Rails 4.2 アプリで Ahoy gem を使用しています。propertiesAhoy Events は、多数のテキスト属性とクエリしたいデータを含む属性を持つイベントを保存します。たとえば、Rails コンソールから返された最後のイベントは次のとおりです。
>> Ahoy::Event.last
Ahoy::Event Load (3.8ms) SELECT "ahoy_events".* FROM "ahoy_events" ORDER BY "ahoy_events"."id" DESC LIMIT 1
=> #<Ahoy::Event id: "fffff17f-44e6-41d7-9c32-fa895338f54e", visit_id: "6b05b1ca-3863-46da-9c48-a3ab5fa4a9ee", user_id: 1, name: "$click", properties: {"tag"=>"a", "page"=>"/conversations/2", "text"=>"View", "href"=>"/conversations/2"}, time: "2015-08-23 13:25:51">
properties['text'] = 'View' であるすべてのイベントを取得するにはどうすればよいですか?
私が試してみましたAhoy::Event.where(:properties['text'] => 'View').count
これは次を返します: ```
Ahoy::Event.where(:properties['text'] => 'View').count NoMethodError:

ハッシュ属性のクエリをオンラインで調べましたが、成功しませんでした。どんなガイダンスも大歓迎です。
