Truthiness is...

...knowing that one line can make a difference.

Truthiness

This is a simple gem with a simple purpose. I love Ruby. One of the biggest reasons why I love Ruby so much is because of its readability. Unfortunately, I'd been forever typing stuff like this:

validates_inclusion_of :loves_long_walks_on_the_beach, :in => [true, false]

Is this horrible? Hell no. Do I want to make it better? Hell yes.

What I really wanted to type was this:

validates_truthiness_of :loves_long_walks_on_the_beach

See 'Aliases' at the bottom if you'd rather have a more unambiguous validation title. :)

Installation

gem install validates_truthiness

Usage

You can either use the Rails 2-style to chain multiple columns together: validates_truthiness_of :opting_out_of_newsletters, :consents_to_strip_search

Or the Rails 3-style: validates :works_hard_for_the_money, truthiness => true

If you'd like a specific message, say "Yes" or "No" instead of "True" or "False", just pass it as a :message option:

validates :believes_they_may_be_a_cylon,
          :truthiness => {:message => "must be either a 'Yes' or a fraking 'No'"}

Also, don't forget you can :allow_nil in case you need the triumvirate of: true, false and nothing.

I18n

Due to this being wired up through ActiveModel, internationalization is free, just add the proper keys to your .yml files.

No Stone Unturned

Just to make sure this was the ULTIMATE boolean validation gem, although I believe use cases for these are slim to none:

Validating Truth

validates_verity_of
validates_truth_of

Validating Falsity

validates_falsity_of
validates_falsehood_of

Aliases

In case some of you aren't fond of the ambiguity of "truthiness" I've also aliased validates_truthiness_of to validates_booleanship_of
