    def update
      if current_user.valid_password? params[:user][:current_password]
        if current_user.update(user_params)
          flas
    
    def show; end

    def update
      if current_user.valid_password? params[:user][:current_password]
        if current_user.update(user_params)
          flash[:success] = 'Settings successfully saved.'
          redirect_to settings_account_path
        else
          render :show
