EntityFrameWork SaveChanges Error - asp.net-mvc

Question

I am trying to make changes to a database by using Entity Framework (code-first). Everything works fine up until I attempt to save changes, when an error is thrown:
Invalid Column Name BasketID
However, during debugging, looking at the storeDB.BasketItems, the basketitem was actually added.
What am I missing ?
Code:
// Basket is ENTIRELY Empty, add new item and move on.
if (storebasket == null || storebasket.BasketItems.Count == 0)
{
// Add item as is
BasketItem newItem = new BasketItem
{
sellerSKU = basketItem.sellerSKU,
BasketID = basketID,
sellerID = 1,
Quantity = basketItem.Quantity,
Price = basketItem.Price
};
storeDB.BasketItems.Add(newItem);
storeDB.SaveChanges();
}
Database entity:
public class StoreEntities : DbContext
{
public DbSet<Order> Order { get; set; }
public DbSet<OrderItems> OrderItems { get; set; }
public DbSet<Basket> Basket { get; set; }
public DbSet<BasketItem> BasketItems { get; set; }
}
Classes:
public class Basket
{
[Key]
public string BasketID { get; set; }
public virtual IList<BasketItem> BasketItems { get; set; }
public System.DateTime DateCreated { get; set; }
public Guid UserID { get; set; }
}
public class BasketItem
{
[Key]
public int BasketItemID { get; set; }
public virtual string BasketID { get; set; }
[Required]
public int sellerID { get; set; }
[Required]
public string sellerSKU { get; set; }
[Required]
public int Quantity { get; set; }
[Required]
public decimal Price { get; set; }
}
OP pasted Edit as Answer:
I have no idea why this fixed the problem, but the program works as expected now
public StoreEntities(): base("storeDBConnectionString")
{
Database.SetInitializer<StoreEntities>(
new DropCreateDatabaseAlways<StoreEntities>());

Answer 1

If you Look at your BasketItem class you set your BasketID as virtual... That causes entity framework not to bind the property to a column. The correct way to do it would be :
public class BasketItem
{
[Key]
public int BasketItemID { get; set; }
public virtual Basket Basket { get; set; }
public string BasketID { get; set; }
[Required]
public int sellerID { get; set; }
[Required]
public string sellerSKU { get; set; }
[Required]
public int Quantity { get; set; }
[Required]
public decimal Price { get; set; }
}
