[Rails] cloud9でのデバッグ方法

Posted at

#結論

処理を止めたい場所で"debugger"と打ち込む

#例

  def create
    @voice = Voice.new
    @voice.user = current_user
    @voice.voice = params[:voice][:voice]
    
  debugger

    if @voice.save
      redirect_to @voice, notice: 'Voice was successfully created.'
    else
      render :new
    end
  end

この状態でプレビュー画面にて処理を実行。(この場合だとcreateの処理を実行)

#すると

プレビュー画面が停止し、debuggerが起動される。

矢印の部分に変数などを入力することで、処理を止めた時点での変数の値を確認することができる。
