Make Active Record instance methods asynchronous using resque.
Works with Ruby ~> 1.9, Rails ~> 3 and Resque ~> 1.17. (Probably works with earlier versions too -- but why?)
class User < ActiveRecord::Base # Not needed! This is done using a hook on ActiveRecord::Base. # include Resque::Plugins::Async::Method def preprocess_avatar_for_a_long_time # do stuff end async_method :preprocess_avatar_for_a_long_time def send_a_very_long_email # do stuff end async_method :send_a_very_long_email, queue: 'emails' end u = User.find(1) u.preprocess_avatar_for_a_long_time # => queued in 'users' queue u.send_a_very_long_email # => queued in 'emails' queue u.sync_send_a_very_long_email # => happens right away!
Note that in the test environment, none of this magic happens. You can test the expected output immediately.
Method return values will change.
Resque.enqueue will return
 from an async'ed method.
Sometimes it's nice to async a method that you're including from a module:
module MyExtension extend ActiveSupport::Concern include Resque::Plugins::Async::Method included do async_method :generate_matrix, queue: 'matrices' end def generate_matrix # do stuff end end
- 1.0.1: Update for latest Resque API (true returned from successful queue)
- 1.0.0: Initial release
