Question

I 3表：用户， Ref_League_name 和联结表 User_Leauge 我的用户表存储用户数据。我想创建一个表单，在用户登录后，该用户可以使用其用户ID选择联赛。我还想在User_league表中存储userID和LeagueID（用户选择的）。如何创建控制器和User_league的视图以更新联结表（User_league）中的userID和LeagueID？这是代码：

用户表：

 namespace NFL_WebApplication_V2.Models
{
    using System;
    using System.Collections.Generic;

    public partial class User
    {
        [System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Usage", "CA2214:DoNotCallOverridableMethodsInConstructors")]
        public User()
        {
            this.User_League = new HashSet<User_League>();
        }

        public int UserID { get; set; }
        public string FirstName { get; set; }
        public string LastName { get; set; }
        public string EmailID { get; set; }
        public Nullable<System.DateTime> DOB { get; set; }
        public string PWS { get; set; }

        [System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Usage", "CA2227:CollectionPropertiesShouldBeReadOnly")]
        public virtual ICollection<User_League> User_League { get; set; }
    }

Ref_league_name

namespace NFL_WebApplication_V2.Models
{
    using System;
    using System.Collections.Generic;

    public partial class Ref_League_name
    {
        [System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Usage", "CA2214:DoNotCallOverridableMethodsInConstructors")]
        public Ref_League_name()
        {
            this.User_League = new HashSet<User_League>();
        }

        public int LeagueID { get; set; }
        public string LeagueName { get; set; }

        [System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Usage", "CA2227:CollectionPropertiesShouldBeReadOnly")]
        public virtual ICollection<User_League> User_League { get; set; }
    }
}

User_league

namespace NFL_WebApplication_V2.Models
{
    using System;
    using System.Collections.Generic;

    public partial class User_League
    {
        [System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Usage", "CA2214:DoNotCallOverridableMethodsInConstructors")]
        public User_League()
        {
            this.UserLeague_Week = new HashSet<UserLeague_Week>();
        }

        public int ID { get; set; }
        public int UserID { get; set; }
        public int LeagueID { get; set; }

        public virtual Ref_League_name Ref_League_name { get; set; }
        public virtual User User { get; set; }
        [System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Usage", "CA2227:CollectionPropertiesShouldBeReadOnly")]
        public virtual ICollection<UserLeague_Week> UserLeague_Week { get; set; }
    }
}

请帮助，我是MVC新手，非常感谢
