I'm doing a tutorial in the MEAN Machine book, chapter about route APIs.
Full code posted here: https://gist.github.com/leongaban/6db44e513db4ca9e784f
The following code is the API to get all users, and then to get a user by a certain id.
Get all users:
// api/users
apiRouter.route('/users')
// create a user (accessed at POST http://localhost:8615/api/users)
.post(function(req, res) {
// create a new instance of the User model
var user = new User();
// set the users information (comes from the request)
user.name = req.body.name;
user.username = req.body.username;
user.password = req.body.password;
// save the user and check for errors
user.save(function(err) {
if (err) {
// duplicate entry
if (err.code == 11000)
return res.json({ success: false, message: 'A user with that username already exists. '});
else
return res.send(err);
}
// return a message
res.json({ message: 'User created!' });
});
})
// get all users (access at GET http://localhost:8615/api/users)
.get(function(req, res) {
User.find(function(err, users) {
if (err) return res.send(err);
// return the users
res.json(users);
})
});
Follow the above is the code to get just 1 user based on id:
// api/users/:user_id
apiRouter.route('/users/:user_id')
// get the user with that id
// (accessed at GET http://localhost:8615/api/users/:user_id)
.get(function(req, res) {
User.findById(req.params.user_id, function(err, user) {
if (err) return res.send(err);
// return that user
res.json(user);
})
// update the user with this id
.put(function(req, res) {
// use our user model to find the user we want
User.findById(req.params.user_id, function (err, user) {
if (err) return res.send(err);
// update the users info only if its new
if (req.body.name) user.name = req.body.name;
if (req.body.username) user.username = req.body.username;
if (req.body.password) user.password = req.body.password;
// save the user
user.save(function(err) {
if (err) return res.send(err);
// return a message
res.json({ message: 'User updated!' });
});
})
})
// delete the user with this id
.delete(function(req, res) {
User.remove({
_id: req.params.user_id
}, function(err, user) {
if (err) return res.send(err);
res.json({ message: 'Successfully deleted' });
});
});
});
Now going to my localhost:8615/api/users/ I am able to get all the users back
I then select an id from one of the users, for example:
localhost:8615/api/users/54b64c770dedef7c1a7d2c8b
And I get the following error:
TypeError: Object #<Query> has no method 'put'

In my Gist you can see that my headers are set once at the top: https://gist.github.com/leongaban/6db44e513db4ca9e784f
Any idea why I'm having this problem?
You are missing the closing })
for the .get() method. So put is being called on the return of User.findById()
It should be
.get(function(req, res) {
User.findById(req.params.user_id, function(err, user) {
if (err) return res.send(err);
// return that user
res.json(user);
})
}) // <-- was missing
// update the user with this id
.put(function(req, res) {
