append_around_filter

v1.2.6 - Show latest stable - Class: ActionController::Filters::ClassMethods

append_around_filter(*filters, &block)

public

If you append_around_filter A.new, B.new, the filter chain looks like

  B#before
    A#before
      # run the action
    A#after
  B#after

With around filters which yield to the action block, #before and #after are the code before and after the yield.

# File actionpack/lib/action_controller/filters.rb, line 290
      def append_around_filter(*filters, &block)
        filters, conditions = extract_conditions(filters, &block)
        filters.map { |f| proxy_before_and_after_filter(f) }.each do |filter|
          append_filter_to_chain([filter, conditions])
        end
      end

do_your(:stuff) do
  action.call
end
