mongoose error

[Xiscollado]

Hi Jeff,
First of all, your book is awesome, i´m learning a lot.

I have a problem setting up the POST of the username and body as you say in the chapter "Using Mongoose Models with POST Endpoint"

i´m using postman and i get this...

ValidationError: Path body is required., Path username is required.

any clues?
Cheers!

are you actually sending a body in the message with those properties? I would try to just print out the exact body you're receiving to figure out where they're getting lost

[Xiscollado]

Ok, i did this on the POST route

res.json(req.body);
and got this from postman... { }

this is the post:

POST /api/posts HTTP/1.1
Host: localhost:3000
username: Xisco
body: Hi, people!
Cache-Control: no-cache
Postman-Token: 95633eaa-0e11-1cea-de96-f8e50fd410ba
Content-Type: multipart/form-data; boundary=----WebKitFormBoundaryp7MA4YWxkTrZu0gW

and the route at server.js

var Post = require ('./models/post');
app.post('/api/posts', function(req, res, next){

res.json(req.body);

var post = new Post({
    username : req.body.username,
    body: req.body.body
});

post.save(function(err,post){
    if(err){return next(err)};
    res.json(201, post);
});

})

[jdx]

did you add body-parser?

[Xiscollado]

those are the first lines on the file:

var express = require('express'),
bodyParser = require('body-parser'),
app = express();

app.use(bodyParser.json());

[jdx]

oh your body just has Hi, people! as a string, but your controller is expecting a json docuemnt with a username and body

[Xiscollado]

sent this...

Sorry... :(

[jdx]

you need to set the content type to application/json

[Xiscollado]

wtf!?

POST /api/posts HTTP/1.1
Host: localhost:3000
body: {username: 'Xisco', body: 'Hi people'}
Content-Type: application/json
Cache-Control: no-cache
Postman-Token: a2caf2cd-0810-c1c3-8222-f2e886306bea

got
malformed JSON

[jdx]

it's not valid, the labels need quotes

[Xiscollado]

its turning frustrating...

POST /api/posts HTTP/1.1
Host: localhost:3000
body: {'username' : 'Xisco', 'body' : 'Hi, people'}
Content-Type: application/json
Cache-Control: no-cache

I had this same problem with making Posts with the examples from the book using Postman. I could never get it to work using 'form-data' or 'x-www-form-urlencoded'. I could always get it to work using CURL but that's a pain too. So finally I just started using Postman but putting the data in the 'raw' field using the same format for data as the CURL examples and that seems to work. Hope that helps.

Now it works! thanks a lot!
