Mongoose - findByIdAndUpdate - doesn't work with req.body

Question

I have a problem with update documents in mongodb over mongoose.

My model bellow:

var mongoose = require(\'mongoose\');
var bcrypt = require(\'bcrypt-nod         


        

Answer 1

I found the mistake. Note that I'm calling

req.body.user_id

where should be

req.params.user_id

• url is (PUT) http://127.0.0.1:3000/api/users/54724d0fccf520000073b9e3

Further, the req.body would have key value as Text and realized as String object, inside the code. Thus, it is useful to parse the string into JSON using JSON.parse(req.body.user) - while the user is the key and { first_name: 'Michal', last_name: 'Test' } is the value.

console.log(req.body);
var update = JSON.parse(req.body.user);
var id = req.params.user_id;
User.findByIdAndUpdate(id, update, function(err, result){
    if(err){
        console.log(err);
    }
    console.log("RESULT: " + result);
    res.send('Done')
});

Note: the update value is sent to Mongo DB as

{$set: { first_name : 'Michal`, last_name: 'Test' }

You have to use req.params.user_id instead req.body.user_id

exports.updateUser = function (req, res) {   
    console.log(req.body);

    User.findByIdAndUpdate(req.params.user_id,{$set:req.body},{new:true}, function(err, result){
        if(err){
            console.log(err);
        }
        console.log("RESULT: " + result);
        res.send('Done')
    });
};
