Newbie error: undefined local variable or method
When I add an item to the shopping cart, I get an error:
undefined local variable or method `cart_item'' for

Session info says the cart being updated properly. I''m just not able

I did some research, and I can grasp that local

Errors ... errors and errors.
I bought the second edition of the ruby on rails, it seems to work fine
now, did some adjustments to the code. But now I get a second error and
I want to learn to understand to fix them myself. So here is the error.

REST help
Hi all,
I am trying to build a RESTful shopping cart and I have hit a small
wall, but before I get to that let me explain what I have done thus far.
I have two RESTful controllers, CartController and CartItemsController
with a nested routes setup like so
map.resources :carts do |carts|
carts.resources :cart_items, :collection => {:empty => :delete}
end
(I added a custom route to

Error on update_attributes with HABTM relationship
Hope someone can tell me what''s up, because this has me baffled.
I have an Image model, and a Provider model. Both are defined as
"has_and_belongs_to_many" relating to each other. In my image form
partial, I have a bit of AJAX generating the provider_ids array
dynamically from a provider AJAX search on the same page.
So for example, each time I click on a provider name that

cross controller functional tests?
Hi,
I have an online store and I would like to simulate a complete
shopping trip which involves several controllers? How can I write a
test that calls actions from different controllers in a particular
sequence? Something like the following which involves department,
product, cart_item, and cart controllers.
get department 5
check it has a link to product 4
get product 4

Enumeration sum
Any idees why I can do this:
@sum = @selected.inject(0) { |sum, player| sum + player.value }
but not this:
@sum = @selected.sum { |player| player.value }
@sum = @selected.sum(&:value)
The last two give me following error:

type mismatch because of misled array index
Most times I look up a list of books I want to know a page reference for
each one, so the views that display booklists expect an array of
two-element arrays, constructed via a method in the model like so:
(class Category)
def book
@book = Array.new
self.bookshelves.each { |x| @book << [x.book, x.pages] }
return @book
end
When I get the list of all books that a user has

I am really new to Ruby and Rails but as you probably see I am trying
to get the shopping card working from the book. I am getting this
error but I really don''t know what to do. I have looked up several of
topics that stated the same problem but as far as I am, nothing has
helped me out yet. Is there something wrong with the Product model?
