ActiveAdmin Access过滤的集合 [英] ActiveAdmin Access filtered collection
问题描述
我正在尝试创建一个collection_action，在其中我将对整个过滤后的项目集合进行处理。我的问题是，在collection_action中，我似乎无权访问已过滤的集合。当我访问集合时，只有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，此记录为空。
I'm trying to create a collection_action where I'm going to do something with the entire collection of filtered items. My problem is that from within the collection_action I don't seem to have access to the filtered collection. When I access collection it is only the items that are on the first page of records. In my action_item I have access to collection_before_scope which is exactly the filtered record I want, but this is empty when I try to access it from within my collection_action.
下面是我的当前设置，试图找到正确的集合。
Below is my current setup attempting to find the correct collection.
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，对过滤数据进行ActiveAdmin收集操作，似乎并没有帮助我。
The closest related question I could find was this, ActiveAdmin Collection action on filtered data, which didn't seem to help me out.
任何帮助将不胜感激。
谢谢
更新：
我仍然有同样的问题，但是我发现了一些问题。如果我尝试在 collection_before_scope 之前访问集合，则正确的过滤项在collection_before_scope中。我不想只为了获取正确的 collection_before_scope 即可访问收藏集。不知道为什么会这样。
I still have the same problem, but I have figured something out. If I try to access the collection before the collection_before_scope then the correct filtered items are in collection_before_scope. I don't want to have to access the collection just to get the correct collection_before_scope though. Not sure why this would happen.
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
推荐答案
尝试一下：
puts filtered collection = + apply_filtering（collection）.to_yaml （在您调用 collection 之前）
为什么您在第一次访问集合后会到达正确的过滤集合？
Why do you reach the correct filtered collection after you accessed the collection first?
集合方法将调用 find_collection 方法： https://github.com/activeadmin/activeadmin/blob/master/lib/active_admin/resource_controller/data_access.rb#L32
find_collection 方法将调用 apply_filter 方法： https://github.com/activeadmin/activeadmin/blob/master/lib/active_admin/resource_controller/data_access.rb#L50
