StripAttributes

StripAttributes is a Rails plugin that automatically strips all ActiveRecord model attributes of leading and trailing whitespace before validation. If the attribute is blank, it strips the value to nil.

It works by adding a before_validation hook to the record. By default, all attributes are stripped of whitespace, but :only and :except options can be used to limit which attributes are stripped. Both options accept a single attribute (:only => :field) or arrays of attributes (:except =>

= Examples class DrunkPokerPlayer < ActiveRecord::Base strip_attributes! end class SoberPokerPlayer < ActiveRecord::Base strip_attributes! :except => :boxers end class ConservativePokerPlayer < ActiveRecord::Base strip_attributes! :only => [:shoe, :sock, :glove] end

=== Installation

Option 1. Use the standard Rails plugin install (assuming Rails 2.1).

./script/plugin install git://github.com/rmm5t/strip_attributes.git

Option 2. Use git submodules

git submodule add git://github.com/rmm5t/strip_attributes.git vendor/plugins/strip_attributes

Option 3. Use braid[http://github.com/evilchelu/braid/tree/master] (assuming you’re using git)

braid add --rails_plugin git://github.com/rmm5t/strip_attributes.git
git merge braid/track

=== Other

If you want to use this outside of Rails, extend StripAttributes in your ActiveRecord model after putting strip_attributes in your $LOAD_PATH:

require 'strip_attributes'
class SomeModel < ActiveRecord::Base
  extend StripAttributes
  strip_attributes!
end

=== Support

The StripAttributes homepage is http://stripattributes.rubyforge.org. You can find the StripAttributes RubyForge progject page at: http://rubyforge.org/projects/stripattributes

StripAttributes source is hosted on GitHub[http://github.com/]: http://github.com/rmm5t/strip_attributes

Feel free to submit suggestions or feature requests. If you send a patch, remember to update the corresponding unit tests. In fact, I prefer new features to be submitted in the form of new unit tests.

=== Credits

The idea was triggered by the information at http://wiki.rubyonrails.org/rails/pages/HowToStripWhitespaceFromModelFields but was modified from the original to include more idiomatic ruby and rails support.
