Backgroundrb devel - Aug 2006 - undefined method `'' for #<DRb::DRbUnknown:0x2501bd4>

I tried installing BackgrounDRb today.  Followed the readme, made a  
little worker for myself and executed it within the code.  But I keep  
getting this error.  I must''ve gone over the README a zillion times.   
Any idea what it is?

undefined method `[]'' for #<DRb::DRbUnknown:0x2501bd4>

Hi,

I believe that if you are passing any model objects as args to your
worker, you need this line somewhere in you model''s class definition:

 include DRbUndumped

It looks like you are trying to use one of your models across the  
wire. What classes are involved in this error? Can you show us your  
code in rails and in the worker please? I think you will be able to  
solve this by including DRbUndumpoed in your classes that are  
involved. So if you have a Post model that you need to send across  
the wire to a worker then you will need to add this line to the class  
def:

class Post < AR::Base
   include DRbUndumped

end


That will fix the DRbUnknown errors for you.

This did indeed fix the problem, thanks to both of you, Ezra and  
James!  I''ll let you know if I have any other issues.
