But for the application this is really GET /cart_item/new/5 or even better /cart_item/new?cart_item[product_id]=5 When the customer clicks add_to_cart they POST /product/5/show so that the url doesn''t confuse the user when any validation errors occur. But for the applicaiton this should be POST /cart_item/create?cart_item[quantity]=23 Can I...

When I add an item to the shopping cart, I get an error: undefined local variable or method `cart_item'' for #<#<Class:0x3715a78>:0x3715a48> Session info says the cart being updated properly.

I recently got a copy of the second addition in PDF and got stuck on the Ajax portion using highlighting page 128. While trying to make my cart flash I got an RJS error when I click add to cart. I have gone back and made sure my code matched what was in the book but no help. I sent Dave an email and he rec''d this list. Anybody got any good links for troubleshooting Ajax or maybe have see

This might seem really simple to some but just wanted to ask: what is the difference between @session[''user''] and session[:user] ? and how would you use each? And another question, I have the following code: def get_customer if @session[''customer''] @c = Customer.find(@session[''customer'']) end end private def

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 post cartitem/create get cart see that product 4 in in the cart Thanks, Peter

...pp.com/projects/45560-acts-as-ferret/tickets/176-aaf-051-undefined-method-includes_values-for-conditionssymbol#ticket-176-4 Anyway, i fixed the query and moved on. Today I hit the error again but I do not have any include queries. It seems that rails is generating it. I have a cart that has many cart_items and a cart item belongs to a domain. When I try to access the domain in my cart view I get the ''includes_values'' error on this item (item.domain.id) <% @cart.cart_items.each{|item| %> <li id="cart_domain_id_<%=item.domain.id%>" class="cart-it...

...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 the for emptying the cart as it seemed to me that when I clear the cart I am operating on the items which is why I added that action to the CartItemsController. If this is not RESTfully "correct" I would love to...

Hi all, I have the shopping cart page where a user can add items dynamically through ajax as explained in Railscast episode 75. I am using observe_field to observe the ''quantity'' and ''cost'' fields to update the total field for each item. This does not work however, for records that are added through the Ajax. How can i name the fields and observe them as i have

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? This is in the StoreController and I believe it

Hi all, just joined and have only just kicked off with Rails (coming, but not departing, from WebObjects development). And so far there seems to be a lot of promise except for one thing I can''t figure out as yet -- the above problem. Say I have the following conceptual relationships: ITEMS <<--->> CARTS i.e., each item can belong to one or more categories. So really

I''m trying to implement a remove from cart method based on the examples in the second edition Agile book. I have everything working except for the RJS that removes items from the cart. Ideally what I''d like to do is highlight an element that I am deleting only if there is more than one of that particular item in the cart. If the item deleted is the only of

I''m thinking of experimenting with some currency conversion. However, I''d like the conversions to be in synch with the current rates. Anyone know (and this maybe out in left field) if there is some online (perhaps xml) or other data stream I can connect with in my code to output values based on user selection ? TIA Stuart
