anyone can explain me why in the Agile Depot Tutorial application they use i.product_id to find if a product already exist in the cart, because the cart contains items, each of them references a product.

I''m new in Rails, and I''m building my first application. I''m trying to make a FAQ for this application, organized by product (questions about each product) and category (questions of different categories or topics), and there is something I can''t figure it out how to do. I have these tables: create_table "faqs" do |t| t.column "question",

What is the most elegant way to save new one-many associations? order = Order.new(:name => "My Order") order.line_items << LineItem.new(:product_id => 1, :quantity => 2) order.line_items << LineItem.new(:product_id => 2, :quantity => 5) order.save The above - which is by far the most elegant way of putting it - doesn''t work for me - the line_items

Hello, I am new to ruby on rails. When I tried to create a session I am getting an error, ''wrong number of arguments (1 for 0)'', in my controller. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ArgumentError in CustomerController#add_to_cart wrong number of arguments (1 for 0) RAILS_ROOT: /project/bob_shopping Application Trace | Framework Trace | Full

...TM association declared in the model will save during the initial @order.save in the create action in my orders_controller.rb code below. If the order is then updated via an edit action, all selected associations will save correctly. If you notice in the development.log dump, I''m passing product_ids and loan_type_ids arrays back to the controller properly. Inspecting the @order object during a breakpointer session shows the related object are available for saving, but for some reason, ActiveRecord does not want to save the second association class at the beginning. Any ideas what I''...
