ruby-on-rails - rails : How to make strong parameters easy to read

Question

我的应用程序具有如下强大的参数。

如何使这段代码易于阅读？

这一行有很多属性

我的 Controller

  def create
    @schedule = current_user.schedules.build(schedule_params)
    ...
  end

  ...

  def schedule_params
    params.require(:schedule).permit(:title, :departure_date, rooms_attributes: [:id, :_destroy, :room, :room_address, :day, :ccy, :amount, events_attributes: [:id, :_destroy, :start_at, :end_at, :title, :detail, :category, :ccy, :amount, amounts_attributes: [:id, :_destroy, :ccy, :amount]]])
  end

如果您能给我任何建议，我们将不胜感激。

Answer 1

除了字符串，ruby 主要忽略空格。这使得可以轻松地将一行代码分成多个部分。您可以利用它来使您的参数更易于阅读:

def schedule_params
  params.require(:schedule).permit(
    :title, :departure_date,
    rooms_attributes: [
      :id, :_destroy, :room, :room_address, :day, :ccy, :amount,
      events_attributes: [
        :id, :_destroy, :start_at, :end_at, 
        :title, :detail, :category, :ccy, :amount, 
        amounts_attributes: [:id, :_destroy, :ccy, :amount]
      ]
    ])
end
