MVC 无效的对象名称“dbo.Staffs”错误

Question

我收到了错误Invalid object name 'dbo.Staffs'.，但我不知道为什么。实际上，我使用 EF 删除并重新创建了我的数据库，因为之前我遇到了其他错误。但我很确定我正确地重新创建了它，因为我已经为其他程序以相同的方式完成了它并且它工作正常。

.edmx 数据库图

控制器

    private StaffPortalDBEntities1 db = new StaffPortalDBEntities1();
    SqlConnection cnn = new SqlConnection(ConfigurationManager.ConnectionStrings["StaffPortalDBConnectionString"].ConnectionString);

    [Authorize]
    public ActionResult Index()
    {
        var userEmail = User.Identity.Name;
        var model = db.Staffs.Where(i => i.Email == userEmail).Include("Histories").Include("CurrentApplications").FirstOrDefault();

        return View(model);
    }

我得到的错误是var model = db.Staffs.Where(i => i.Email == userEmail).Include("Histories").Include("CurrentApplications").FirstOrDefault();这一行

生成的 Staff 类

public partial class Staff
{
    public Staff()
    {
        this.Histories = new HashSet<History>();
        this.CurrentApplications = new HashSet<CurrentApplication>();
    }

    public int StaffID { get; set; }
    public string Name { get; set; }
    public string Email { get; set; }
    public Nullable<decimal> AllocatedLeave { get; set; }
    public Nullable<int> BalanceLeave { get; set; }

    public virtual ICollection<History> Histories { get; set; }
    public virtual ICollection<CurrentApplication> CurrentApplications { get; set; }
}

试试这个：

var model = db.Staffs.Where(i => i.Email == userEmail).Include(x=>x.Histories).Include(x=>x.CurrentApplications).FirstOrDefault();
