一個用流利的API一個關係

Question

型號：

public class User { 
    public Guid UserId { get; set; } 
    public string UserName { get; set; } 
    public virtual Membership Membership { get; set; } 
} 

public class Membership { 
    public Guid UserId { get; set; } 
    public DateTime CreateDate { get; set; } 
} 

的DbContext：

public class UsersContext : DbContext { 
    public UsersContext() : base("ApplicationServices") { } 
    public DbSet<User> Users { get; set; } 
    public DbSet<Membership> Memberships { get; set; } 

    protected override void OnModelCreating(DbModelBuilder modelBuilder) { 
     modelBuilder.Entity<User>().ToTable("aspnet_Users"); 
     modelBuilder.Entity<Membership>().ToTable("aspnet_Membership"); 

     //insert relation here to join the two tables 
    } 
} 

這是我第一天用流利的API玩耍，我只是想知道我怎麼將能夠加入這兩個表格。我將如何定義關係？

另外，流利的API的任何教程已經幫助你？

Answer 1

你可以使用下面的代碼示例：

modelBuilder.Entity<User>() 
       .HasRequired(u=>u.Membership) 
       .WithOptional() 
       .HasForeignKey(u=>u.UserId)
