Rails - Jul 2008 - Getting access to request.env in a model observer?

Does anyone know how I would get access to the request.env object  
within a model observer?  I''m using restful_authentication to send  
email, and need to include some of that request data in there.

I have it working with normal ActionMailer stuff, but can''t figure out
how to do it in an observer.

Thanks,
Wade

You can''t. Request information is related to controllers and views and
should not be made available to models.

Look at Restful authentication and see how it handles that - they use
attr_accessor to store data.


This is a really dumbed-down approach but you could do this:

class ModelObserved < AR::Base

  attr_accessor :request_info

  # rest of your code
end



class ModelObservedObserver < AR::Observer

   observes ModelObserved

   def after_save(record)
      unless record.request_info.blank?
        # do stuff with this
      end
   end


end

Then in your controller you just need to make sure you pass the request.env
stuff to the model.


The other way to do it is to use cache_sweepers instead of observers.
Acts_as_audited does that so you might learn something from that code.

Thanks - I used an attr_accessor and it seems to do the trick!
