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 is kind of frustrating (but no doubt helpful in the long run) that 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

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 - 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

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

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, 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, A store front a customer wants to GET /product/5/show. 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

I want users to have their own landing pages: http://username.domain.com. Since this is dynamic (any user will have a subdomain), is there a way to do this without creating a DNS record for each of them? Can you DNS records be dynamic? -- Austin Govella Thinking & Making: IA, UX, and IxD http://thinkingandmaking.com austin.govella-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org

To reverse a migration that sets a default value, do you set the default to nil? And, if you''re setting a couple of default values just to make early development easier, is it best to do that directly to the database and not clutter your migrations with them? (I.e., it''s not a *real* db change.) Thanks, -- Austin Govella Thinking & Making: IA, UX, and IxD

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

Running with WEBrick, I seem to be occasionally getting these odd "uninitialized constant XXX" errors. Where the XXX is the first class that whatever action I run uses (e.g. Product, CartItem etc). >From the backtrace, it looks almost like the server is somehow trying to reinitialize? Any thoughts?

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

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
