I hope someone can point out my stupic mistake here as I have wasted
far too much time fiddling with syntax and I just can''t get it. I am
new to BackgroundRB and I am trying to pass 2 ids to my worker.
In my controller I have:
MiddleMan.worker(:process_cv_worker).async_changed_cv(:arg =>
{ :vitae_id => @vitae.id, :current_user_id => current_user.id })
And my worker looks like:
class ProcessCvWorker < BackgrounDRb::MetaWorker
set_worker_name :process_cv_worker
require ''pdf/toolkit''
def create(args)
# this method is called, when worker is loaded for the first time
logger.info "Created vitae worker"
end
def changed_cv(arg)
vitae_id = arg[:vitae_id]
user_name = arg[:current_user_id]
@vitae=Vitae.find(vitae_id)
more code
end
end
However, when I run this code I get Error calling method changed_cv
with on worker process_cv_worker at Thu Nov 03 09:37:56 +0000 2011
undefined method `[]'' for nil:NilClass
The code works fine if I just use @vitae=Vitae.find(1) so I know that
it is not finding the vitae. I am sure i am being stupid but I have
confused myself and am seeking help.
Thanks,
Dan

I do not know if this can help you , but i do experence this kind of things few days ago. The rails process create the record and return the id for you, notice the db not commit actually at this monument, then spawn/fork the worker process, the worker found the record not exist in DB. If you experence the same problem, i recommend you there is a plugin/gem that include after_commit callback, and make the async work after the db commit. -- kevin Sent with Sparrow (http://www.sparrowmailapp.com/?sig) On Thursday, November 3, 2011 at 5:58 PM, DanC wrote:> I hope someone can point out my stupic mistake here as I have wasted > far too much time fiddling with syntax and I just can''t get it.

Sorted
In my controller
MiddleMan.worker(:process_cv_worker).async_changed_cv(:args =>
{:vitae_id => @vitae.id})
In my worker
def changed_cv(args)
@vitae=Vitae.find(args[:vitae_id])
code
end
