I want to print all documents of "members" collection. I used find() function but it throw error : find() is not a function.

In member_model.js (in models/admin folder):

var mongoose = require('mongoose');
var Schema = mongoose.Schema;
var MemberSchema = new Schema({
  username: String,
  password: String
});
module.exports = mongoose.model('members', MemberSchema);

In index.js (in controllers/admin folder):

const members = require('../../models/admin/member_model');
var Members = new members();
Members.find({}, function (err, resDB) {
  assert.equal(err,null);
  console.log(json(resDB));
});

I checked connecting to DB, it's still ok. I also read some other questions but any suitable answer for my problem.

Note more i tested like this :

In auth.js (in controllers/admin folder):

const members = require('../../models/admin/member_model');
var Members = new members();
Members.username = req.body.username;
Members.password = req.body.password;
var refererURL = req.headers.referer;

Members.save((err, resSave) => {
  if(err) {
    console.log(err);
    res.redirect(refererURL);
  } else {
    console.log('saved');
  }
})

Members.find({}, function (err, resDB) {
  assert.equal(err,null);
  console.log(json(resDB));
});

Members.save() is ok, but Members.find() still error.

Help me what my error is ? Thanks!

Try the below code:

In member_model.js (in models/admin folder):

Change the below code to :

// module.exports = mongoose.model('members', MemberSchema);
module.exports = {
  memberCollection: mongoose.model('members', MemberSchema)
}

In index.js (in controllers/admin folder):

const members = require('../../models/admin/member_model');
members.memberCollection.find({}, function (err, resDB) {
  assert.equal(err,null);
  console.log(json(resDB));
});
