similar to: Creating multiple option groups

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 helper

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?

Hi: I''m trying to create a drop-down list to change the type of a Single Table Inheritance class. I tried this: <%= select :user, :type, [ [''Author'', ''Author''], [''Editor'', ''Editor''], [''Administrator'', ''Administrator''] ]

I suspect my problem is similar to having an order and wanting to have order 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

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/.

I have hinted in the past of wanting to go to a more selective control of the output of rsync. Here it is. PROBLEMS with the existing --verbose et al. The simple incrementing verbose doesn't allow one to restrict stdout to what actually is of interest. For instance inside dirvish i don't care about directories, or any kind of non-regular file because they show up every time even if

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

I have the following view template: <%= form_remote_tag :update => "new_item", :url => {:action => ''create''}, :before => %(Element.show(''spinner'')), :success => %(Element.hide(''spinner'')) %> <div id="new_item"> </div>

I have read extensively on has_many but cannot find an explicit example on how to do what I need. I am a newbie, but can grasp it if I see it in a working example. Here is my scenario... I have a form which I can add a TODO item (patterned after http://darkhost.mine.nu:81/~vince/rails/tutorial.html). I have the form working perfectly so I decided to modify it a bit to add more functionality.

hi, I''ve got the following tables in mysql notation: CREATE TABLE `nodes` ( `id` int(11) NOT NULL auto_increment, `parent_id` int(11) default ''0'', `group_id` int(11) default ''0'', PRIMARY KEY (`id`), ); CREATE TABLE `groups` ( `parent_id` int(11) NOT NULL default ''0'', `id` int(11) NOT NULL auto_increment,

Hello, I''m trying to use Nicedit to improve my text_areas in some views of my project.

I'm running a bit late with the e-mail this time around, but I think that's ok since there really isn't any major new features here - the bulk of the Ocfs2 update is bug fixes, or cleanups. The same goes for configfs. The only two things that could be described as features would be: - Sunil has updated Ocfs2 to provide even more live cluster locking information via debugfs. - Joel

Hi, Jarkko: Thanks for the quick reply. I understand I can use ActiveRecord to specify the relation between the table as you have suggested, The part that I have trouble to understand is 1. Since I have a third table ProvWorkAtDept, do I need to specify this table somewhere when I define Provider or Dept? 2. If the provider view has both the provider name and several depts the provider

I''m trying to provide our customers with a page where they can add up to 20 items to their cart in one form. The form simply has 20 rows with each row containing a text input for product code and a text input for quantity. I''ve tried having the controller create an array that has an object for each row by looping through something like: @new_items[1] = Cart.new and the

Dear all, Help me get a simple AJAX behavior right. I know zero AJAX, thus please advice. Below is a simplification of the real code and I hope I can describe my intention clearly. class StoreController < ApplicationController def show_cart @cart = Cart.new @new_item = CartItem.new end def add_item @new_item = CartItem.new(params[:new_item]) if

I''ve been playing around with a soap interface to an application that can return large datasets (up to 50mb or so). There are also some nested structures for which I''ve used ActionWebService::Struct with 2-3 nested members of oher ActionWebService::Struct members. In addition to chewing up a ton of memory, cpu ulilization isn''t that great either. My development
