Errors and Forms with arrays
Hello again-
I have a form with array information (like, say, items in a shopping
cart). Each item has several fields (quantity, for example).
Is there a nice way to specify the tags so that:
1. Data is extracted easily. They could be listed as "cart.items", for
example, but how to bring the updated data back into the array of
"items" without having to manually stuff

Design question: Storing user fields
Hello-
I have a database/rails design question. I''d like the user to be able
to specify a set of fields they would like associated with items.

items. (it will be site-wide, so every item listed for this particular
user will have this

"Agile Programming..." book. I went through the shopping cart (depot)
tutorial
without any problem. However, I would like to change the cart so that

NoMethodError in Agile Web Devleopment Depot Tutorial
I''m working on building the shopping cart in the Depot tutorial in the

/store/display_cart/ and it seems items are being added, but if I just
click on a link to add an item (/store/add_to_cart/2) it gives me this:
