I install the ActiveMessaging gem under OS X Snow Leopard 10.6.5 and
created a rails application to send messages to an Amazon SQS queue
and process them. I followed the 10 minute quick start on the website,
but chose to create a processor called "Simple".
Using the AWS tools I can see that messages are sucessfully added to
SQS, but when I run the poller, it fails with a message
"NoMethodError: undefined method `name' for nil:NilClass". See the
stack trace below.
I created several rails applications, switched between plugin and gem,
tried different queue names, but with no luck. I even tried to send
various types of data, but still no luck.
Any ideas?
My config/messaging.rb looks as follows:
ActiveMessaging::Gateway.define do |s|
s.destination :simple, "simple_queue"
end
The processor looks as follows:
class SimpleProcessor < ApplicationProcessor
subscribes_to :simple
def on_message(message)
data = YAML.load message
logger.debug "#{Time.now} SimpleProcessor received:
#{data[:message]} on #{data[:time]}"
end
end
and config/broker.yml looks as follows:
development:
adapter: asqs
access_key_id: XXXXX
secret_access_key: XXXXX
test:
adapter: asqs
access_key_id: XXXX
secret_access_key: XXXXX
production:
adapter: asqs
access_key_id: XXXX
secret_access_key: XXXXX
The stacktrace for "poller run" is as follows:
