My view engine is jade/pug I am trying to iterate and display the values from the database. I am not getting an error but its not displaying the values. Thanks for the help!
app.js
const express= require('express');
const path = require('path')
const mongoose = require('mongoose')
const bodyParser = require('body-parser')
mongoose.connect('mongodb://localhost/userInfo')
let db = mongoose.connection;
db.on('error',(error) => console.log(error));
db.once('open',() => console.log('Connected to Mongodb'))
const app = express()
// parse application/x-www-form-urlencoded
app.use(bodyParser.urlencoded({ extended: false }))
// parse application/json
app.use(bodyParser.json())
let UserInfo = require('./models/user_info')
app.set('views',path.join(__dirname,'views'))
app.set('view engine','pug')
app.get('/',(req,res) => {
UserInfo.find({},function(err,info){
if(err){
console.log(err);
}else{
res.render('tabel',{
title:'user report',
info:info
});
}
})
})
user_info.js //shema
let mongoose = require('mongoose');
//Userinfo Schema
let userInfoSchema = mongoose.Schema({
name:{
type:String,
required:true
},
studentID:{
type:String,
required:true
},
dept:{
type:String,
required:true
}
});
let UserInfo = module.exports = mongoose.model('UserInfo',userInfoSchema);

Answer 1

In your model, you are pointing the collection name UserInfo, but your data are in 'info' collection.
So, change the collection name explicitly in your model.
Your user_info.js (schema) should be,
let mongoose = require('mongoose');
let userInfoSchema = mongoose.Schema({
name:{
type:String,
required:true
},
studentID:{
type:String,
required:true
},
dept:{
type:String,
required:true
}
});
let UserInfo = module.exports = mongoose.model('UserInfo', userInfoSchema, 'info');
In the last line, I pass the third argument, to indicate the collection name to info.
