Cold Shoulder

Rails validation gem which ensures no contact information can be passed into a field. Looks for Twitter handles, email addresses, and phone numbers

Rails 4:

gem 'cold_shoulder'

Rails 3: Same as above, it should work with major versions of Rails 3, nothing too crazy going on in here.

Usage Example

class Message < ActiveRecord::Base
  validates :body, cold_shoulder: true
end

Validation Options

class Message < ActiveRecord::Base
  validates :body, cold_shoulder: {
    ignore_twitter: true, # Don't add errors when twitter handles are detected
    ignore_email: true,   # Don't add errors email addresses are detected
    ignore_phone: true,   # Don't add errors when phones are detected
    ignore_link: true,    # Don't add errors when links are detected
    remove_links: true,   # Strip any found links from the actual saved value, setting to true will ignore links
    ignore_number_words: true # Don't count 'zero, one, two' as '0, 1, 2' etc this is used to catch phone numbers as words
    message: 'Use this to override all the specific messages'
  }
end

What can it catch?

Here are some examples, straight out of the Rspec tests!

Email addresses

[email protected]
dustin.hoffman at breefield.com
dustin.hoffman [ a t ] breefield.com

Phone numbers

208 871 2069
(208)8712069
+1 (208)871-2069
2 0 8 8 7 1 2 0 6 9
2\n0\n8\n8\n7 lol Rob Ford \n1\n2\n0\n6\n9
two oh eight 8 7 one 2 oh six 9
two zero eight eight seven one two oh six nine

It won't missfire and catch:

$1,000,000,000

Twitter handles

@valid_username

Override validation messages

In config/locals/en.yml

Contributing

1. Fork the project
2. Make your feature addition or bug fix
3. Add tests for it. This is important so I don't break it in a future version unintentionally.

• cold_shoulder uses rspec, all tests are in spec/cold_shoulder_spec.rb

4. 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)
5. Send us a pull request
