Question

我是Mongodb和Mongoose的新手。我有用户收藏。因此我必须根据电子邮件的用户ID插入或更新。

我使用了以下查询

 var query={"userid":req.body.user_id, 
        "email":req.body.email,         
         "firstname":req.body.first_name,
         "lastname":req.body.last_name,
         "mobilenumber":req.body.phone_number};

db.update(query, {$set: {userid: req.body.user_id }}, {upsert:true},
         function(err,doc){

            if(err) {
                response = {"MethodName":"RegisterUser","isFault" : true,"ResponseData" : "Error adding data"};
            } 
            else {
                response = {"MethodName":"RegisterUser","isFault" : false,"ResponseData" : "User Registration completed successfully"};
            }
    }); // Added this here. Check your code if it is missing.

但这会引发无效的回调参数错误。

当我删除{upsert:true}时，我没有收到任何错误。但是数据没有更新。当我添加{upsert:true}时，我收到以下错误，我得到的错误。

Error: Invalid callback() argument.

请帮忙。
