ruby-on-rails - 如何为 Rabl 的集合分页

Question

我有这个模板:

# app/views/posts/index.rabl
collection @posts => :posts
attributes :id, :title, :subject
child(:user) { attributes :full_name }
node(:read) { |post| post.read_by?(@user) }

女巫归来:

{
    "posts": [
        {
            "post": {
                "id": 5,
                "title": "...",
                "subject": "...",
                "user": {
                    "full_name": "..."
                },
                "read": true
            }
        }
    ]
}

我想添加一些分页参数以呈现这个:

{
    "posts": [
        {
            "post": {
                "id": 5,
                "title": "...",
                "subject": "...",
                "user": {
                    "full_name": "..."
                },
                "read": true
            }
        }
    ],
    "total": 42,
    "total_pages": 12
}

有什么想法吗？非常感谢!

对不起，我的菜鸟问题，自述文件已经回答了。下面是一个分页示例:

object false

node(:total) {|m| @posts.total_count }
node(:total_pages) {|m| @posts.num_pages }

child(@posts) do
  extends "api/v1/posts/show"
end

注意:我正在使用 Kaminari用于分页。
