Overview

This cop looks for ‘attribute` class methods that specify a `:default` option and pass it a method without a block.

Examples:

# 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
