node.js - Mongoose 保存在 if 语句的第二部分不起作用

Question

我的 Node/Express API 中有一个函数，我首先检查“联系人”集合中是否存在“联系人”。如果是这样，我会进行更新。如果查询中的电子邮件不存在，那么我会创建一个新的。

如果联系人存在，则 contact.save() 有效。但如果联系人不存在，contact.save() 会生成一条错误消息，指出“contact.save() 不是函数。

我不明白我做错了什么。希望那里的人能够很容易地看到它并给我一些建议。

这是代码:

  // SEARCH IF CONTACT EXISTS IN SENDERS CONTACTS -  BY OWNERID AND EMAIL IN EMAILS
  Contact.findOne({'owner_id': req.body.owner_id, 'emails.email_address':req.body.invited_email}, function(err, contact){
    if(err)
      console.log('Error in looking for contact.');


    // IF A CONTACT EXISTS ---
    if(contact){

      console.log('--> CONTACT FOUND');

          // SET CONTACT SHARED INFORMATION
          contact.shared.invite_id = req.body.invited_first_name + req.body.invited_last_name + req.body.owner_id;
          contact.shared.profile_id = req.body.profile_id;
          contact.shared.first_name = req.body.first_name;
          contact.shared.company = req.body.company;
          contact.shared.title = req.body.title;
          contact.shared.last_name = req.body.last_name;
          contact.shared.initial = req.body.initial;
          contact.shared.linkedin = req.body.linkedin;
          contact.shared.google = req.body.google;
          contact.shared.facebook = req.body.facebook;
          contact.shared.pinterest = req.body.pinterest;
          contact.shared.twitter = req.body.twitter;
          contact.shared.emails = req.body.emails;
          contact.shared.phones = req.body.phones;
          contact.shared.addresses = req.body.addresses;
          contact.shared.link = req.body.invited_first_name + req.body.invited_last_name + req.body.owner_id;


          // ADD TO ALERT INFORMING SENDER THAT HE/SHE SHARED INFO
          alerts.genShare(req.body.owner_id, req.body.invited_first_name, req.body.invited_last_name, req.body.invited_email);

          // SAVE CONTACT INFORMATION
          contact.save(function(err){
            if(err)
              res.send(err);
            res.json(contact);
          });

Answer 1

您已使用对象重写了您的联系人:

contact = {
          emails: email,
          owner_id:req.body.owner_id,
          profile_id:req.body.profile_id,
          first_name: req.body.invited_first_name,
          last_name : req.body.invited_last_name,
          shared:share
      };

然后您尝试调用此处不存在的函数 save。
