I am attempting to use the Simple Workflow service to manage jobs for a rails application. I am basing my work off the booking example from the documentation. The rake task looks like:
require "#{Rails.root}/app/helpers/application_helper"
include ApplicationHelper
namespace :swf do
desc 'Start activity worker'
task :activity => :environment do
swf, domain = swf_domain
activity_worker = AWS::Flow::ActivityWorker.new(swf.client, domain, SWF_ACTIVITY_TASK_LIST, ScrapeActivity) { {:use_forking => false} }
activity_worker.start
end
desc 'Start workflow worker'
task :workflow => :environment do
swf, domain = swf_domain
worker = AWS::Flow::WorkflowWorker.new(swf.client, domain, SWF_WORKFLOW_TASK_LIST, ScrapeWorkflow)
worker.start
end
desc 'Queue activities'
task :scrape => :environment do
swf, domain = swf_domain
my_workflow_client = workflow_client(swf.client, domain) { {:from_class => "ScrapeWorkflow"} }
Product.all.each do |product|
$workflow_execution = my_workflow_client.start_execution(product.asin)
end
end
end
The rest of the code is online. I'm using the aws-flow gem (and I added aws-flow-core), but I'm getting an error: uninitialized constant AWS::Flow::ActivityWorker
when I try to run the activity worker.
