不能在 ASP.NET 核心中使用我的 MySql 数据库和身份

Question

I have created a ASP.NET Core Web with MVC. I scaffolded it with Identity and added my default layout page and used the login page. Now I have ran into the problem that when I log in it doesnt find the column "username" and "password" I belive. Im not quite sure and would appriciate all the help I can get:). This is the error that my website puts out:

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

and the red part in the error page is:

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

Thanks beforehand!

UPDATE:

Here is some code, I get a lot of "random" values that is not included in my ApplicationUser for some reason.

My ApplicationUser:

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

My 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);
        }
    }

The migrationfile that gets all the random values, I only want to add a table named "users" with Id NOT NULL AUTO_INCREMENT PRIMARY KEY, Username VARCHAR(40) and Password VARCHAR(40). But I get soo many other columns that I dont know where they are comming from.

NOTE: I just migrated and it all seems to kinda work. But I only want my users to be able to login, I want to create all users backend via MySql CLI. But I have all those weard values that I dont know what to put in..

Answer 1

If your entity contains the property AccessFailedCount and the column is indeed missing in the database, you might have forgotten to create a new migration.

See the official documentation on how work with migrations for more information.

Or maybe you forgot to configure your model add the column to your OnModelCreating -Method in your DbContext. Please check this link for more information on how to configure the database-model.

UPDATE: Those extra-columns are generated by the Identity-server and should not be removed. Just apply the migration to the database and everything should work.
