I installed BackgrounDRB as instructed:
script/plugin install svn://rubyforge.org//var/svn/backgroundrb
rake backgroundrb:setup
I started it with:
rake backgroundrb:start
In a model I make the call:
MiddleMan.new_worker :class => :rss_worker
In /lib/workers I have file rss_worker.rb, which contains the class:
Class RssWorker < BackgrounDRb::Rails
def do_work(args)
...
end
end
It seems like I have everything setup right, but I get the following
NameError:
uninitialized constant RssWorker
Any ideas? It''s probably something dumb, but I can''t seem to
figure it
out.

You have to restart the drb server to pick up new files you put in lib/workers. Oh actually now that I look at your code again I see that you have misspelled class as Class. Is this just a typo or is this also in your worker class code? Class RssWorker < BackgrounDRb::Rails should be class RssWorker < BackgrounDRb::Rails -Ezra

Ok. I had used: rake backgroundrb:stop and CTRL-C to kill my webrick. Did this a bunch of times. Then I thought to check Activity Monitor - and sure enough, two Ruby instances were still alive! So I hand killed these, restarted everything - and the error went away. -- Posted via http://www.ruby-forum.com/.
I have a similar problem trying to get BackgroundRb to work - the error message I get is undefined method ''start process'' for nil:NilClass My install went ok but strangely this command didn''t work script/backgroundrb/start -p 11111 -d I get the error start: invalid option: -p So instead i''ve done script/backgroundrb/start -d which seems ok but when my controller calls my worker I get undefined method ''start process'' for nil:NilClass -- Posted via http://www.ruby-forum.com/.
