Acts as Sweepable

gem install acts_as_sweepable

and in your Gemfile:

gem 'acts_as_sweepable'

Adds a class method called sweep to ActiveRecord - used to remove old elements.

# Will remove elements that weren't updated from at least 10 days
MyClass.sweep(:time => '10d')

# Will remove elements that weren't updated from at least 10 hours
MyClass.sweep(:time => '10h')

# Will remove elements that weren't updated from at least 10 minutes
MyClass.sweep(:time => '10m')

Params accepted by this method:

• time - d(days),h(hours), m(minutes)
• conditions - additional SQL conditions (like WHERE)
• columns - (default :updated_at) - which columns should it consider when removing
• method - (default: :destroy_all) - which method should it use to destroy objects
• format - (default: :db) - should it use to_s(:db) or to_i

You can also yield a block of code - it will be performed on every object that should be deleted:

MyClass.sweep(:time => '10d') do |el|
    el.do_smhtng
end

• Fork the project.
• Make your feature addition or bug fix.
• Add tests for it. This is important so I don't break it in a future version unintentionally.
• Commit, do not mess with Rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
• Send me a pull request. Bonus points for topic branches.
