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''m just not able to output two variables: <%= cart_item.quantity %> &times; <%= h(cart_item.title) %> I did some research, and I can grasp that local

Hi, I''m really excited about getting the create() method working on a nested hash. The Rails book make it seem like I''m close to doing the right thing but I think something very small is not quite right. The error at the below isn''t giving any hints that I understand. I have a form that produces a nested params hash and sends it to my add_to_cart controller method.

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

Hi - another question, sorry.... I''m trying to get the highlighting effect to work on the current_item. The page refreshes fine, and then I get an error as the highlighting code is fired: page[:current_item].visual_effect :highlight, :startcolor => "#88ff88", :endcolor => "#114411" The error

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. ArgumentError in StoreController#add_to_cart wrong number of arguments (1 for 0) #{RAILS_ROOT}/app/models/cart.rb:15:in `initialize'' #{RAILS_ROOT}/app/models/cart.rb:15:in

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

Rails 3 / Ruby 1.9.2 Over the weekend I saw the "undefined method `includes_values'' for :conditions:Symbol" error for the 1st time while working with AAF. http://j-k.lighthouseapp.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

Dear all, Help me get a simple AJAX behavior right. I know zero AJAX, thus please advice. Below is a simplification of the real code and I hope I can describe my intention clearly. class StoreController < ApplicationController def show_cart @cart = Cart.new @new_item = CartItem.new end def add_item @new_item = CartItem.new(params[:new_item]) if

First of all id like to say hi to everyone from Argentina, im yet another Depot first-timer. Going through the example, i got to the point where my cart finally runs Ajax-based. And there is a line where Dave says, after all the job is done "You should see the cart in the sidebar update. And you shouldn''t see your browser show any indication of reloading the page. You''ve

The question is, should we deal with Controller and Action logic in the RJS file? If so, is it quite "spaghetti-like"? This is actually for the Agile Web book Shopping Cart example: If the user clicks "Remove Item" and we do it the AJAX way, what if we want to first show the cart''s content as 0 x Pragmatic Version Control $0.00 and then highlight

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

Is there a way to specify a different log file for requests to a specific controller? For example, all requests to CartController would get logged to cart.log. Thanks in advance.

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

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 have been working through the Agile Web Development with Rails book doing the Depot tutorial. I have completed it and it works but I cant say I understand how and why. My question is this "After adding products to the Cart, how do I then give users the option to delete just one item and not empty the whole cart?" I''ve been playing around with all sorts of code, just making

All, I''ve just started Rails and Ruby a week or so ago. Please forgive me for my ignorance. I started writing a small test application to test some of my new knowledge and have hit a wall. Would like some best practices. I have 3 tables, as below... CREATE TABLE `carts` ( `id` int(11) NOT NULL auto_increment, `name` varchar(255) NOT NULL, `quantity` int(11) NOT NULL, PRIMARY

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
