entity-framework-5 - How do you save table with foreign key relation using Entity Framework 5.0

Question

I am using entity framework 5.0 and I am not able to save tables with foreign key relation. I have a table called "Order" (OrderID & Date) and a table called "OrderLine" (Price,ID,OrderID). With the Following code, I am unable to save OrderLine. System just saves data in Order table.

  using (var db = new DartProjectionsDb())
            {
                var view = new Order
                {
                    OrderID = e.Identity.Identifier,
                    Date = SystemTime.UtcNow(),

                };

                     OrderLine orderLine = new OrderLine();

                     orderLine.ID = 1;
                     orderLine.OrderID = e.Identity.Identifier;
                     orderLine.Price = 100;


                     view.OrderLines.Add(orderLine);

                db.Orders.Add(view);
                db.SaveChanges();
            }

Answer 1

次のようにオーダーラインをデータベースに追加してみてください:

db.OrderLines.Add(orderline)

しかし、私は EF が舞台裏でそれを行うことを期待していたでしょう。
