...ng 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?

I''m trying to set up the Depot app from Agile Web Development and I got this error after C1 - Creating a Cart. The exact error looks like this: ------------------------------------------------------------------- NoMethodError in StoreController#add_to_cart You have a nil object when you didn''t expect it! You might have expected an instance of Array. The error occurred while evaluating nil.<< E:/InstantRails/rails_apps/depot/app/models/cart.rb:9:in `add_product'' E:/InstantRails/rails_apps/depot/app/controllers/...

Working through the Agile Web Development w/ Rails book on p114. I can add single items of each to the cart but when I try to add a second item I get the following error: NoMethodError in StoreController#add_to_cart You have a nil object when you didn''t expect it! You might have expected an instance of Array. The error occurred while evaluating nil.+ Any idea why this is happening? Thanks. Frank. -- Posted via http://www.ruby-forum.com/.

Hey everybody, I am currently following the depot application from the book Web Agile Development with Rails (3rd Edition) but after creating the controller for the Store and the Cart model, I am always getting a nil product, no matter how many products I add to the database. I am very new with RoR (this only the page 110 of the book) and thus I am not very sure about what I could do to mitigate

...rom Apachefriends XAMPP. Here is a snippet of the log file, where I add an item to an empty cart and then show the order page. You can see where I noticed something odd below. It appears that the cart is not getting loaded in display_cart() when in the context of the order page: Processing StoreController#add_to_cart (for 127.0.0.1 at 2006-04-20 02:02:07) [GET] Session ID: 90352668088f989d5f939978b52b2a3a Parameters: {"action"=>"add_to_cart", "id"=>"4", "controller"=>"store"} Product Load (0.132395) SELECT * FROM produ...

Hi there I''ve also made a start on the Agile Web Dev using Rails book! I''ve been hit with a problem when hitting the ''Add to Cart'' button - I get the following error message: ActiveRecord::RecordNotFound in StoreController#add_to_cart Couldn''t find Product without an ID RAILS_ROOT: ./script/../config/..

...at 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 app/models/cart.rb:15: parse error, unexpected $, expecting kEND Not sure where to turn to figure this out being a newb.

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 @new_item.valid? @cart.items << @new_item # execute add_item.rjs else breakpoint...

I am actually following the instructions/code snippets from "Agile Web Development with Rails" and got as far as page 73 where I did ruby script/generate controller Store index, then edited store_controller.rb to class StoreController < ApplicationController def index @products = Product.salable_items end end and product.rb to: def self.salable_items find(:all, :conditions => "date_available <= now()", :order => "date_available desc") end but it keeps showing this...

...(first edition). However, I''ve come across a problem which has had me stumped for days now. After following the instructions up to page 85 I have tried testing the code thus far, as suggested, by adding an item to the cart.

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.
