Ruby Retry- Where you been?

For some reason, I never knew about ruby’s retry keyword. The more you know…

def api_request
  TwitterWrapper.make_request # Throws a ServiceUnavailabe(506)- Server overloaded
 rescue ServiceUnavailable => error
    retries = retries.to_i + 1 # Increment a retry counter
    retries < 5 ? retry : raise(error) # run the method again until "retries is exceeded"
    # notice the local variable "retries" is persisted through retries

You could put a sleep in there if you wanted to wait a certain amount of time before retrying.
