node.js - Mongoose 没有保存数据没有错误

Question

我有这个代码

      User.findOne({ email: req.body.email }, function(err, user) {
        if (user) {
          return res.status(400).json([{ msg: 'The email address you have entered is already associated with another account.' }]);
        }
        user = new User({
          name: req.body.name,
          email: req.body.email,
          password: req.body.password,
          mobile: req.body.mobile
        });
        user.save(function(err) {
          res.json({ token: generateToken(user), user: user });
        });
      });

我尝试用 postman 发送请求，我确实收到了用户对象的回复，这意味着保存函数中没有错误

{
  "token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpc3MiOiJleGNlcHRpb25zLnNnIiwic3ViIjoiNTc5NWQ0NzQxYmEzZWQwODE1ZTgzY2NmIiwiaWF0IjoxNDY5NDM3MDQ0LCJleHAiOjE0NzAwNDE4NDR9.2otkcPkJgsXvR8QOHAojDJ5YCxR7Uc2E4ApS77T55F8",
  "user": {
    "__v": 0,
    "created_at": "2016-07-25T08:57:24.612Z",
    "updated_at": "2016-07-25T08:57:24.612Z",
    "name": "Test",
    "email": "Test@hotmail.com",
    "password": "$2a$10$3UmABiDPeo6iHZ.DFbwOO.1ANpUWQmwr86bYbTmRuFedsbDcE0bbC",
    "mobile": 12345,
    "_id": "5795d4741ba3ed0815e83ccf"
  }
}

但是我的数据库中没有这个条目。我用 Robomongo 检查了我的数据库，我确定没有数据。我错过了什么？

这与 OP 的具体情况无关，但对于在修改对象的 Mixed 属性后尝试保存失败的其他人，您必须调用 markModified(path) 让 Mongoose 知道属性已经改变。

person.anything = { x: [3, 4, { y: "changed" }] }; // anything is 'Mixed' in the schema
person.markModified('anything');
person.save(); // anything will now get saved

查看 Mongoose docs here 的“混合”部分
