ActiveAdmin訪問過濾的集合

我正在嘗試創建一個collection_action，我將對整個已過濾項目的集合進行一些操作。我的問題是，從collection_action內我似乎沒有訪問過濾收集。當我訪問collection時，它只是記錄第一頁上的項目。在我的action_item中，我可以訪問collection_before_scope，這正是我想要的過濾記錄，但是當我嘗試從我的collection_action中訪問它時，這是空的。ActiveAdmin訪問過濾的集合

下面是我current setup試圖找到正確的集合。

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

與最接近相關的問題，我能找到的就是這一點，ActiveAdmin Collection action on filtered data，這似乎並沒有幫助我。

任何幫助將不勝感激。

謝謝

更新：

我仍然有同樣的問題，但我已經想通一些東西。如果我嘗試訪問collection_before_scope之前的集合，則正確的過濾項目位於collection_before_scope中。我不想爲了得到正確的collection_before_scope而訪問集合。不知道爲什麼會發生這種情況。

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
