Mongoose : .find() doesn't return any document

Question

EDIT : Duplicate of : Mongoose find() not returning result

---

I'm new to nodejs and nosql db.. Today I'm creating an API which read my user collection with two entries :

The problem is that the result is an empty array :

Here is the code :

The model :

var mongoose     = require('mongoose');
var Schema       = mongoose.Schema;

var UserModelSchema   = new Schema({
    _id: Schema.Types.ObjectId,
    user_id:String,
    age:{ type: Number },
    status:String
});

module.exports = mongoose.model('user', UserModelSchema);

app.js :

//...
var User     = require('./app/models/user');
//...
router.route('/users')
// get all the users 
.get(function(req, res) {
    User.find(function(err, users) {
        if (err)
            res.send(err);

        res.json(users);
    });
});

You may want to (even if not necessary) pass the query condition into your find query:

For all users the condition would be: {}

User.find(<condition>, function(err, users) {
            if (err)
                res.send(err);

            res.json(users);
        });

But I found that if the collection was created through some method there is a chance that, your find might not work. Mongoose find() not returning result

This can be the issue. Normal code-wise you are good. I would suggest you to delete of that collection and start by doing inserts from mongoose itself. This will be cleaner

Hope this helps !!

User.find({}, function(err, docs) {}
