I need some help to display products thats in one specific category. mysql> select * from products where category = "jackets" does what I want, but I?m not sure how to make a list and display it in rails?

In the agile/rails tutorial book the following construct is added to products.rb. def self.salable_items find( :all, :conditions => "date_available <= now()", :order => "date_available desc") end Now, I wish to extend :conditions => to exclude products that have a nil value for the price.

In the Agile Rails tutorial I am revisiting building a cart. I have followed the steps given in the book to create the class ''Cart'' thus: class Cart attr_reader :items attr_reader :total_price def add_product(product) @items << LineItem.for_product(product) @total_price += product.price end def initialize @items = [] @total_price = 0.0 end

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
