我有一些我在视图中显示的记录。他们有start_dateend_date。当我访问视图时,默认情况下我只希望它显示日期未过期的记录。过期被定义为:

  • 结束日期和开始日期 <= 现在,并且
  • 结束日期晚于开始日期

然后我想要一个复选框,显示所有记录,包括已过期的记录。

我该如何处理?

在您的控制器操作中,您希望在某处拥有它:

params[:search] ||= {} # make sure this is instantiated

# filter to show the expired records
if params[:include_expired] # check if the checkbox is checked
  params[:search][:end_date_lte] = Date.today # end_date <= Now
  params[:search][:start_date_lte] = Date.today # end_date <= Now
end

@records = params[:include_expired] ? RecordClass.where("end_date > start_date").search(params[:search]) : RecordClass.search(params[:search])

您还可以绕过所有搜索内容,只使用这样的范围:

@records = params[:include_expired] ? RecordClass.expired : RecordClass.all # or whatever logic you need

# scope in the RecordClass
scope :expired, where("end_date > start_date AND end_date <= ?", Date.today)
