Rails - Mar 2007 - Getting HTTP response code from a controller

Hi there, how would I get the HTTP response code (200 OK, 500, etc...)
from a controller after a request have been ''served''?


Thanks

I was able to get the response status after_filter by doing 
response.headers["Status"], but it *only* displays the 200 and 302 
codes. Any ideas how I get get the others (404, 500, etc...) as well?

Thanks

You''ll have to hook it somewhere else (eg, in Mongrel or a monkey/
mixin patch to ActionController::Base).  Your controller won''t be
consulted in the case of a 404 or 500 error.  Those are usually
generated from exceptions.

Is there a reason you need to know about these status codes in your
controller?

Eden Li,

I see what you mean. The reason why I need those status codes is for a 
personal project that I''m doing and I need to store those codes in the 
DB as-they-happen.

Could you give me a starting point for the monkey/mixin patch?

Thanks

Cool, I could have a use for that as well. Let me know if you guys
figure it out. In the meantime I''ll try to do it too.

Here''s a first stab...

# lib/final_response.rb
module FinalResponse
  def self.included(base)
    base.class_eval do
      alias_method :process_without_final_response, :process
      alias_method :process, :process_with_final_response
    end
  end

  def process_with_final_response(*args)
    process_without_final_response(*args)
  ensure
    final_response if respond_to?(:final_response)
  end
end

# app/controllers/my_controller.rb
class MyController < ActionController::Base
  include FinalResponse
  def final_response
    logger.info("status = #{headers[''Status'']}")
  end

  def action
    raise
  end
end

Your final_response method won''t have access to the session, but
you''ll still be OK to access models.

There''s probably a better way to do this, but this should work...
