EF 4.1 - Model Relationships

Question

I\'m trying to create a quick ASP.NET MVC 3 application using the RC version of EF 4.1. I have two models:

public class Race
{
    public int RaceId { get; s         


        

Answer 1

It recognizes Id as the primary key by convention. So what you need to do:

public class Race
{
    [Key]
    public int RaceId { get; set; }
    public string RaceName { get; set; }
    public string RaceDescription { get; set; }
    public DateTime? RaceDate { get; set; }
    public decimal? Budget { get; set; }
    public Guid? UserId { get; set; }
    public int? AddressId { get; set; }

    public virtual Address Address { get; set; }
}
and

public class Address
{
    [Key]
    public int AddressId { get; set; }
    public string Street { get; set; }
    public string StreetCont { get; set; }
    public string City { get; set; }
    public string State { get; set; }
    public string ZipCode { get; set; }

    [ForeignKey("RaceId")] // Maybe telling it what the ForeignKey is will help?
    public virtual Race Race { get; set; }
}

The [Key] attribute indicates that it should be the PrimaryKey

If you don't want this, you need to rename your primary keys to simply public int Id {get; set; }
