rescue_from没有捕获错误

Question

class MyController < ApplicationController
  before_action :set_data, only: [:show, :edit, :update, :destroy]
  rescue_from ActiveRecord::RecordNotFound, with: :invalid_data
  respond_to :html

  def show
   respond_with(@item)
  end

  private

  def set_data
    @item = Item.find params[:id]
  end


  def invalid_data
    logger.log "Error, id: #{params[:id]}"
    redirect_to some_url, error: 'Error123'
  end

end

Still, when I go to my/123 or my/123fdsfds or my/fdsfds , I get a standard "error" screen:

ArgumentError in MyController#show
comparison of String with 0 failed

    logger.log "Error, id: #{params[:id]}"
    redirect_to some_url, error: 'Error123'
  end
end 

and I don't get redirected. How come?

我原来，looger.log本身引起了错误，应该是：

logger.log Logger::ERROR, "Error, id: #{params[:id]}"
