我如何在Cinemawebsiteuser模型之间建立一对一的关系，该模型从身份证模型中继承了另一个模型

在ASP.NET核心MVC中这是Cinemawebsiteuser模型的代码：

public class CinemaWebsiteUser : IdentityUser
{
    [Display(Name = "First Name")]
    [Required(ErrorMessage = "please enter your first name")]
    public string FirstName { get; set; }
    [Display(Name = "Last Name")]
    [Required(ErrorMessage = "please enter your last name")]
    public string LastName { get; set; }
}

这是其他模型的代码：

public class OrdersCart
{
    [Key]
    public int OrdersCartId { get; set; }
    
}

根据我的情况，FK必须在Cinemewebsiteuser模型中，因此我可以获取用户ID并使用orderscart模型进行ATACH。感谢任何帮助。

原文

In ASP.Net Core MVC
here is the code of CinemaWebsiteUser Model:

public class CinemaWebsiteUser : IdentityUser
{
    [Display(Name = "First Name")]
    [Required(ErrorMessage = "please enter your first name")]
    public string FirstName { get; set; }
    [Display(Name = "Last Name")]
    [Required(ErrorMessage = "please enter your last name")]
    public string LastName { get; set; }
}

and here is the code of the other Model:

public class OrdersCart
{
    [Key]
    public int OrdersCartId { get; set; }
    
}

and the FK must be in the CinemeWebsiteUser Model depending on my scenario, so i can get the user id and atach it with OrdersCart Model.
i will appreciate any help.

模型

public class CinemaWebsiteUser : IdentityUser
{
    [Display(Name = "First Name")]
    [Required(ErrorMessage = "please enter your first name")]
    public string FirstName { get; set; }
    [Display(Name = "Last Name")]
    [Required(ErrorMessage = "please enter your last name")]
    public string LastName { get; set; }

    public OrdersCart ordersCart { get; set; }

    public int OrdersCartForeignKey { get; set; }
}

public class OrdersCart
{
    [Key]
    public int OrdersCartId { get; set; }

    public CinemaWebsiteUser cinemaWebsiteUser { get; set; }
    
}

dbContext

// .....other code .....

protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        modelBuilder.Entity<OrdersCart>()
            .HasOne(b => b.cinemaWebsiteUser)
            .WithOne(i => i.ordersCart)
            .HasForeignKey<CinemaWebsiteUser>(b => b.OrdersCartForeignKey);
    }

结果：

Model

public class CinemaWebsiteUser : IdentityUser
{
    [Display(Name = "First Name")]
    [Required(ErrorMessage = "please enter your first name")]
    public string FirstName { get; set; }
    [Display(Name = "Last Name")]
    [Required(ErrorMessage = "please enter your last name")]
    public string LastName { get; set; }

    public OrdersCart ordersCart { get; set; }

    public int OrdersCartForeignKey { get; set; }
}

public class OrdersCart
{
    [Key]
    public int OrdersCartId { get; set; }

    public CinemaWebsiteUser cinemaWebsiteUser { get; set; }
    
}

DbContext

// .....other code .....

protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        modelBuilder.Entity<OrdersCart>()
            .HasOne(b => b.cinemaWebsiteUser)
            .WithOne(i => i.ordersCart)
            .HasForeignKey<CinemaWebsiteUser>(b => b.OrdersCartForeignKey);
    }

Result:
