Ruby String to Boolean

string_to_bool.rb

module StringToBooleanRefinementsService
  refine String do
    def to_bool
      return true  if self == true   || self =~ /(true|t|yes|y|1)$/i
      return false if self == false  || self.blank? || self =~ /(false|f|no|n|0)$/i

      raise ArgumentError, "invalid value for Boolean: \"#{self}\""
    end

    alias_method :to_b, :to_bool
  end
end

# Include to your class where change wanted.
    
 class StringExample
   using StringToBooleanRefinementsService
 end

In Rails same result can be achieved by ActiveModel::Type::Boolean.new.cast('t')
