I just updated to 2.1 and created a new, empty project. According to the docs I've seen, including:
http://ryandaigle.com/articles/2008/4/1/what-s-new-in-edge-rails-partial-updates
The file config/initializers/new_rails_defaults.rb has the default setting for partial updates and just needs to be edited: "Note: There’s currently a config/initializers/new_rails_defaults.rb file that has this setting, so edit that file if you have it."
However, in the new_rails_defaults.rb file in my new empty project does not have that setting in it (ActiveRecord::Base.partial_updates = ...)
Yeah, I can add it, but I thought it should already be in there?
Thanks, jt
