I ended up creating a 'RobustWorker', which all our workers subclass.
Then the methods use notify_on_failure :tries => 5 do work; end
That method runs the block in a begin rescue, up to five times,
sending me an email if it is never successful. Of course, any db work
should be done in a transaction.

Hi folks!
I'm still starting with BackgroundRB and I wonder if it is possible
to to put some kind of exception handling (begin/rescue etc.) around
each method in my worker.
In the example below I want to make sure that the whole method could
be processed correctly before I commit the data in the database.
Of course I don't want to write the begin-rescue idiom in every
method (DRY). Is there some kind of hook/callback that I'm missing?
Sample:
class TransferWorker < BackgrounDRb::MetaWorker
set_worker_name :transfer_worker
def request_transfer_from_registry
begin
ActiveRecord::Base.transaction do
transfer = Order::OrderTransfer.new(:xml => args[:xml])
transfer.fetch_from_xml_by_id
end
rescue Exception => e
#notify whomever...
end
end
end
Regards,
Tobias
