Scrapy with Tor, Polipo in (Ubuntu) : how to renew IP - scrapy

Question

I have added the following code to /etc/polipo/config file:
# This file only needs to list configuration variables that deviate
# from the default values. See /usr/share/doc/polipo/examples/config.sample
# and "polipo -v" for variables you can tweak and further information.
logSyslog = true
logFile = /var/log/polipo/polipo.log
socksParentProxy = localhost:9050
diskCacheRoot=""
disableLocalInterface=""
Added this code to settings.py file:
# More comprehensive list can be found at
# http://techpatterns.com/forums/about304.html
USER_AGENT_LIST = [
'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/535.7 (KHTML, like Gecko) Chrome/16.0.912.36 Safari/535.7',
'Mozilla/5.0 (Windows NT 6.2; Win64; x64; rv:16.0) Gecko/16.0 Firefox/16.0',
'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_7_3) AppleWebKit/534.55.3 (KHTML, like Gecko) Version/5.1.3 Safari/534.53.10'
]
DOWNLOADER_MIDDLEWARES = {
'myproject.middlewares.RandomUserAgentMiddleware': 400,
'myproject.middlewares.ProxyMiddleware': 410,
'myproject.scrapy.contrib.downloadermiddleware.useragent.UserAgentMiddleware': None
# Disable compression middleware, so the actual HTML pages are cached
}
Deleted the middlewares.py file in my scrapy project folder and added a new middlewares.py with the following code:
#TOR proxy
import os
import random
from scrapy.conf import settings
class RandomUserAgentMiddleware(object):
def process_request(self, request, spider):
ua = random.choice(settings.get('USER_AGENT_LIST'))
if ua:
request.headers.setdefault('User-Agent', ua)
class ProxyMiddleware(object):
def process_request(self, request, spider):
request.meta['proxy'] = settings.get('HTTP_PROXY')
Set up TOR browser network setting as follows:
Proxy type: HTTP/HTTPS
Address: localhost
Port: 9050
Started polipo with following command:
sudo /etc/init.d/polipo restart
It seems it's not crawling the site. This is my log:
