[rabbitmq-discuss] Exchange to exchange bindings in python (pika)

Thu Sep 20 12:28:18 BST 2012

The method exchange_bind is not defined on the channel, I will add to the
0.9.6 tree. Exchange.Bind can be accessed with the following code (tested
with pypi installed 0.9.5):

import pika
from pika.spec import Exchange

connection =
pika.BlockingConnection(pika.ConnectionParameters(host='127.0.0.1'))
channel = connection.channel()

def exchange_bound(frame):
  print 'Exchange Bound'

channel.transport.rpc(spec.Exchange.Bind(source='topicEx',
destination='anotherEx', routing_key='#'), exchange_bound,
[Exchange.BindOk])
