mongoose

问题 After hours trying to solve this by myself I reach to SO community looking for some light. I'm using passport for user authentication. It's already initialized in my main express.js file as per the docs: app.use(passport.initialize()); I got a index.js file which handles facebook-passport in this manner: Index.js 'use strict'; import express from 'express'; import passport from 'passport'; import auth from '../auth.service'; let router = express.Router(); //this function is defined in the

问题 I'm using MongoMemoryServer to write an integration test. I have two integration test files. When I run the IT tests I see the following. I don't understand why. I'm using jestjs test framework.

The example from that link: class PersonClass { get fullName() { return `${this.firstName} ${this.lastName}`; // compiler error } } PersonSchema.loadClass(PersonClass); The schema's properties are not defined in the class, so the TypeScript compiler says: Property firstName does not exist on type PersonClass. A hack is to use a dummy constructor: constructor(readonly firstName: string, readonly lastName: string) { } However that is hack

问题 This is a followup to Easiest way to copy/clone a mongoose document instance?, which isn't working for me. The following code throws a "cannot edit Mongo _id" field, rather than wiping the ._id and creating a new document in the collection.
