Difficulty using "public virtual" variables in database creation - asp.net-mvc-3

Question

I am creating two tables in Visual Web Developer 2010 Express using the following code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
namespace BarApp.Models
{
public class Drinks
{
public int DrinksId { get; set; }
public int EstablishmentsID { get; set; }
public string name { get; set; }
public decimal price { get; set; }
public string description { get; set; }
public string image { get; set; }
public virtual Establishments establishment { get; set; }
}
}
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
namespace BarApp.Models
{
public class Promotions
{
public int PromotionsId { get; set; }
public string name { get; set; }
public float discount { get; set; }
public int EstablishmentId { get; set; }
public int DrinkId { get; set; }
public string description { get; set; }
public virtual Establishments establishment { get; set; }
public virtual Drinks drink { get; set; }
}
}
But when I look at the created tables, the Promotions table has actual rows for the public virtual code, whereas the Drinks table does not.
I am able to have the Drinks table function the way I want elsewhere in the project, but I cannot get Promotions to behave the same way because it appears that "public virtual" is giving different results in each table.
I do not understand why my Promotions table is actually creating rows for the public virtual variables. Can someone help me understand?

Answer 1

In this particular situation I was not using the conventional way of referencing the Id field of another table.
I simply needed to change the following:
public int EstablishmentId { get; set; }
public int DrinkId { get; set; }
to the following:
public int EstablishmentsId { get; set; }
public int DrinksId { get; set; }
My tables were created as expected after I made this change.
