簡単にレエイルズのfilterの確認がしたい

test.rb

require "text-table"

module AbstractController
  module Callbacks
    def process_action(*args)
      run_callbacks(:process_action) do
        super
      end

      table = Text::Table.new
      table.head = ["callback_name", "kind"]
      _process_action_callbacks.each do |v|
        _if = self.instance_eval(v.instance_variable_get(:@if).join("&&"))
        if !_if.nil? && !_if
          next
        end
        table.rows << [v.filter, v.instance_variable_get(:@kind)]
      end
      puts table.to_s
    end
