[英]Rails filter by date with MetaSearch
我有一些在視圖中顯示的記錄。 它們具有start_date
和end_date
。 訪問視圖時,默認情況下,我只希望它顯示誰的日期未過期的記錄。 過期被定義為:
然后,我希望有一個復選框顯示所有記錄,包括已過期的記錄。
我該如何處理?
在控制器操作中,您希望將其放置在某處:
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])
您還可以繞過所有搜索內容,而僅使用如下范圍:
@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)
