MongoDB CRUD the MVC way with Passport Authentication 62
• findByIdAndRemove()¹²⁰
Since you’re already using the userById() method, you’re going to use the findByIdAndRemove()
method.
In your app/controllers/users.server.controller.js file add a new delete() method:
1 exports.delete = function(req, res, next) {
2 req.user.remove(function(err) {
3 if (err) {
4 return next(err);
5 }
6 else {
7 res.json(req.user);
8 }
9 })
10 };
Now, in app/routes/users.server.routes.js file change the route with the userId parameter to be
like this:
1 app.route('/users/:userId').get(users.read).put(users.update).delete(users.delet\
2 e);
To test the delete method, run node server and issue a DELETE request, example with curl (OFC
replace id] as before):
1 $ curl -X DELETE localhost:1337/users/[id]
Few additional goodies
Indexes
A unique index validates the uniqueness of a document field across a collection. Since you most
likely want the username to be unique, you have to add this to your User model:
