findOne子文檔中貓鼬

Question

我試圖對一個子文檔中貓鼬一findOne查詢，但我並沒有多少運氣...

我的模式是這樣的：

var Team = mongoose.Schema({ 
    teamName:  String, 
    teamURL:  String, 
    teamMembers: [{username: String, password: String, email: String, dateCreated: Date}], 
}); 

var Team = db.model('Team', Team); 

我需要簡單地找到我使用此查詢的文檔中的用戶電子郵件

Team.findOne({'teamMembers.username': 'Bioshox'}, {'teamMembers.$': 1}, function (err, team) { 
    if (team) { 
     console.log(team[1].email); 
    } 
}); 

任何幫助，將不勝感激！

Answer 1

你錯過了teamMembers水平的對象，所以你的代碼需要改變的東西是這樣的：

Team.findOne({'teamMembers.username': 'Bioshox'}, {'teamMembers.$': 1}, 
    function (err, team) { 
     if (team) { 
      console.log(team.teamMembers[0].email); 
     } 
    } 
);
