Mongoose多个$推送到多个阵列

Question

我正在尝试更新Mongodb中的多个数据库条目:

User.findByIdAndUpdate(req.user._id,
    {$push: {people_seen: person_id}},
    {$push: {people_liked: person_id}},
    function(err, usr){
        console.log(req.user);
        res.json({success: true});
});

但是,只是people_seen得到了保存.

Answer 1

您正在$push多次使用该运算符.第二个参数findByIdAndUpdate是选项文档.正确$push的语法是:

{ $push: { <field1>: <value1>, ... } }

并且查询中的正确查询是:

User.findByIdAndUpdate(req.user._id,
    { $push: { people_seen: person_id, people_liked: person_id }},
    function(err, usr){
        console.log(req.user);
        res.json({ success: true });
});
