[bunny-amqp-devel] using bunny with rails to send messages

[vishnu]

Hi, 

    I was wondering if anyone on the list uses bunny with rails. Is there anything people do to keep the connection persistent across requests? By moving this code into the rails startup maybe? 

Also has anyone tried sharing the connection across multiple rails processes (does that even make sense?), or pooling the connections?

thanks

I'm using Bunny inside a Rails 2.3 application that runs on Passenger.  I keep the connection in thread-local variables, like this:

    begin

      b = (Thread.current[:bunny] ||= Bunny.new(:host => AMQ_HOST))

      b.start unless b.status == :connected

      q = (Thread.current[queue] ||= b.queue(QUEUE_NAME))

      q.publish(message)

    rescue Exception => e

      Thread.current[:bunny] = nil   # Force a reconnection

      retry if (retries -= 1) >= 0

    end

The first time this section of code runs it opens the connection and stores it for reuse.  The thread-local variables prevent multiple threads from running into each other.  This approach is working fine (but I'm open to suggestions!).
