Testing REST routes with curl -X PUT returns 404

Question

I study the MEAN stack and follow the MEAN tutorial at thinkster.io https://thinkster.io/mean-stack-tutorial/

I am in the section "Opening REST Routes". I am trying to print the top using curl with the command:

curl -X PUT http://localhost:3000/posts/55387047f2334d2
c227e8079/upvote

The following error messages appear:

C:\Users\Michael\Desktop>curl -X PUT http://localhost:3000/posts/55387047f2334d2
c227e8079/upvote
<h1>Not Found</h1>
<h2>404</h2>

My mongoose schema is defined relative to module.exports = app in app.js, so I'm not sure what else to do. I tested my copy and paste skills and there are no typos.

Answer 1

Restarting the node server solved the problem for me

router.put('/posts/:post/upvote', function(req, res, next) {
  req.post.upvote(function(err, post){
    if (err) { return next(err); }

    res.json(post);
  });

REST Routes > Pre-Loading Objects :

router.param('post', function(req, res, next, id) {
  var query = Post.findById(id);

  query.exec(function(err, post) {
    if (err) { return next(err); }
    if (!post) { return next(new Error('can\'t find post')); }

    req.post = post;
    return next();
  });
});

:

var query = Post.findById(id);

:

var query.exec(function(err, post) {
