ユーザーにタイムスケールで検索するオプションを提供しようとしています。次のようなドロップダウンメニューにオプションを表示するドロップダウンメニューが必要です。
検索: 3 日前、1 週間前、1 か月前、6 か月前、1 年。など。
Railsが3日前にクエリを実行したいことを理解するために使用する必要があることは理解していDateTime.now.to_date - 3.daysますが、ユーザーに3日前のオプションをドロップダウンのテキストとして表示させる方法がわかりませんが、クエリDateTime.now.to_date - 3.days
ありがとう
現在、私の検索ビューは次のようになっています。
