我的帖子对象包含一组评论对象，我需要根据偏移量和限制(分页)填充评论.

My Post Object contains an array of Comments Object, I need to Populate Comments based on offset and limit (Paginated).

它适用于 mongoose API，但我需要它与 mongoose-paginate-v2.

It works with mongoose API but I need it with mongoose-paginate-v2.

const post = await Post.findById(req.params.id) .populate("author") .populate("manufacturer") .populate({ path: "comments", populate: "author", options: { sort: { created_at: -1 }, skip: (pageNumber - 1) * limit, limit: limit, }, })

它必须使用 mongoose-paginate-v2 框架，因为我需要一些额外的属性，例如 total.

It has to be with mongoose-paginate-v2 framework because I need some extra properties like total.

推荐答案

document.paginate(filter, options).then(async function(result) where in the option there will be populate: { path : 'item1', populate : { path : 'item2' } },
