Node.js：用Mongoose更新文档

我正尝试在受邀用户注册时更新邀请。 邀请有一个auth属性，它是一个嵌套的对象，它本身有一个“使用”键的属性。 我只是试图显式声明的值为真，并保存，使用asynchronous/等待。 但它不是更新。 有一个更好的方法吗？

我的function：

exports.invitedSignup = async (req, res, next) => { const { firstName, lastName, company, password, email, companyCode, token } = req.body; console.log(email); try { const user = await User.findOne({ email }); const invitation = await Invitation.findOne({ email }).sort({ field: 'asc', _id: -1 }).limit(1); if (user) { return res.status(422).send({ error: "User is already registered" }); }; if (!invitation) { return res.status(422).send({ error: "No invitation on record" }); }; if (token !== invitation.auth.token) { return res.status(422).send({ error: "Something has gone wrong, please sign up again" }); } try { invitation.auth.used = true; const updateInvitation = await invitation.save(); console.log("authorization: " + invitation.auth.used); } catch (e) { return next(e); } try { const saveUser = new User({ firstName: firstName, lastName: lastName, email: req.body.email, password: password, company: company, companyCode: companyCode, role: 1, auth: { used: true } }); const newUser = await saveUser.save(); const { email, firstname, lastname } = newUser; res.json({ token: tokenForUser(newUser), email, firstName, lastName }); } catch (e) { return next(e); } } catch (e) { return next(e); } }; 

邀请模式：

 const mongoose = require('mongoose'); const Schema = mongoose.Schema; const bcrypt = require('bcrypt-nodejs'); //define model const invitationSchema = new Schema({ email: { type: String, unique: true, lowercase: true, unique: true }, inviter: String, company: String, companyCode: String, created: Date, auth: { token: String, used: Boolean, expires: Date, } }); invitationSchema.pre('save', function (next) { const invitation = this; bcrypt.genSalt(10, (err, salt) => { const tomorrow = new Date(); invitation.created = tomorrow; tomorrow.setDate(tomorrow.getDate() + 1); if (err) { return next(err); }; invitation.auth = { token: salt, used: 0, expires: tomorrow }; next(); }); }); //create model class const ModelClass = mongoose.model('invitation', invitationSchema); //export model module.exports = ModelClass;

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