我有一组 7 个下拉输入，允许管理员说出他们在给定日期是营业还是关闭。我希望将其更改为 7 个打开/关闭开关（大概是样式复选框？）但不知道该怎么做！

以下是我目前拥有的相关代码位（在任何更改之前）：

应用程序/视图/后端/inventory_pool/edit.html.haml

- content_for :title, @inventory_pool
  = form_for [:backend, @inventory_pool], html: {name: "form"} do |f|

    .content
      - if is_admin?
        %a.button{:href => root_path}= _("Cancel")
      %button.button{:type => :submit}= _("Save %s") % _("Inventory Pool")

      %section
        %h2= _("Basic Information")
        .inner
          .field.text
            .key
              %h3= "#{_("Print Contracts")}"
              %p.description
            .value
              .input
                %input{type: "checkbox", name: "inventory_pool[print_contracts]", checked: @inventory_pool.print_contracts}


      %section#workdays
        %h2= _("Workdays")
        .inner
          - [1,2,3,4,5,6,0].each do |i|
            .field.text
              .key
                %h3= "#{I18n.t('date.day_names')[i]}"
              .value
                .input
                  %select{:name => "store[workday_attributes][workdays][]"}
                    %option{:label => _("Open"), :value => Workday::WORKDAYS[i]}= _("Open")
                    %option{:label => _("Closed"), :value => "", :selected => @store.workday.closed_days.include?(i) ? true : nil}= _("Closed")

应用程序/模型/workday.rb

class Workday < ActiveRecord::Base

  belongs_to :inventory_pool

  WORKDAYS = ["sunday", "monday", "tuesday", "wednesday", "thursday", "friday", "saturday"]

  def is_open_on?(date)

    return false if date.nil?

    case date.wday
    when 1 return monday
    when 2 return tuesday
    when 3 return wednesday
    when 4 return thursday
    when 5 return friday
    when 6 return saturday
    when 0 return sunday
    else
      return false #Should not be reached
    end
  end

  def closed_days
    days = []
    days << 0 unless sunday
    days << 1 unless monday
    days << 2 unless tuesday
    days << 3 unless wednesday
    days << 4 unless thursday
    days << 5 unless friday
    days << 6 unless saturday
    days
  end

  def workdays=(wdays)
    WORKDAYS.each {|workday| write_attribute(workday, wdays.include?(workday) ? true : false)}
  end
end

在app/controllers/backend/inventory_pools_controller我有这个（删节）：

  def update
    @inventory_pool ||= InventoryPool.find(params[:id])
    process_params params[:inventory_pool]
  end

  def process_params ip
    ip[:print_contracts] ||= "false" # unchecked checkboxes are *not* being sent
    ip[:workday_attributes][:workdays].delete "" if ip[:workday_attributes]
  end

这可能是一个相当大的变化，但我发现最好的方法与Ryan Bates 的 Railscast on using a bitmask非常相似。本教程很棒并且设置起来相对较快，并且应该很容易地从用户角色（在教程中使用）映射到Workday应用程序中的一周中的几天。

OK. In the haml, I had to replace:

            .input
              %select{:name => "store[workday_attributes][workdays][]"}
                %option{:label => _("Open"), :value => Workday::WORKDAYS[i]}= _("Open")
                %option{:label => _("Closed"), :value => "", :selected => @store.workday.closed_days.include?(i) ? true : nil}= _("Closed")

With:

        = check_box_tag "inventory_pool[workday_attributes][workdays][]", Workday::WORKDAYS[i], @inventory_pool.workday.closed_days.include?(i) ? nil : true
