Subject: [Ruby-aws-develop] Turk notifications
Message-ID: <4934D99F.5020305@thestever.net>

I set up mechanical turk for notifications when a HIT gets completed. 
When it happens, the amazon server contacts my webserver with a GET 
request.

This is probably a basic question, but what aws method do I use to 
process the incoming GET request? It looks like this (I unencoded it for 
your reading convenience):
Event.1.HITId => 12345678901234567890
Event.1.HITTypeId => 09876543210987654321
Event.1.AssignmentId => 1234567890123456789012345678901234567890
Event.1.EventType => AssignmentSubmitted
Event.1.EventTime => 2008-11-30T01:33:03Z
Event.2.HITId => 12345678901234567890
Event.2.HITTypeId => 09876543210987654321
Event.2.AssignmentId => 1234567890123456789012345678900987654321
Event.2.EventType => AssignmentSubmitted
Event.2.EventTime => 2008-11-30T01:33:03Z
Version => 2006-05-05
Signature => xxxxxxxxxxxxxxx
Timestamp => 2008-11-30T01:33:07Z
action => receive_message
method => Notify
controller => ask

SimplifyAnswer doesn't seem to work. Anyone know the answer?

Hi Steve,

RubyAWS doesn't currently have a helper function for simplifying event  
notifications.  What you're getting back is a hash, which should be  
perfectly usable.  The only complicated part is the "Event. 
1.Attribute" vs "Event.2.Attribute" part.  That's the standard way of  
encoding a nested hash as a single-level hash.

{XXX.1.YYY => ZZZ}  maps to  { XXX => [ {YYY => ZZZ} ] }

In my own Rails code that processes events, i typically do something  
like this:

i=1
while !params["Event.#{i}.EventType"].nil?
	event_type = params["Event.#{i}.EventType"]
	hit_id = params["Event.#{i}.HITId"]
	case event_type
	when "HITReviewable"
		# do stuff
	when "AssignmentSubmitted"
		assignment_id = params["Event.#{i}.AssignmentId"]
		# do stuff
	end
end

i'm sure it wouldn't be to hard to write some code that converted the  
single-level hash into a multi-level hash as well, but i don't have  
the time right this moment, and i'm not sure it would really help that  
much.

Good luck, and if you still need help, let the list know.

-David

Thanks. Once I brush up on my ruby skills, I'll try to donate some code 
to add a helper function. I'm still a ruby newbie (probably by your 
standards).
