Faker

This gem is a port of Perl's Data::Faker library that generates fake data.

It comes in very handy for taking screenshots (taking screenshots for my project, Catch the Best was the original impetus for the creation of this gem), having real-looking test data, and having your database populated with more than one or two records while you're doing development.

Installing

gem install faker

Customization

Since you may want to make addresses and other types of data look different depending on where in the world you are (US postal codes vs. UK postal codes, for example), Faker uses the I18n gem to store strings (like state names) and formats (US postal codes are NNNNN while UK postal codes are AAN NAA), allowing you to get different formats by switching locales. Just set Faker::Config.locale to the locale you want, and Faker will take care of the rest.

If your locale doesn't already exist, create it in the \lib\locales\ directory and you can then override or add elements to suit

en-au-ocker:
  faker:
    name:
      # Existing faker field, new data
      first_name: [Charlotte, Ava, Chloe, Emily]

      # New faker fields
      ocker_first_name: [Bazza, Bluey, Davo, Johno, Shano, Shazza]
      region: [South East Queensland, Wide Bay Burnett, Margaret River, Port Pirie, Gippsland, Elizabeth, Barossa]
