ruby-on-rails – ActiveAdmin Access过滤集合

我正在尝试创建一个collection_action,我将在整个过滤项集合中执行某些操作.我的问题是,在collection_action中,我似乎无法访问过滤的集合.当我访问集合时,它只是记录第一页上的项目.在我的action_item中,我可以访问collection_before_scope,这正是我想要的过滤记录,但当我尝试从我的collection_action中访问它时,这是空的.

以下是我目前的设置,试图找到正确的集合.

collection_action :dosmth,:method => :get do
  # collection_before_scope will be empty
  puts "collection_before_scope = " + collection_before_scope.to_yaml

  # collection will return only the filtered items on the front page
  puts "collection = " + collection.to_yaml

  redirect_to :back,notice: 'Something happening'
end

action_item :only => :index do
  # collection_before_scope will return the full collection that I'm looking for.
  puts "collection_before_scope = " + collection_before_scope.to_yaml 

  link_to "Export",dosmth_admin_earned_points_path(controller.params)
end

我能找到的最接近的相关问题是这个,ActiveAdmin Collection action on filtered data,这似乎没有帮助我.

任何帮助将不胜感激.

谢谢,

更新：

我仍然有同样的问题,但我已经找到了一些东西.如果我尝试在collection_before_scope之前访问该集合,则正确的过滤项目在collection_before_scope中.我不想只是为了获得正确的collection_before_scope而访问该集合.不知道为什么会这样.

collection_action :dosmth,:method => :get d0
  # collection will return only the filtered items on the front page
  puts "collection = " + collection.to_yaml

  # collection_before_scope will be correct because I accessed the collection first.  why???
  puts "collection_before_scope = " + collection_before_scope.to_yaml

  redirect_to :back,notice: 'Something happening'
end
