Error: The filter argument must be in object form

Currently I am in the process of developing a REST API with an endpoint for posting movies. The request body is expected to contain only the movie title, which needs to be validated for presence. Upon receiving the title, I need to fetch other movie details from themoviedb and then save them to the application database.

app.post('/movies', (req, res) => {
        request('https://api.themoviedb.org/3/discover/movie?callback=JSONP_CALLBACK&sort_by=popularity.desc&api_key=2931998c3a80d7806199320f76d65298', function (error, response, body) {
            console.log('error:', error); // Print the error if one occurred and handle it
            console.log('statusCode:', response && response.statusCode); // Print the response status code if a response was received

          });
        db.collection('movies').findOneAndUpdate(req.body.title,{
            title: 'Avengers',
        },(err, result) => {
            if (err) {
                res.send({
                    'error': 'An error has occured'
                });
            } else {
                res.send(result.ops[0]);
            }
        });
});

After running the application, I encountered an error. As I am new to Node.js and still learning, I would appreciate any guidance on what I might be doing wrong here.

Answer №1

Utilize the $eq operator within the filter object $eq

{ <field>: { $eq: <value> } }

Incorporate this into the code snippet:

app.post('/movies', (req, res) => {

    /* code ... */

    let { title } = req.body

    db.collection('movies').findOneAndUpdate({ title: { $eq: title } }, { title: 'Avengers' }, (err, result) => {
        if (err) {
            res.send({ 'error': 'An error has occurred' });
        } else {
            res.send(result.ops[0]);
        }
    });

});

Answer №2

Experiment with this suggestion:

db.collection('movies').findOneAndUpdate({title:req.body.title},{
          $set:{
           'Avengers'
          }})
