An addendum to my previous post:
this process works from the rails console:
I've removed the specifics of the model and its contents, but they are
correct when they come back
>>MiddleMan.worker
(:comment_notification_worker).enqueue_action( SomeModel.find(:first) )
{:type=>:do_work, :data=>#<SomeModel:0x25e2944 @attributes={"model
attributes
"}>
, :worker_method
=>:enqueue_action, :worker=>:comment_notification_worker}
=> nil
backgroundrb receives the object and handles it properly, writing to
the database.
if anyone has any thoughts on this disparity in behavior I'd really
appreciate some feedback

I'm working on a suite of workers that all inherit a lot of their

fine when included within my models so the logic there has been
tested and works correctly. the goal here is to be able to be able
to extend a suite of bdrb workers that will have their basic
transactional logic encapsulated in the plugin/module.
I'm thoroughly perplexed and I would love some suggestions on this.
example worker:
class CommentNotificationWorker < BackgrounDRb::MetaWorker
include ActionQueue
set_worker_name :comment_notification_worker
def create(args = nil)
end
end
I'm trying to call it from inside my comment model in
an :after_create hook like so (where self is an instance of class
Comment, and enqueue_action is inherited from the ActionQueue module):
MiddleMan.worker(:comment_notification_worker).enqueue_action(self)
I'm consistently generating this error:
