How does findByIdAndUpdate work?

Question

JavaScript

Doesn't find the record in the second case, everything works in the first one. Help me understand why.

app.post('/pari', function (req, res, next) {
    Pari.findById("55058fc4e9cbc78c1b9973d2", function(err, par){
       console.log(par); 
    });
        Pari.findByIdAndUpdate("55058fc4e9cbc78c1b9973d2", {date: Date.now, active: true}, function(err, curPari){
            console.log(curPari);
        });
});

If I understood everything correctly, then you want to update the date and status for the document in the second case. For this you need to use "Update operators" mongodb. Your request should look something like this

Pari.findByIdAndUpdate("55058fc4e9cbc78c1b9973d2", {$set:{date: Date.now, active: true}}, function(err, curPari){
            console.log(curPari);
        });

You can read more in the documentation docs.mongodb.org/manual/reference/operator/update-field
