Asp.net mvc 4款外键型号

Question

I have these tables:

public class udb:DbContext
    {
        public DbSet<klasa> Keuni { get; set; }
        public DbSet<student> Seuni { get; set; }
 }
  public class student
    {
       [Key]
        public int studentid { get; set; }
        public string emristudent { get; set; }
        public int nota { get; set; } 
        [ForeignKey("klasaid"), Column(Order = 0)]
        public int klasaid { get; set; }
}}
 public class klasa
    {  [Key]
        public int klasaid { get; set; }
        public string emriklases { get; set; }
        public string vendodhja { get; set; }
        public virtual ICollection<student> students { get; set; }
}

The problem is that I want the klasaid to be a foreign key in students so when the user adds a new student the klasaid should exist in klasa model.I use Asp.net mvc 4.Can sb help me?

It should look like this:

public class student
{
        [Key]
        public int studentid { get; set; }
        public string emristudent { get; set; }
        public int nota { get; set; } 
        public int klasaid {get;set;}

        [ForeignKey("klasaid")]
        public klasa Klasa{ get; set; }
}

You can use various database initialization strategies as follows:

public class udb:DbContext
{
        public udb()
        {
          Database.SetInitializer<udb>(new CreateDatabaseIfNotExists<udb>());
        }

        public DbSet<klasa> Keuni { get; set; }
        public DbSet<student> Seuni { get; set; }
}

One suggestion- follow proper naming conventions . Please, have a look into this link for more details.
