similar to: Instance variable?

Hi I am new to the whole Rails/Ruby world as having come from a MS .NET background, but I have followed the Depot example in the Agile Web Dev. with Rails book with relative ease. However as an exercise to see how much I had understood, I thought I would attempt to modify the example a bit and add a Quantity field to the store index so as to pass that value into the cart. I have extended the

I am using this line on my index.rhtml page to capture the quantity required of a particular item for a basic shopping cart app: <%= text_field ''line_item'', ''quantity'', {:size=>3} %> </td> but my next screen (a cart screen) doesn''t reflect what was entered in that text field when the item is added to the cart. That is,

Hello. I''m using the Agile Web Dev. book 1st Edition and I''m puzzled by the code on pp. 83-84. <%= link_to ''Add to Cart'', {:action => ''add_to_cart'', :id => product }, :class => ''addtocart'' %> def add_to_cart product = Product.find(params[:id]) @cart = find_cart

I''m trying to grab a CSV file from a user and let them upload it directly to my database, but doing some minor checks on the data before saving. Which is the easier way to implement this? CSV or FasterCSV? I saw that perhaps there were some issues with FasterCSV and csv files created from Mac versions of Excel. Anyone have any experience with this and can recommend a newbie friendly

I have a template that is called by two different methods. I only want part of it too show up when it is called from one of the methods. It always shows up for me.

Below is the method that should keep part of the tempate from printing, and the relevent part of the template. method: def gallery @product_pages,@products = paginate(:products,

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 have looked at examples for this. I found a similar example in the Agile Web Dev... book but that didn''t help. Here''s what i am trying to do. A Cart has many line items. On the Display Cart page, I want to provide the user the option to update quantities. Here''s the rhtml code: <%= start_form_tag :action => ''update_cart'' %>

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 want to modify and update the items in the Depot - "display_cart". Since the cart is in a session, its a little hard to get at the data. I just want to create a way to change quantities, prices and recalculate. Has someone done this, and could you point me to the right direction. Thanks Chas -- Posted via http://www.ruby-forum.com/.

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, im looking to build a page similar to a shopping cart page. When you change the ''price'' or ''quantity'' fields, the total is calculated and displayed. There are other fields in the form which have no relation to this action. So i guess observe_form is not required. Can someone tell me what the best practise is for this?
