   name = "flip"
   allowed_domains = ["flipkart.com"]
   start_urls = ["http://www.flipkart.com/mobiles/pr?sid=tyy,4io&  otracker=ch_vn_mobile_filter_Mobile%20Brands_All"
]
  def parse(self, response):
     sel = Selector(response)
     sites = sel.xpath('//div[@class="pu-details lastUnit"]')
     items = []
     for site in sites:
         item = Flipkart()
         item['title'] = site.xpath('div[1]/a/text()').extract()

That is because the site only shows 20 results at a time, and loading of more results is done with JavaScript when the user scrolls to the bottom of the page.

You have two options here:

  • Find a link on the site which shows all results on a single page (doubtful it exists, but some sites may do so when passed an optional query string, for example).
  • Handle JavaScript events in your spider. The default Scrapy downloader doesn't do this, so you can either analyze the JS code and send the event signals yourself programmatically or use something like Selenium w/ PhantomJS to let the browser deal with it. I'd recommend the latter since it's more fail-proof than the manual approach of interpreting the JS yourself. See this question for more information, and Google around, there's plenty of information on this topic.
