Viewsreq.body is undefined - only default mongodb id is getting pushed
I have been trying to use post request to insert data to the mongodb using mongoose, however I see that req.body is being shown as undefined. document is getting inserted in database, however only default object id is getting inserted.
This is how I send request to Postman
{ name:"wewe", price:43}
//Post.js
const mongoose = require('mongoose');
mongoose.connect("mongodb://localhost/tutorialkart");
const productSchema = mongoose.Schema({
name: String,
price: Number
});
module.exports = mongoose.model('Groduct', productSchema);
//app.js
var express = require('express')
var bodyParser = require('body-parser')
var Post = require('./Post')
var app = express()
app.use(bodyParser.json())
app.post('/api/posts', function (req, res, next) {
var post = new Post({
name: req.body.name,
price: req.body.price
})
console.log("Log "+post.name );
post.save(function (err, post) {
if (err) { return next(err) }
res.json(201, post)
})
})
app.listen(3000, function () {
console.log('Server listening on', 3000)
})

There are two issues with your request in Postman (you removed the screenshot which showed these issues):
- it's not formatted as proper JSON, but as a Javascript object
- you're sending it as
text/plain, notapplication/json

One of two things is happening:
- Either you aren't setting a
Content-Typeheader in the request so the JSON parsing middleware you set up isn't being triggered or - You have, but since your JSON is invalid, it is failing to parse it.
You have to write valid JSON!
You can test your JSON with JSON Lint.
In particular, property names in JSON must be strings and cannot be identifiers. Strings in JSON must be delimited with " characters.

Your screenshot is not visible/trouble opening the screenshot. You need to be more specific with your question.
I think mongoose.connect("mongodb://localhost/tutorialkart"); here you need to specify the PORT localhost:27017
Make sure you defined the names "name" and "price" in your HTML/EJS and setting their value as the data you are trying to insert into database.Use new before mongoose.model, mongoose.Schema
app.use(bodyParser.json())should beapp.use(bodyParser.urlencoded({ extended: true }));
