使用表单访问/设置嵌套值

Question

我的数据库中有 30k+ 个具有这种结构的文档：

{
  ...,
  "hours" : {
    "holiday" : {
      "New Years" : "Call",
      "Easter" : "Closed",
      "Memorial Day" : "Standard",
      "Independence Day" : "Standard",
      "Labor Day" : "Standard",
      "Thanksgiving" : "Closed",
      "Day After Thanksgiving" : "Call",
      "Christmas Eve" : "Call",
      "Christmas" : "Closed",
      "New Years Eve" : "Call"
    },
    "standard" : {
      "mon" : [{
        "open" : "8:00 am",
        "close" : "11:00 pm"
      }],
      "tue" : [{
        "open" : "8:00 am",
        "close" : "11:00 pm"
      }],
      "wed" : [{
        "open" : "8:00 am",
        "close" : "11:00 pm"
      }],
      "thu" : [{
        "open" : "8:00 am",
        "close" : "11:00 pm"
      }],
      "fri" : [{
        "open" : "8:00 am",
        "close" : "11:00 pm"
      }],
      "sat" : [{
        "open" : "8:00 am",
        "close" : "11:00 pm"
      }],
      "sun" : [{
        "open" : "8:00 am",
        "close" : "10:00 pm"
      }]
    }
  },
  ...
}

我正在从一个 php 驱动的站点进行完全重写。我一直在绞尽脑汁，绝对想不出一种方法来制作一个允许我正确设置 business.hours["standard"]["mon"] 的表单字段。该网站每天提供多个打开/关闭条目，用于午餐关闭的企业等。该属性将设置为 [{"open" : "8:00 am", "close" : "12:00 pm}, {"open" : "1:00 pm", "close" : "5:00 pm}] 在这种情况下。我想为每个条目提供两个选择框，一个用于开放时间，一个用于关闭时间。

这是我的模型。包括一些我试图弄清楚如何绑定到我的表单中的 getter/setter...不成功。

class Business

  after_initialize do |b|
    b.hours = Hash.new unless b.hours
    b.hours["holiday_hours"] = {"New Years" => "Call",
                                "Easter" => "Call",
                                "Memorial Day" => "Call",

                                "New Years Eve" => "Call"} unless b.hours["holiday_hours"]

    b.hours["standard_hours"] = Hash.new unless b.hours["standard_hours"]
  end

  def holiday_hours
    hours["holiday_hours"] if hours["holiday_hours"]
  end

  def holiday_hours=(hours)
    self.hours["holiday_hours"] = hours if hours.present?
  end

  def holiday_hours_for(holiday)
    hours["holiday_hours"][holiday.to_s] if hours["holiday_hours"][holiday.to_s]
  end

  def update_holiday_hours_for(holiday, hours_text)
    self.hours = Hash.new unless hours
    self.hours["holiday_hours"] = Hash.new unless hours["holiday_hours"]
    self.hours["holiday_hours"][holiday.to_s] = hours_text.to_s
  end

  def standard_hours
    hours["standard_hours"] if hours["standard_hours"]
  end

  def standard_hours_for(day)
    hours["standard_hours"][day.to_s] if hours["standard_hours"][day.to_s]
  end
end

谢谢！

我想出了一个办法，虽然我不能 100% 确定这是正确的方法。

attr_accessible :ad, :address, :city, :claimed, :coupons, :created_at, :updated_at, :extra_services, :hours,
