RailsAdmin custom action to restore soft deleted records

问题

I am using Rails 4.1.14 with rails_admin 0.8.1, mongoid 5.0 and mongoid_paranoia. I created RailsAdmin custom action to restore soft deleted Users.

class Restore
  ...
  register_instance_option :controller do
    Proc.new do
      object.restore
      ...
    end
  end
end

But I keep getting

User with id '5695997df5740c17b0000002' could not be found

From my develoment.log

Started GET "/admin/user/5695997df5740c17b0000002/restore" for 127.0.0.1 at 2016-01-12 16:35:04 -0800
Processing by RailsAdmin::MainController#restore as HTML
  Parameters: {"model_name"=>"user", "id"=>"5695997df5740c17b0000002"}
MONGODB | localhost:27017 | rails425_dev.find | STARTED | {"find"=>"users", "filter"=>{"deleted_at"=>nil, "_id"=>BSON::ObjectId('56956c76f5740c1d68000000')}, "limit"=>-1}

The problem is per default_scope query filters out records where deleted_at is not nil. Any suggestions on how to override it?

Unfortunately, I'll have to list this as an answer because I do not have the reputation to comment.

I believe your question may be answered here: How do I show unscoped models in Rails Admin?

The way I'd approach it is to create a scope that does satisfy my requirements for RailsAdmin and use that scope instead; that said, in general I try to avoid default_scope whenever possible.
