How to sort a populated document in find request?

Question

I would like to sort a populated Document from the collection i fetch, i get an error requesting it.

Let\'s admit a Document Group (Group) and \'Member\

Answer 1

This code worked for me and may help you out

Group.find({}).populate('Members').sort({ created_at: -1 })

Answer 2

You can also implicitly specify only required parameters of populate:

Group
  .find({})
  .populate({path: 'Members', options: { sort: { 'created_at': -1 } } })

Have a look at http://mongoosejs.com/docs/api.html#document_Document-populate

Answer 3

This example above works with Mongoose 2.x and above, use this syntax:

Group
  .find({})
  .populate('Members', '_id name', null, { sort: { 'created_at': -1 } })

Answer 4

This worked correctly for me in Mongoose Versions 5 and above.

Clinics.findById(req.params.id).populate({path:'users',options:{ sort:{date : 1}}}).exec(callback);

Answer 5

I ended up needing to populate a nested document, this worked for me:

const video = await Video.findOne({ urlId }) // find video
        .populate('likes user') // populate the likes and owner (user) of video
        .populate({
            path: 'comments', // populate the comments as well,
            options: { sort: { date: -1 } }, // sorting the comments by date
            populate: {
                path: 'user', // and populating the owner (user) of each comment,
                select: 'username, date', // plucking whichever fields necessary from the User model
            },
        })
]);

Answer 6

And for Mongoose 4.x use this syntax:

Kitten.find().populate({
    path: 'owner'
  , select: 'name'
  , match: { color: 'black' }
  , options: { sort: { name: -1 }}
}).exec(function (err, kittens) {
  console.log(kittens[0].owner.name) // Zoopa
})

// alternatively
Kitten.find().populate('owner', 'name', null, {sort: { name: -1 }}).exec(function (err, kittens) {
  console.log(kittens[0].owner.name) // Zoopa
})
