Please have a look at code below:
var parties = Party.find({ email: email }, { email: 1, _id: 0 });
this query returns 3 documents.
Now I want to send result and stringify these documents:
response.json(parties);
I get error here because parties contains circular references and does not just contain plain data I need here.
Question is:
How can I stringify result of find() method here?

Answer 1

I know what my mistake was.
MongoDB and it's shell is not the same as Mongoose API.
find() method needs different arguments for both.
The one I needed here is:
Party.find({ 'email': email }, 'email', function (err, parties) { response.json(parties)});
