findOne子文档中猫鼬

Question

我试图对一个子文档中猫鼬一findOne查询，但我并没有多少运气...

我的模式是这样的：

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

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

我需要简单地找到我使用此查询的文档中的用户电子邮件

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

任何帮助，将不胜感激！

Answer 1

你错过了teamMembers水平的对象，所以你的代码需要改变的东西是这样的：

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