通过子-子文档ID查询文档

Question

I have the following schema's:

var Post = new mongoose.Schema({
 'responses': [Response]
});

var Response = new mongoose.Schema({
 'question': Question
});

var Question = new mongoose.Schema({
 'id': 12345
});

How would I query for POSTS that contain RESPONSES that match a certain QUESTION _id. For example: 12345?

Thanks for the help!

Answer 1

I believe this is the query you are looking for

const _id = 'some object id'
Post.find({ 'responses.question._id' : _id }).then((posts) => {
   console.log(posts);
}).catch((err) => console.log(err))
