プログラミングの備忘録

(pry) output error: #<ActionController::UnfilteredParameters: unable to convert unpermitted parameters to hash> と怒られた

rails 5. 1.4 ruby 2.4.1p111 (2017-03-22 revision 58053) [x86_64-darwin16] の環境でform_forを利用して開発している時に見かけたエラー。

controllerの処理の中でbinding.pryを実行し、’params’と確認すると、

と、こんなエラーが吐かれてしまった。。。。。。。。。。 なぜだ。。。。。rails4系では問題なくみれていたのだが、、、、

解決はしていないが、対処方法としては rails server のパラメータを頑張って読んで、そこから必要なデータを読み解くしかない?w

あとは rails dashboardとかを利用して出力結果をパースするか。

ちなみにrails dashboardを使うとこんな感じになる

  authenticity_token : Aevh******************sAoM/AZRL*********************GHAW06V+==
              commit : ????????
             product : Object
     product[detail] : test message
       product[name] : 1039
      product[price] : 50000
     product[status] : excellent
                utf8 : ✓

おそらくrails5系からセキュリティ面の考慮が入りこの仕様になったのだと思うが、、、にしてもめんどくさい。。。。。。。 なにかいい方法はないのだろうか?

追記:デバッグ用のgemのどれかが悪さをしているっぽい。

group :development, :test do
  # Call 'byebug' anywhere in the code to stop execution and get a debugger console
  gem 'byebug', platforms: [:mri, :mingw, :x64_mingw]
  # Adds support for Capybara system testing and selenium driver
  gem 'capybara', '~> 2.13'
  gem 'selenium-webdriver'
  gem 'pry-rails'    # rails cの対話式コンソールがirbの代わりにリッチなpryになる
  # gem 'pry-doc'      # pry中に show-source [method名] でソース内を読める
  # gem 'pry-byebug'   # binding.pryをソースに記載すると、ブレイクポイントとなりデバッグが可能になる
  # gem 'pry-stack_explorer' # pry中にスタックを上がったり下がったり行き来できる

  # gem 'hirb'         # モデルの出力結果を表形式で表示する
  # gem 'hirb-unicode' # hirbの日本語などマルチバイト文字の出力時の出力結果がすれる問題に対応
  # gem 'rails-flog', require: 'flog' # HashとSQLのログを見やすく整形
  gem 'better_errors'     # 開発中のエラー画面をリッチにする
  # gem 'binding_of_caller' # 開発中のエラー画面にさらに変数の値を表示する
  # gem 'awesome_print'     # Rubyオブジェクトに色をつけて表示して見やすくなる
end

もともと利用していた、gemをコメントアウトしたら一応動くようになった。。。。
