Polymorphic Data Modelling Question
...ituation in Rails and would appreciate some guidance. An order can hold multiple line items. Each line item is for a certain number of any given product. There are four products, each in a different table because they have completely different attributes. So I have: Order - has many LineItems LineItem - belongs to an Order - holds the quantity of the particular product - has one {ProductA or ProductB or ProductC or ProductD} ProductA - belongs to many LineItems - holds various attributes unique to product A ProductB - belongs to many LineItems - holds various att...

How To Spec Controllers with Finders
Given this code (which renders rjs), I''m faced with the fixture- driven way of spec-ing or mocking. How the heck to you mock this so the code at line (2) and (4) work right? I''m still struggling with mocks but it seems like this can be done. Forgive the naivety of this question. 1. def change_quantity 2. @line_item = LineItem.find_by_id(params[:id]) 3. unless

Legacy system belongs_to problem
Hi all, I am trying to patch a small rails app into a large system we have at our company. The legacy has a large database that naturally does not match the Rails conventions, but this has not been a serious problem thanks to rails flexibility. The problem I just ran into is that my "LineItems" table links back to the "Products" table using a modified foreign key. For example, the ProductID in the LineItem table as a "LI-" prefixed to the productID. So they link together as follows: LineItem (ProductID) Product (ID) IN-123456 -> 123456 IN-...

New Model Object from Existing Model Object
Hey Guys, need a hand again.... Lets say I have an Order... and an Order has Order Lines and Order_Lines have Items... I want to create a New Order, which would have New Order Lines with the same Items... Is there a fast / easy way to do this, w/o having to create a new order, loop through all the order lines, and create them associating them with the Items? Any help would be great, thanks --

Saving one-many associations (elegant solution please)
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
