不能在 ASP.NET 核心中使用我的 MySql 數據庫和身份

Question

我用 MVC 創建了一個 ASP.NET 核心 Web。 我用 Identity 搭建了它並添加了我的默認布局頁面並使用了登錄頁面。 現在我遇到了當我登錄時找不到我相信的“用戶名”和“密碼”列的問題。 我不太確定，我會感謝我能得到的所有幫助:)。 這是我的網站提出的錯誤：

MySqlException: Unknown column 'u.AccessFailedCount' in 'field list'

錯誤頁面中的紅色部分是：

var result = await _userManager.CreateAsync(user, Input.Password);

預先感謝！

更新：

這是一些代碼，由於某種原因，我得到了很多未包含在我的 ApplicationUser 中的“隨機”值。

我的應用程序用戶：

public class ApplicationUser : IdentityUser
    {
        public string Username { get; set; }
        public string Password { get; set; }
    }

我的 AuthDbContext：

public class AuthDbContext : IdentityDbContext<ApplicationUser>
    {
        public AuthDbContext(DbContextOptions<AuthDbContext> options)
            : base(options)
        {
        }

        protected override void OnModelCreating(ModelBuilder builder)
        {
            base.OnModelCreating(builder);
            builder.Entity<ApplicationUser>(entity =>
            {
                entity.ToTable(name: "users");
            });
            
            // Customize the ASP.NET Identity model and override the defaults if needed.
            // For example, you can rename the ASP.NET Identity table names and more.
            // Add your customizations after calling base.OnModelCreating(builder);
        }
    }

獲取所有隨機值的遷移文件，我只想添加一個名為“users”的表，其 Id NOT NULL AUTO_INCREMENT PRIMARY KEY、用戶名 VARCHAR(40) 和密碼 VARCHAR(40)。 但是我得到了很多其他的專欄，我不知道它們來自哪里。

注意：我剛剛遷移，這一切似乎都還不錯。 但我只希望我的用戶能夠登錄，我想通過 MySql CLI 創建所有用戶后端。 但是我有所有那些我不知道該放入什么的磨損值。

Answer 1

如果您的實體包含屬性AccessFailedCount並且數據庫中確實缺少該列，則您可能忘記創建新的遷移。

有關更多信息，請參閱有關如何使用遷移的官方文檔。

或者您可能忘記配置 model 將列添加到OnModelCreating中的 OnModelCreating -Method。 請查看此鏈接以獲取有關如何配置數據庫模型的更多信息。

更新：那些額外的列是由身份服務器生成的，不應該被刪除。 只需將遷移應用到數據庫，一切都應該工作。
