How to get over path requried error in mongoose - node.js

Question

I am trying to make this web page to upload the books and there links but it always show the following error
const mongoose = require('mongoose');
const BookSchema = new mongoose.Schema({
name: {
type: String,
required: true
},
authour: {
type: String,
required: true
},
discription: {
type: String,
},
link: {
type: String,
required: true
}
})
const Book = mongoose.model('books', BookSchema);
module.exports = Book ;
This is the schema I am using but it keeps showing
UnhandledPromiseRejectionWarning:
ValidationError: books validation failed: link: Path `link` is required., authour: Path `authour` is
required., name: Path `name` is required. at
model.Document.invalidate (E:\mystletainn\node_modules\mongoose\lib\document.js:2688:32) a
app.js code that I have been using
const express = require('express');
const app = express();
const path = require('path');
const mongoose = require('mongoose');
//const methodOverride = require('method-override')
const books = require('./models/books');
mongoose.connect('mongodb://localhost:27017/books', { useNewUrlParser: true, useUnifiedTopology: true
})
.then(() => {
console.log("MONGO CONNECTION OPEN!!!")
})
.catch(err => {
console.log("OH NO MONGO CONNECTION ERROR!!!!")
console.log(err)
})
app.use(express.static(path.join(__dirname, 'public')))
app.set('view engine', 'ejs');
app.set('views', path.join(__dirname, '/views'))
app.use(express.urlencoded({ extended: true }));
//app.use(methodOverride('_method'))
app.get('/', async (req, res) => {
const { name } = req.query;
if (name) {
const book = await books.find({name})
res.render('main', { book, name })
} else {
const book = await books.find({})
res.render('main', { book })
}
})
app.get('/upload', async (req, res) => {
const { name } = req.query;
if (name) {
const book = await books.find({name})
res.render('/', { book, name })
} else {
const book = await books.find({})
res.render('upload',{book})
}
})
app.post('/', async (req, res) => {
const newBook = new books(req.body);
// await newBook.save();
console.log(newBook)
res.redirect(`/`)
})
app.listen(3000, () => {
console.log("LISTENING ON PORT 3000")
})
I have tried to resolve it but it is always giving the same error I am not able to save this to the const newbook.even the console.log shows only the id not the form data

Answer 1

You have to set link.required to false or send it with your request body.

Answer 2

You need to change your post method in something like that,
const newBook = new books({
name:req.body.name,
authour:req.body.author,
discription:req.body.description,
link:req.body.link
})
