# This cop looks for `attribute` class methods that specify a `:default` option
# and pass it a method without a block.
#
# @example
# # bad
# class User < ApplicationRecord
# attribute :confirmed_at, :datetime, default: Time.zone.now
# end
#
# # good
# class User < ActiveRecord::Base
# attribute :confirmed_at, :datetime, default: -> { Time.zone.now }
# end
