ActiveAdmin访问过滤的集合

我正在尝试创建一个collection_action，我将对整个已过滤项目的集合进行一些操作。我的问题是，从collection_action内我似乎没有访问过滤收集。当我访问collection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，但是当我尝试从我的collection_action中访问它时，这是空的。ActiveAdmin访问过滤的集合

下面是我current setup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

与最接近相关的问题，我能找到的就是这一点，ActiveAdmin Collection action on filtered data，这似乎并没有帮助我。

任何帮助将不胜感激。

谢谢

更新：

我仍然有同样的问题，但我已经想通一些东西。如果我尝试访问collection_before_scope之前的集合，则正确的过滤项目位于collection_before_scope中。我不想为了得到正确的collection_before_scope而访问集合。不知道为什么会发生这种情况。

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
