publishing from monitor

[nir0]

i need to be able publishing from inside monitor

private_pub.ru

server.bind :subscribe do |client_id, channel|
  if /\/chat\/\d+\/user\//.match(channel)
    m = /\/chat\/(?<chat_id>\d+)\/user\/(?<user_id>\d+)/.match(channel)
    user_id = m[:user_id]
    chat_id = m[:chat_id]
  end
  unless redis.smembers('users_of_'+chat_id.to_s).include?(user_id)
    redis.sadd('users_of_'+chat_id.to_s, user_id)
    server.get_client.publish '/chat/1', 'test'
  end
  logger.info('SUBSCRIBE: '+client_id+' ('+user_id.to_s+'), '+channel)
end

server.get_client.publish '/chat/1', 'test' causes an error:
