Add union_hack.rb to your project, for example at lib folder and ensure you're loading it on your application.rb file:

    # You'll need to add something like that
    config.autoload_paths += %W(#{config.root}/lib)

Then extend your favourite model with the module and you'll be able to do unions with unique records, sorted by any fields and limited in number of records (see my_timeline_method):

    class Profile < ActiveRecord::Base
      extend UnionHack

Say I have 5 files: (file1, file2, ... file5).

All have been commited.

Say now all 5 files have been changed.

When you issue git status, all 5 files should be shown as (red) unstaged status.

Say I am happy with the changes in file1 to file4, but not file5 (i.e. I'd like to revert file5 to the last committed stage).
