Question

i have these two models

    public class Group
    { 
    [Key]
    public int GroupID { get; set; }

    [Required]
    public string GroupName { get; set; }
}


public class User
{
    [Key]
    public int UserID { get; set; }

    [Required]
    [StringLength(20)]

    public string UserName { get; set; }

    [Required]
    public string Password { get; set; }   
    public virtual Group Groups { get; set; }
}

using code first approach it creates Groups_GroupID as the foreign key in the user table when it generates the database. Specifying GroupID with displayname didn’t work either because it is creating the same name.so how would i make it generate GroupID in the User Table? i am using EF 4.3

Answer 1

Use the ForeignKey attribute on the navigational property

public class User
{
    [Key]
    public int UserID { get; set; }

    [Required]
    [StringLength(20)]

    public string UserName { get; set; }

    [Required]
    public string Password { get; set; } 

    [ForeignKey("GroupId")]  
    public virtual Group Groups { get; set; }
}
