similar to: YAML and has many associations

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 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

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

Hi, I need to download an image, and I''ve mucked about with Net::HTTP resp = Net::HTTP.get_response(''www.mydomain.com'', ''/test.jpg'') f = File.new("test.jpg","w") f.write(response.body) And various other combinations using HTTP.get etc. Anyway, I get an image, but it looks very psychedelic. This is obviously not the correct way.

Hi, I''ve developed a standalone Rails app - using tar2rubyscript and rubyscript2exe. The users aren''t going to understand that the''ll need to open the browser and go to 127.0.0.1:3000 to view the app, after running the exe. I am wondering whether other people have tackled this problem in the past, and how they went about solving it. One way would be to write a

I, I have an object and associations, say order and line_items. I want to submit this order and its lineitems to a central server using AWS. One way is to have an AWS method to submit the order object, and another method to submit each line_item individually (as I can''t have a typed array as an :expects parameters) - so I can''t submit all my line_items in one go. This is

Greetings again: I''m simplifying the case I presented earlier regarding the use of has_many :through. I''m using DHH''s example from "Persuing Beauty with Ruby On Rails". Here are his models: class Author < ActiveRecord::Base has_many :authorships has_many :books, :through => :authorships end class Book < ActiveRecord::Base has_many

Hi, I want to make a copy of an object with its associations, and I am looking for an elegant solution. This is what I intuitively think should work, but it doesn''t: order2 = order1.clone order1.line_items.each do |o| order2.line_items.build(o) end This doesn''t work because a model class does not stringify its keys ... so I can''t pass an object into a method that

I''m trying to figure out an elegant way to do this: I have the following three tables: people, employer, employees And consequently the following three models: class Person < ActiveRecord::Base end class Employer < ActiveRecord::Base has_many :employees end class Employee < ActiveRecord::Base belongs_to :person belongs_to :employer end I want to be able to say:

I have the following association class Document < ActiveRecord::Base has_many :sections has_many :items, :through => :sections end class Section < ActiveRecord::Base belongs_to :document has_many :items end class Item < ActiveRecord::Base belongs_to :section end Here is the sample view for the ''new'' action <% form_for(@document) do |f| %> <%=

Anyone have a more extensive yaml file for jqgrid than the one that''s shown with the example Jqgrid Demos page? Also, I''ve been successful in just using the straight jQuery javascript code, rather than invoking the yaml file to produce it), but sometimes get an "unitialized class variable @@grid_name" error.

Hi friends: I tried to convert a model object to yaml(use to_yaml method), and after that, I would like to convert the yaml(string type) back to the model object. But when I use YAML::load to do that, it failed, the return object''s class is Yaml class, not my prior model class.. Please tell me how can I do to convert yaml to an object as the prior model class, or how can I access the
