從cloudant json獲取匹配部分

我正在爲我的spring應用程序使用cloudantDB作爲數據庫。從cloudant json獲取匹配部分

，我試圖做的事情是：

檢查是否有文檔中的時隙和話題
如果填寫一個話題：
檢查已提交該主題的userId並返回該用戶的所有項目。

    }, 
 
    "defaultTwitterText": "Hallo", 
 
    "twitterUrl": "https://twitter.com/intent/tweet?button_hashtag=confTag&text=Hallo" 
 
}

到目前爲止，我有這樣的：

function(doc) { 
{ if (doc.type === 'conference') { 
    if(doc.timeslots.size !==0){ 
      emit(null, doc); 
     } 
    } 
    } 
}

謝謝！

我想你可能想是這樣的：

function (doc) { 
    if (doc.type == 'conference'){ 
    if (doc.timeslots){ 
      for (var i in doc.timeslots) { 
       if(doc.timeslots[i].topic){ 
        emit(doc.timeslots[i].topic.speakerId, doc.timeslots[i]) 
       } 
      }; 
     } 
    } 
}

也許會讓的key:speaker, value: topic object一個視圖，然後你可以?key=speaker查詢到看到所有的音箱的主題對象的列表。
