I am trying to save this data in my mongodb database:

var Student_Answers = {
  matricNumber: matric,
  Answers:  answers  //This is the array answers = ["A", "B"]
};

This is my schema:

var Student_AnswersSchema = mongoose.Schema({
  matricNumber: String,
  Answers: [
    {
      type: String
    }
  ]
});

And this is where the save function is fired

var save = SA(req.body).save(function(err, data) {
  if (err) throw err;
  res.json(data);
});

The matric appears in the database and also the array name but never the contents of the array

enter image description here

you are saving ``` Answers: answers //This is the array ["A", "B"] ``` is array needs to be array of object – Shibon Dec 23 '19 at 12:17

that is the same thing i did in the code, didnt still work – leonard ikeh Dec 23 '19 at 12:50
What's the output of `console.log(req.body.Answers)` and `console.log(typeof req.body.Answers)` ? – Fraction Dec 23 '19 at 13:05
it logged undefined – leonard ikeh Dec 23 '19 at 13:15
this is what the req.body is looking like: { matricNumber: '22/5698', 'Answers[]': [ 'A', 'B' ] } – leonard ikeh Dec 23 '19 at 13:18
you have an extra `[]` with the `Answers` property, what happens if you try with: `const { matricNumber, 'Answers[]': Answers } = req.body; SA({ matricNumber, Answers }).save...` ? – Fraction Dec 23 '19 at 13:32
This worked thank you very much, but can you also explain to me why this worked and not the other way. – leonard ikeh Dec 23 '19 at 13:39
the name of the property in the schema is `Answers` but it's `Answers[]` in the body and `'Answers' != 'Answers[]'` – Fraction Dec 23 '19 at 13:49
but why is it saving as 'Answers[]' in the body – leonard ikeh Dec 23 '19 at 13:54

I don't know, maybe look at the place where you created the request – Fraction Dec 23 '19 at 14:05
