similar to: @session['user'] vs session[:user]

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

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

Hello, I am trying to set the protocol and host in link_to based on the documentation. I have the following: <%= link_to "View Cart", {:controller => ''store'', :action => ''view_cart'', :protocol => ''https://'', :host => ''secure.host.com''} %> I would expect this to generate a https link to another

I''ve posted a different question just before -- but before I can try and get a better idea of my error message, I was trying to start my application and ran into other problems. My application was developed last year in rails 1.2.3. I since upgraded my computer and have the latest version of rails. When I tried to star the application I got the following error message:

Hello all. I''m a noob at Ruby on Rails, only started learning a few days ago, but I''m loving it so far. I do have a few years experience with PHP, ASP, MySQL, etc., so I''m not *totally* clueless, though. :) Anyway, I''m having trouble with something that should be fairly trivial: I have an ''if'' statement that is supposed to print out a table

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

Hi all, I''m having trouble figuring out how to handle stock levels in a new store I''m building. When products are entered into the admin of the store, they have a stock number associated with them. What I''m not sure about, is how I go about maintaining this stock level. Take this scenario: 1. User A adds an item to their cart, and I check that it''s in stock -

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

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

Given this code (which renders rjs), I''m faced with the fixture- driven way of spec-ing or mocking. How the heck to you mock this so the code at line (2) and (4) work right? I''m still struggling with mocks but it seems like this can be done. Forgive the naivety of this question. 1. def change_quantity 2. @line_item = LineItem.find_by_id(params[:id]) 3. unless

I see in the new Agile Rails 2nd edition that components are going out of style? Is this so? has anybody abandoned the idea of components for helpers? Specifically I''m considering a menu sytem for a website that depends heavily on the users permissions to decide which menu options a user would need to see. I thought that components, since they have the logic in the controller and

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

In an early section on Action View, showing code being put directly into the rhtml file: <% require ''date'' DAY_NAMES = %w{ Sunday Monday Tuesday Wednesday Thursday Friday Saturday } today = Date.today %> <h1>Hello, Dave</h1> <p> It''s <%= DAY_NAMES[today.wday] %>. Tomorrow is <%= DAY_NAMES[(today + 1).wday %>. </p> I get this

Hi all, I am writing a simple shopping cart which will consist of a single class. There will be no DB table for carts so I do not want to make my Cart a model. But where do I place my Cart class so that I can access it in my controllers? I want to be able do do things like this (for instance in a shop controller): def add_to_cart @session[''cart''].add(article_id, amount)

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 am really enjoying the experience of writing my first web app in Rails. I particularly like the instant feedback the framework offers when developing in small increments and I am learning new things all the time. However since I develop alone and my inexperience with rails I?m asking for help to answer some design questions that I have regarding my first app. After reading the Agile

If I do get :index response.should_be_success I get about 20k of marshalled dumpage that starts like #<ActionController::TestResponse:0x390443c @body=\"<html><body>You are being <a href=\"http://test.host/carts/1\">redirected</a>.</body></html>\", @assigns=[], @redirected_to={:action=>\"show\", :id=>1},

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

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
