I'm doing some editing on an existing rails app and this view;
_tour_listing.html.erb looks like this:
% if @upcoming_tour_requests.blank? %
pNo upcoming tour requests./p
% else %
table
tr
thGroup Name/th
thContact Name/th
thStatus/th
thDate/th
thActions/th

when you get the error mentioned above, there should be the rails

Here is the full trace:

Try changing this to

It might also be helpful to see my store_controller.rb file:
class StoreController ApplicationController
def index
@products = Product.find_products_for_sale
end
def add_to_cart
@cart = find_cart
product = Product.find(params[:id])
@cart.add_product(product)

I'm new to rails so I apologize for my ignorance in advance... I'm
working through a tutorial here but I think it may be written for a
slightly older version of rails. Trying to make a store app.
I'm getting the following error (with application trace shown):
ArgumentError in
Also, my add_to_cart.rhtml view looks like this:
h1The shopping cart/h1
ul
% for item in @cart.items %
li%= cart_item.quantity % times; %= h(item.title) %/li
% end %

You received this
StoreController#add_to_cart
-- doesn't expect any methods, but this is called by the Rails framework
as
an action, and Rails doesn't pass any arguments to the action methods
Cart#add_product
-- expects 1 argument, you're calling it with 1 argument in
StoreController#add_to_cart
Probably.
You could always add a parameter to your CartItem#initialize method.
I'm
not sure that you're heading in the direction you want to be heading,
since
it appears that CartItem is not derived from ActiveRecord::Base -- it's
not
tied to a database.

a Sorry I see now I was thinking that the CartItem class was an
activerecord class ... The issue is this:
Here you call a new object of CartItem with a product passed
@items CartItem.new(product)
But here in the initialize you do not have a argument for
initialize...
class CartItem

Where does the cart_item come from? is that in the Store controller?
post the store controller... The view has the @cart object but also
needs the cart_item.. Is that from the session?
cart_item.rb is the name of a model file, the one that starts with class
CartItem
I'm going through a tutorial here and running into an error I'm not sure
how to fix..this is my first foire into sessions.

So I have been tinkering with Rails all week - I'm a designer, not a
developer, but I'm looking to expand my knowledge. I created an instance
of Radiant, the cms, and am looking to fiddle with it and then try
putting it on a server.
I have the 'radiant project' created here:

Newbie here (who else.) I feel confident I can excel in the actual
programming of rails apps. But all the tutorials just glaze over mySQL
which seems to me, by far, the most problematic area for new users.
I have tried a ton of different things here. I know mySQL is installed

Which simply means MySQL isn't in your PATH. You need to find
where the MySQL executables are installed and add that directory

First, how do I add it to my PATH? Second, I used this to install mySQL:

I'd imagine that somewhere under /Applications/MAMP is a directory
