在猫鼬上填充和分页子文档 [英] Populate and Paginate an sub document on Mongoose

问题描述

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'
        }
      },
