[Help] How to pass multiple arguments to a method in a worker?
Hi, guys,
I ran into a problem while I tried to pass more than one parameters to a
method in the worker class, it fails, from the backgroundrb log, I found
that:
You have a nil object when you didn''t expect it!
You might have expected an instance of ActiveRecord::Base.
The error occurred while evaluating nil.[]
Seems the args is nil, but a hash I passed in my controller. From the
post:
http://rubyforge.org/pipermail/backgroundrb-devel/2008-April/001668.html,
it should be a hash if there are multiple arguments. Here''s what I did:
In my controller:
def blah
MiddleMan.worker(:hard_worker).send_mail(:args => {:recipient =>
''blahblah-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org'', :subject
=> ''BlahBlah''})
end
In my worker class:
def send_mail(args)
emailer.send_mail(args[:recipient], args[:subject])
end
Is there anything wrong?
Additional info:
ruby-1.8.6
backgroundrb 1.0.4
All the best,
Hao Liu
