the parameter @objname is ambiguous or the claimed @objtype (COLUMN) is wrong.

有人能猜出是什么阻止我更新我的数据库吗？我应该从另一个项目重新开始吗？

谢谢！

编辑：在我的括号被错误放置的评论之后，我更新为：

    }
}

不幸的是，这并没有解决我的问题。

我的问题是，出于某种原因，当我运行 Create-Migration 时，它生成了一个引用 table 中不存在的字段的命令。一旦我解决了这个问题，它运行就完美了。
