NameError: uninitialized constant Arel::Relation

[sunaku]

Hello,

I'm using Arel from Git (since my app needs patches that have been merged into master) with Rails 3.2.8 and I'm getting a NameError: uninitialized constant Arel::Relation error when running my functional tests. Here's my setup:

$ rails -v
Rails 3.2.8
$ ruby -v
ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-linux]
$ bundle list | grep arel
  * arel (3.0.2.20120819075748 de7e7c8)

Currently, I'm using this hack in my test_helper to work around the issue:

# XXX: this fixes NameError: uninitialized constant Arel::Relation
# http://intertwingly.net/blog/2012/03/28/Keeping-it-on-the-Rails
module Arel::Relation; end

Thanks for your consideration.

BTW @tenderlove is this incompatibilty with Rails 3.2.8 the reason why a new Arel gem release hasn't been made? Could we move the incompatible changes out of master (to a different branch) and then release the other (compatible) patches?

The master branch should be used with edge rails. Please only use the release gems. If there is something on master that needs to be backported to stable and released, please file a new ticket. Thanks.
