  students is not defined 

controller:

  const express = require('express');
  var router = express.Router();
  const mongoose = require('mongoose');
  const Attendance = mongoose.model('Attendance');

  router.get('/', (req, res) => res.render('attendance/index'));

  router.get('/student', (req, res) => { 
Student.find((err, docs) => { 
    if (!err) { res.render("student", {
                   students: docs
               });
     } else { 
        console.log('Error in retrieving students record :' + err);
         } 
     }); 
  });

  module.exports = router;

student controller:

Solution 1:

When you access router.get('/student' you pass students into the EJS with res.render("student", { students: docs }).

When you access router.get('/' you just say res.render('attendance/index')) and don't pass anything into it, let alone an object that defines students.

You need to do there what you do in /student.
