Ok So I have a simple node.js / express.js / mongodb app set up here with my config as follows.
var express = require('express'),
mongoose = require('mongoose');
http = require('http');
var app = express();
app.configure(function(){
app.set('port', process.env.PORT || 3000);
app.set('views', __dirname + '/views');
app.set('view engine', 'jade');
//middleware stack
app.use(express.bodyParser());
app.use(express.methodOverride());
app.use(app.router);
app.use(express.static(__dirname + "/public"));
});
mongoose.connect("mongodb://localhost/hello");
The problem lies when I try to make PUT or DELETE requests. My form is this simple
<form method="POST" action="/users/#{user.name}">
<input type="hidden" name="_method" value="PUT"/>
</form>
Now my router catches the route with the express .put() method
app.put('/users/:name', function(req, res) {
var b = req.body;
Users.update(
{ name: req.user.name },
{ name: b.name, age: b.age, email: b.email },
function(err) {
res.redirect('/users/'+b.name);
});
})
When I make the request I simply get a "Cannot PUT" or "Cannot DELETE" error.
I have tried to make this same request via chomes RESTful client with the same result.
I have read a topic witch has the same problem as me although following the comments the answers did not solve my problem.
Questions I have looked into expressjs support for method delete and put without the methodoverride
Are the PUT, DELETE, HEAD, etc methods available in most web browsers?
Along with a few others. I have also referenced the express.js and mongo documentation several times. I just cant think what could be going wrong.
Any help is appreciated.
Update
As Jonathan Lonowski pointed out PUT can also be used, so you can ignore my old answer.
Getting Cannot PUT or Cannot POST errors, means your callback is not executing successfully. My guess is that Users.update is failing, which is why it cannot POST or PUT. Can you check it.
Old answer
Try changing this line
app.put('/users/:name', function(req, res) {
to
app.post('/users/:name', function(req, res) {
since you are trying to submit the form
Is the <form> you listed in a view or a static file under __dirname + "/public"?
Within a static file, the #{user.name} probably isn't being replaced with the user's name and will be treated as a URL Fragment.
The <form> will actually submit to /users/ rather than /users/:name since that's the path:
console.log(url.parse('/users/#{user.name}'));
{ hash: '#{user.name}',
pathname: '/users/',
path: '/users/',
href: '/users/#{user.name}' }
The <form> should be generated from a view if it isn't since the action needs to be dynamic and data-driven. With Jade and assuming user is a member of locals, that would be:
form(method='POST', action='/users/' + user.name)
input(type='hidden', name='_method', value='PUT')
Unless there is strange magic at work, your form makes a POST request, not a PUT. If you want to PUT, I would suggest using the jQuery.ajax function with a type: 'PUT' parameter, like this answer, from a form handler, see jQuery.submit. Don't forget to return false so that the form doesn't submit twice.
