Pagination on subdocuments

[Mdhaker]

This is my schema
const schema = new mongoose.Schema({ // User profile data saved here profile : { }, trainings:[training], // User training courses data saved here sessions:[session], slug: { type: String }, path: { type: String }, slugs: { type: [String] }, createdAt: { type: Date, default: Date.now }, updatedAt: { type: Date }, status: { type: String, enum: userStatus, default:"inactive" }, }
Is there away to paginate the array of subdocuments lik trainings and sessions ?

@Mdhaker - Have you possibly got a solution to this? Looking to do something similar

[carvalhoviniciusluiz]

you could use aggregation framework - $unwind the array of subdocuments and then use $sort and $limit.

If I understand correctly, in case of using aggregation framework we lose all Mongoose features, like methods, virtuals, post/pre hooks etc, because returned result is raw object, not wrapped by Mongoose.

Is it right?

If yes, then using aggregation with Mongoose don't have any sense.
