Authentication Fail with MongoDB Compass Community I've just created a new MongoDB account and I'm now trying to connect the free cluster I created via MongoDB Compass Community application but I'm getting a 'Authentication Fail' error being displayed. This is what I've checked so far: From my MongoDB Clusters section when I clicked on the Connect (…) button which then gives you various options. From there, I selected 'Connect with MongoDB Compass' and copied the connection string. This was detected as expected by the Compass and the information was filled automatically in all the relevant fields and I also filled the password by copy/pasting it into the relevant field. 100% sure it is correct. I checked that the username used was indeed set up as an admin and it is. I checked my Authentication database was correct and it is. I've checked that my public IP was added to the whitelist and it is. The only thing I've noticed is that when I added my p...

node-fibers : yielding data out of a Fiber I just started working with node-fibers to actually try out something I had in mind to make it easier to make mongoose queries a little more easy to deal with. Unfortunately , I don't seem to understand what I'm doing wrong to get the users returned using the yield() to the main function that called Fiber. users yield() var Fiber = require("fibers"); var mongoose = require("mongoose"); var User = require('./user'); mongoose.connect('mongodb://localhost/fibers'); function wrapper() { let f = Fiber(function(){ var results; var fiber = Fiber.current; User.find({},function(err,users){ var results = Fiber(function(){ fiber.run(users); }).run(); }) results = Fiber.yield(); Fiber.yield(results); }); return f.run.bind(f); } var result = wrapper()(); console.log(result); use sync in...

Retrieving User Collection from API / MongoDB but exclude Password Field? I am constructing an api which retrieves articles. I also have users in my database, and would like to have one endpoint which returns the user. /api/users/:userid . This returns something along these lines: /api/users/:userid { "articles": , //array w. references to articles the user has written "_id": "5b1321321bcda0e3364251d7e4a", "email": "user@email.com", "password": "$2a$1231241gi14k41k42bk12bh3k127iP/k1LAqwPdbgF/bXXpRia", "__v": 0 } -- However, I am not sure whether it's a good idea to return the (encrypted) password in the API. Can I somehow exclude this field, or would you recommend to store emails + user_ids in a separate collection on mongodb, or how are things like this usually handled? 2 Answers 2 you can use Project Fields to Retu...
