MVC外键绑定

我试图先使用代码设置一个项目,但外键有问题。我有一个非常简单的带有导航属性的类。我试图设置外键列名,但不起作用,而是创建了另一列。

public class Point
{
    public int PointId { get; set; }

    public int AccountId { get; set; }

    [ForeignKey("AccountId")]
    public virtual Account Account { get; set; }

    public Decimal Balance { get; set; }
    public DateTime Date { get; set; }
    public int CategoryId { get; set; }

    [Required]
    public virtual Category Category { get; set; }
}

在迁移文件中,我有:

CreateTable(
            "dbo.Points",
            c => new
                {
                    PointId = c.Int(nullable: false, identity: true),
                    AccountId = c.Int(nullable: false),
                    Balance = c.Decimal(nullable: false, precision: 18, scale: 2),
                    Date = c.DateTime(nullable: false),
                    CategoryId = c.Int(nullable: false),
                    Account_AccountId = c.Int(),
                })
            .PrimaryKey(t => t.PointId)
            .ForeignKey("dbo.Accounts", t => t.AccountId, cascadeDelete: true)
            .ForeignKey("dbo.Categories", t => t.CategoryId, cascadeDelete: true)
            .ForeignKey("dbo.Accounts", t => t.Account_AccountId)
            .Index(t => t.AccountId)
            .Index(t => t.CategoryId)
            .Index(t => t.Account_AccountId);

正如你所看到的 Account_AccountId 列已创建,但我希望 AccountId 列用作外键。

[编辑]

我发现我在 OnModelCreating 职能部门负责:

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        base.OnModelCreating(modelBuilder);

        modelBuilder.Entity<Point>()
            .HasRequired(c => c.Account)
            .WithMany().HasForeignKey(e => e.AccountId)
            .WillCascadeOnDelete(false);

        modelBuilder.Entity<Category>()
            .HasRequired(s => s.Account)
            .WithMany().HasForeignKey(e => e.AccountId)
            .WillCascadeOnDelete(true);
    }

我也在那里指定了要用作外键的列,但不知何故,添加此项会导致创建一个新列。
