Depot - How to change the Store to a Form based application?
Hello,
I''m just getting started with Ruby on Rails. Of course, I bought the
"Agile Programming..." book. I went through the shopping cart (depot)
tutorial without any problem. However, I would like to change the cart
so that
one can enter a quantity for each item desired.
Has anyone else tried to do this?
Can anyone point me in the right direction?
Thanks!
Brad

/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:

Help with the Agile Depot application tutorial
anyone can explain me why in the Agile Depot Tutorial application they
use i.product_id
to find if a product already exist in the cart, because the cart
contains items, each of them references a product.
I tried i.product_id like in the tutorial
and
i.product.i
all of these 2 notation works , but i find the second seems more
clean??? isn''t it.
Any explanation will be fine
