• written mongo db query code but its not producing results. var cursor = db.collection('user-data').find( { carManufacturer: { $eq: toyota } } );

• can you guys tell me how to fix it providing my code below

router.get('/cars', function(req, res, next) {

  mongo.connect(url, function(err, db) {
    assert.equal(null, err);
    var cursor = db.collection('user-data').find( { carManufacturer: { $eq: toyota } } );

    cursor.forEach(function(doc, err) {
