具有多個參數的CouchDB視圖

Question

我有一個具有id列和ts列的數據庫。 我需要能夠傳遞ID以及開始時間和結束時間來檢索指定時間段內的所有值。 我可以使用視圖執行此操作，還是需要視圖返回與ID匹配的所有值？ 我擔心的是，我將返回並解析比我真正關心的更多的數據。 這是我當前視圖中數據庫的格式，該格式僅返回與id匹配的所有內容...

...我當前的查詢是http://localhost:5984/hist/_design/hist/_view/byId?key=%22A-Meter-KW%22&descending=true 。 我也想傳遞開始和結束時間，例如http://localhost:5984/hist/_design/hist/_view/byId?key=%22A-Meter-KW%22&descending=true&start=1437963300000&end=1437966000000但無法弄清楚該如何做。

Answer 1

編輯：為了使Couch匹配您的查詢，所有數據（例如：A-Meter-KW和日期）必須在視圖發出的key中 。 因此，我認為您可能會執行以下操作：

發出（[鍵，年，月，日]，doc._id）

然后，您可以使用參數startkey和endkey來正確過濾結果。

參考： http : //guide.couchdb.org/draft/views.html#many

側面考慮：我不會在文檔中使用“ id”屬性，因為它很容易與“ _id”（強制性）混淆。
