I''m developing a rails application. I have an Order model that has_many OrderItems. I mocked the OrderItem model in my Order specs using mock_model. I thought I should focus my specs on each model and always mock associated models. In my Order model I need a way to merge OrderItems which have the same cost and same product_id. That I can spec. The other thing this merge help...

...er items as part of the order, so I''ll explain the problem in those more familiar terms and then explain what if anything makes my actual situation different at the end. In an Order lets say you have: shipping_address and a shipped bool. OrderItem has quantity and name So Order has_many :OrderItems, and OrderItem belongs_to :Order It''s pretty easy to make it so you can create an Order then go to another URL and create a OrderItem and associate (say with a select) the Order the OrderItem belongs to, and so on. What I really want though is the ability to have users click to create an...

I seem to be missing something trying to use ''validates_inclusion_of'' to validate a foreign key and was hoping some one could piont out my mistake? The problem seems to be that Order.find_all.collect is not returning an array that contains the order_id, if I replace it with a hardcoded array everything works as expected. The model: class OrderItem < ActiveRecord::Base

Hi all, I''m following the shop example in ''Agile Web Development with Rails''. I would like to extend the checkout screen, in such a way people can change the number of items they have selected in there cart. In my controller I have: def checkout @cart = find_cart @items = @cart.items if @items.empty?

I''m setting up a basic shopping cart type app, and the products we have will have multiple options. Size, color, etc. I''m trying to figure out how I can collect the the options that are selected when a user adds the item to their cart. An OptionSet is a group of options ("Size", "Color", etc), and an ItemOption is the option itself ("12 oz",

Is there a way for me to do: OrderItem.find(:all, :include => [:user, :product => [:supplier]] So I don''t have a supplier_id on my order_item, but have it on my product, which is part of order_item. Joerg -- Posted via http://www.ruby-forum.com/.

...ilitzation goes up to almost 70%. A simpler application where I just use plain xml in the request and response, and use a bit of to_xml and REXML for building the trees still takes a good amount of memory but nowhere near the amount of cpu. The data is from 3 tables. Customers, transactions, and orderitems. I created a struct for customers and in customers there are two members that contain a struct for transactions and orderitems. Right now the code looks like this. Any ideas on how to optimize it? Or even ideas on better methods then using soap for something like this? @orders = Customer.find(:a...

I have orders, order_items, and products. I want to collate several orders so that I can get a SUM of quantities ordered for each product etc. Can I say something like (the below gives an error on :sum, and ignores :group) OrderItem.find(:all, :sum => ''quantity'', :group => ''product_id'', :include => [:order, :product]) I want to get back a
