append_around_filter(*filters)

public

The passed filters will have their before method appended to the array of filters that’s run both before actions on this controller are performed and have their after method prepended to the after actions. The filter objects must all respond to both before and after. So if you do append_around_filter A.new, B.new, the callstack will look like:

  B#before
    A#before
    A#after
  B#after

# File actionpack/lib/action_controller/filters.rb, line 223
      def append_around_filter(*filters)
        conditions = extract_conditions!(filters) 
        for filter in filters.flatten
          ensure_filter_responds_to_before_and_after(filter)
          append_before_filter(conditions || {}) { |c| filter.before(c) }
          prepend_after_filter(conditions || {}) { |c| filter.after(c) }
        end
      end

around_filter do |controller, action|
do_your(:stuff) do
  action.call
end
end
