will_paginate JSON 数组

Question

决定使用 Redis 对我的站点进行 JSONify。如何让 will_paginate 与 json 一起工作？

# games.html.erb
<%= js_will_paginate @games, renderer: BootstrapPagination::Rails, class: 'pagination-sm', previous_label: "&#8592;".html_safe, next_label: "&#8594;".html_safe, page_links: false %>

这是我得到的错误：

# undefined method `total_pages' for #<Array:0x007f90ebc05cf0> ln 23 of will_paginate_helper.rb
ln23: will_paginate(collection, options.merge(:renderer => WillPaginateHelper::WillPaginateJSLinkRenderer))

还有我的will_paginate_helper：

# will_paginate_helper.rb
module WillPaginateHelper
  class WillPaginateJSLinkRenderer < BootstrapPagination::Rails
    def prepare(collection, options, template)
      options[:params] ||= {}
      options[:params]['_'] = nil
      super(collection, options, template)
    end

    protected
    def link(text, target, attributes = {})
      if target.is_a? Fixnum
        attributes[:rel] = rel_value(target)
        target = url(target)
      end

      @template.link_to(target, attributes.merge(remote: true)) do
        text.to_s.html_safe
      end
    end
  end

  def js_will_paginate(collection, options = {})
    will_paginate(collection, options.merge(:renderer => WillPaginateHelper::WillPaginateJSLinkRenderer))
  end
end

当我在 nomethoderror 异常下使用 cli 时...

>>  collection
=> [{"id"=>8199, "start_time"=>nil, "game_date"=>"2016-10-23", ... etc }]
>> collection.first
=> {"id"=>8199, "start_time"=>nil, ... etc

我是否需要将 collection 转换为 will_paginate 可以使用的东西，或者我 re-write/override js_will_paginate？谢谢！

想通了。

将 require 'will_paginate/array' 添加到我的 will_paginate_helper.rb，然后在 .to_json 之后对集合进行分页，例如在我的助手（或你的控制器）中：

games = Game.order(game_date: :desc).postgame.to_json
@games = Oj.load games
@games = @games.paginate(page: params[:page], per_page: 10)

像以前一样使用 will_paginate 或 js_will_paginate。
