Direct To Web takes an eomodel and creates Web pages that support
fetching, inserting, deleting, and updating objects. But these pages
are usually not exactly what a developer wants to end up with, so they
must usually be customized. For someone new to WO, concentrating on a
traditional WO app might be a better way to start. You'll probably
learn more by creating your own Web pages yourself at first.
-Is there a sample shopping cart for WO available somewhere to see how
it works?
Because a shopping cart page is usually designed specifically for the
intended use, a generic shopping cart implementation may not be too
useful.
Basically, a shopping cart can be implemented by declaring in your
Session class a NSMutableArray instance variable with appropriate
accessor methods (e.g., addToShoppingCart(), removeFromShoppingCart(),
shoppingCart()). Then in each page in which objects can be added to
the shopping cart, invoke
((Session)session()).addToShoppingCart(anObject). You would also
include a ShoppingCart page that displays the shopping cart items in a
WOTable with a WORepetition that adds a table row for each object in
((Session)session()).shoppingCart(). The shopping cart table's columns
would display attributes of the object (e.g., description, price) that
would allow the customer to identify each object. You would also want
to be able to specify the quantity of each item, be able to delete
items, recalculate the total price, etc. This isn't difficult to
implement in WO.
