How to use "one to many" relations in SubSonic - subsonic

Question

What are the ways to tell SubSonic about the relationship (only foreign keys? Or other methods too)?
If I have (for example) a team object with related team members
** how do I access and update the team members from the team
** how do I update the team members? Does saving the team object saves the team members changes
** How do I add members to the team? Do I just create a new member, assign the team ID to the foreign key and save? Or is there a more object oriented way (e.g. team.Add(teamMember))

Answer 1

Subsonic code generation will read the foreign key relationships in the tables and create the required helper methods in the table classes. The Northwind Product class has a PrimaryKey relationship to the OrderDetail class. Subsonic generates the method
public Northwind.OrderDetailCollection OrderDetails()
to get the OrderDetail rows as an OrderDetailCollection. This is a BindingList that you can change as needed, and call SaveAll() to save the list. There is no deep saving, so saving the Product won't save related OrderDetail rows.
[Test]
public void Demo_Product_OrderDetails()
{
Product product = new Product(3); // Read an existing row.
OrderDetailCollection orderDetails = product.OrderDetails();
Assert.IsTrue(orderDetails.Count == 12);
foreach(OrderDetail orderDetail in orderDetails)
{
orderDetail.Discount -= 0; // Do something meaningful.
}
OrderDetail newDetail = new OrderDetail();
newDetail.ProductID = 3;
newDetail.OrderID = 10248;
newDetail.UnitPrice = 7.00m;
newDetail.Discount = 0.10f;
newDetail.Quantity = 12;
orderDetails.Add(newDetail);
orderDetails.SaveAll();
orderDetails = product.OrderDetails();
Assert.IsTrue(orderDetails.Count == 13);
OrderDetail.Destroy(newDetail.OrderID);
orderDetails = product.OrderDetails();
Assert.IsTrue(orderDetails.Count == 12);
}
