Mongoose findOneAndUpdate Updating Multiple Fields

Question

The findOneAndUpdate method doesn\'t work properly. I\'m trying to update all the fields all at once but it\'s only updating (setting) the last field. It\'s always only the last

You are using the $set operator multiple times. The correct syntax for $set is :

{ $set: { <field1>: <value1>, ... } }

You need to change your update argument like this:

Book.findOneAndUpdate({ "_id": bookId }, { "$set": { "name": name, "genre": genre, "author": author, "similar": similar}}).exec(function(err, book){
   if(err) {
       console.log(err);
       res.status(500).send(err);
   } else {
            res.status(200).send(book);
   }
});
