Mock with an attributes that has state
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

In my Order model I need a way to merge OrderItems which have the same cost
and same product_id. That I can spec.

How can I create OrderItems that go in a Order?
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

Creating multiple option groups
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

Nested find(:all, :include => ) statements
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.

SOAP for large datasets
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

ActiveRecord saving madness?
Hello,
First of all, I love RoR. I am studying it, and I am finally "getting
there".
However, I do have a bit of a problem with ActiveRecord''s saving
behaviour.
Imagine to have Orders (id, name) {has_one:invoice} and Invoices (id,
order_id) {belongs_to :order} .
If you type:
invoice = Invoice.new(...whatever...)
an_order.invoice = invoice
if invoice fails to save, you

Question about using DISTINCT in ActiveRecord find method.
Hi,
Am relatively new to the RoR world. My question is quite simple.
I have a query like such:

o, line_items li, shipment_lines sl, shipments s where o.number=? and
o.id = li.order_id and li.id = sl.line_item_id and sl.shipment_id =

The above query works fine. I wanted to do the same query using

HABTM problem not saving all associations

I have an Order object that has and belongs to many Products and has

Hi..Guys new plugin again
Hi..
Guys new plugin again
Foreign Key Associations is a plugin that automatically creates
associations based on foreign-keys. The associations are created at
runtime-ie. as your ActiveRecord models are loaded-so they will always
be up-to-date.
For example, given a foreign-key from a customer_id column in an
orders table to an id column in a customers table, the plugin
creates:
