Question

当我传递不同的参数时，相同的代码块可以工作，然后却无法工作，这让我有些困惑。

有问题的代码：

exports.profileGet = (req, res) => {
   // console.log(req.user._id)
const id = req.user._id.toString()
console.log(id)

User.find({ username: 'p' }).exec((err, user) => {
  if (err) {
    res.render('profile')
  }
  console.log(user)
})

Photo.find({ userId: id }).exec((err, results) => {
  if (err) {
    res.render('profile')
  }
  console.log(results)
})

}

console.log（id）在console.log中返回此值：

5c89a00e102515541329db1a

哪个是正确的用户ID。

然后User.find在控制台日志中返回此值：

[ { isAdmin: false,
_id: 5c89a00e102515541329db1a,
email: 'p',
username: 'p',
password:
 '$2b$10$CTihm9TXcbyYFEHZU8GruOT61kyBDTj7wFGg4QaQN6bIMpnKv6oiO',
__v: 0 } ]

这是正确的用户，显示.find（）方法有效。

但是照片 .find在console.log中返回此值（即使我给了它适当的参数）：

throw er; // Unhandled 'error' event
  ^

“照片”模型的参数与查询匹配：

const mongoose = require('mongoose');
const Schema = mongoose.Schema;
const photoSchema = new Schema({
    name: { type: String },
    data: { type: Buffer },
    contentType: { type: String },
    userId: { type: String }
 });

module.exports = mongoose.model('photos', photoSchema);

如您在图像中所见，数据在mongo中，因此它应该找到文件...

Photo data in mongo database

我完全不知所措！

非常感谢您的帮助。

谢谢：）
