will_paginate JSON支持？ [英] will_paginate JSON support?

问题描述

我怀疑是否有人可以告诉我，如果will_paginate可以支持JSON，或者必须被黑客入侵？

I wonder if anyone could please tell me if will_paginate can support JSON out of the box or if this has to be hacked?

我想添加页面数据到JSON响应，而will_paginate管理分页。

I would like to add page data to the JSON responses while will_paginate manages pagination.

推荐答案

Something in the lines of:

@posts = Post.paginate :page => params[:page]

respond_to do |format|
  format.json {
    render :json => {
      :current_page => @posts.current_page,
      :per_page => @posts.per_page,
      :total_entries => @posts.total_entries,
      :entries => @posts
    }
  }
end

你想要什么格式，你总是可以在WillPaginate :: Collection上定义一个 to_json 方法。

Once you figure out what format you want, you can always define a to_json method on a WillPaginate::Collection.
