我有四种类型的 Rawscores 我想在分页表中一起显示。

代码如下所示：

@facebook_scores_today = Rawscore.where(:channel_string => "Facebook", :project => @project, :created_at.gt => Time.now.beginning_of_day)

@youtube_scores_today = Rawscore.where(:channel_string => "Youtube", :project => @project, :created_at.gt => Time.now.beginning_of_day)

@twitter_scores_today = Rawscore.where(:channel_string => "Twitter", :project => @project, :created_at.gt => Time.now.beginning_of_day)

@influence_scores_today = Rawscore.where(:channel_string => "Influence", :project => @project, :created_at.gt => Time.now.beginning_of_day)

Rawscore 有一个具有多个值的哈希作为表的属性，具体取决于:channel_string.

我该怎么办？任何可以帮助“will_paginate”或“kaminari”的宝石？

更新（这是我的 Rawscore 模型）

class Rawscore
  include Mongoid::Document
  include Mongoid::Timestamps::Created #for created_at field

  belongs_to :channel
  belongs_to :project
  field :values, type: Hash
  validates :values, :presence => true

end

我想在 Rawscore 模型中显示 :values Hash 的键值。

Kaminari 可以对数组进行分页，但效率不高，因为 Active Record 将实例化所有检索到的记录（即，如果您有 10000 条记录并且只想显示 100 条，那么内存中将有 10000 个 AR 对象）

Kaminari.paginate_array(my_array_object).page(params[:page]).per(10)

相反，您可以考虑加入您的查询并使用查询分页

scores_today = Rawscore.where(
  :channel_string => ["Facebook", "Youtube", "Twitter", "Influence"], 
  :project => @project, :created_at.gt => Time.now.beginning_of_day
).page(params[:page])

问题的答案在于使用 WillPaginate::Collection 创建自己的分页结构。
