blank?

blank?()

public

An object is blank if it’s false, empty, or a whitespace string. For example, “”, “ ”, nil, [], and {} are blank.

This simplifies:

if !address.nil? && !address.empty?

…to:

if !address.blank?

# File activesupport/lib/active_support/core_ext/object/blank.rb, line 12
  def blank?
    respond_to?(:empty?) ? empty? : !self
  end
