Rails 3 Ordering Bug Demo

This bug occurs when you have a "child" model (one that belongs_to another model) with an order scope on it and you try to set a where condition.

So for the following models:

class Person < ActiveRecord::Base
  has_many :items

class Item < ActiveRecord::Base
  belongs_to :person
  default_scope order(:ordinal)

With the following calls:

Person.includes(:items).where(:name => 'John')
# or
Person.includes(:items).find_by_name 'John'

The items loaded are ordered by the ordinal on each Item.

If you introduce a period into the name, though (e.g. "John.Smith"), the order scope is ignored.

To see this in action...

$ git clone git://
$ cd bug-demo
$ rake db:create db:migrate db:seed
$ rails s

And then fire up http://localhost:3000/ and see for yourself.

Something went wrong with that request. Please try again.
