resque-mission
resque-mission adds Missions (multi-step jobs) to Resque.
Example
require 'resque-mission'
class TestMission < Resque::Plugins::Mission
# specify the queue (string/symbol)
queue :test
attr_reader :a, :b, :c
# called by create_from_options
def initialize(a, b, c)
@a = a
@b = b
@c = c
end
# implement this to rehydrate state from queue
# can modify what's passed to queue!(...) to whatever initialize wants
# eg: fetch an object from db by id, and pass obj to initialize
def self.create_from_options(args={})
new(args['a'], args['b'], args['c'])
end
# steps are executed in the order they are declared here
# each one maps to a method of the same name
step :step1
step :step2
def step1
sleep 2
`echo '#{a} #{b} #{c}' > /tmp/step1.$(date -d "today" +"%Y%m%d%H%M%S").log`
end
def step2
sleep 5
`echo '#{a} #{b} #{c}' > /tmp/step2.$(date -d "today" +"%Y%m%d%H%M%S").log`
end
end
# enqueue
TestMission.queue!({
:a => "Mission",
:b => "Impossible",
:c => "Accomplished"
})
