update or alter cart
I want to modify and update the items in the Depot - "display_cart".
Since the cart is in a session, its a little hard to get at the data.
I just want to create a way to change quantities, prices and
recalculate.
Has someone done this, and could you point me to the right direction.
Thanks
Chas

Agile Web Dev (book) question: errors
This is kind of frustrating (but no doubt helpful in the long run) that
after following along and coding , and d/l the code the same error is
appearing.
For those who are familiar with the depot app, I''ve run into a problem after
fixing the cart to reflect quanitites. I worked through the intended error
messages but now have this appearing:
SyntaxError in StoreController#add_to_cart

The Depot "Add to Cart" sessions question (2.ed agile book)
Hello,
Im in the process of working my way through the 2.ed of the agile book.
As many of you already know, the book goes through the regular
development cycle of the Depot application. I have hit a wall
when they started talking about the sessions and the exact mechanics of
how an item is added to the session.
The code looks like this:

Agile Depot Tutorial Help
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
