ASP.NET MVC5。错误代码不允许在浏览器中查看控制器

Question

无法让我的事件控制器在浏览器中显示。我收到错误消息，指出我的列名无效

SqlException：列名“城市”无效。 列名“状态”无效。

事件模型代码 公开课活动 { [钥匙] 公共 int EventsId { 获取；放; }

    [Required(ErrorMessage = "Title is requied")]
    [StringLength(50, ErrorMessage = "Title cannot be more than 50 characters")]
    public string EventTitle { get; set; }

    [StringLength(150, ErrorMessage = "Description should not exceed 150 characters")]
    public string EventDescription { get; set; }

    [Required]
    public DateTime EventStartTime { get; set; }

    [Required(ErrorMessage = "Start Date cannot be in the past")]
    [DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0;MMdd/yyyy}")]
    public DateTime EventStartDate { get; set; }
    [Required]
    public DateTime EventEndTime { get; set; }

    [Required(ErrorMessage = "End date cannot be less than Start date")]
    [DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0;MMdd/yyyy}")]
    public DateTime EventEndDate { get; set; }

    public int AvaliableTickets { get; set; }

缺少很多信息。我的猜测是您数据库中的 Events 表不包含 City 或 State 列。
