A good way to validate whether an object is Truthy or Falsey in Ruby or Rails apps is to use the ActiveSupport present? & blank? methods.

active_support_tips_01.rb

# The Rails ActiveSupport core extensions provide additional
# functionality to any Rails or Ruby application.
require "active_support"

# ActiveSupport#blank?
nil.blank?  # => true
false.blank? # => true
{}.blank? # => true
[].blank? # => true
"".blank?  # => true
" ".blank? # => true

# ActiveSupport#present?
nil.present?  # => false
false.present? # => false
{}.present? # => false
[].present? # => false
"".present?  # => false
" ".present? # => false
