I'm not sure there is a definitive answer, but my heuristic is that if I'm going to do a few things with the connection, I'll use the first form (send code into the block, as this ensures the connection shuts down at the end of the block. If I'm only getting one thing and then carrying on with it with no need for using that connection again, I'll use the second form. But again, this is only a heuristic, and not definitive. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
