Class Objects - Hierachy and Inheritance ( NOT WORKING)












0














I have a (People) or Users objects, of which I am using class inheritance to create the various objects.



However I am getting errors INVALID COLUMN, when I add the object, Users_Accounts which exist in the database with their respective columns below, I get the error



what am I doing wrong ?



ERROR MESSAGE
An unhandled exception occurred while processing the request.
SqlException: Invalid column name 'Users_AccountsAccountID'.
Invalid column name 'Users_AccountsAccountID'.
Invalid column name 'Users_PhonePhoneID'.



namespace Accounts.i_EF.Accounts
{
public class Users
{
[Key]
public int UserID { get; set; }
public string Email { get; set; }
public Guid UniqueID { get; set; }
public DateTime Dates { get; set; }
public bool IsSuspended { get; set; }


public Users_Accounts Users_Accounts { get; set; }


}
public class Users_Accounts

public string Email { get; set; }

public DateTime Dates { get; set; }
public bool IsSuspended { get; set; }
}
public enum Gender

}


and my controller code



 var user = HttpContext.User.Identity.Name.ToString();
var DataContext = _context.Users.Include(c => c.Users_Accounts);


return View(await DataContext.SingleOrDefaultAsync(c => c.Email == user && !c.IsSuspended));
