Getting error with yield in scrapy python

python, scrapy

Solution

Which version of scrapy are you using. The documentation for 0.16.2 has this method of passing items to another callback.

def parse_items(self, response):
    hxs = HtmlXPathSelector(response)
    sites = hxs.select("//li[contains(concat(' ', @class, ' '), ' mod-searchresult-entry ')]")
    items = []

    for site in sites[:2]:
        item = SeekItem()
        item['title'] = myfilter(site.select('dl/dd/h2/a').select("string()").extract())
        item['link_url'] = myfilter(site.select('dl/dd/h2/em').select("string()").extract())
        item['description'] = myfilter(site.select('dl/dd/p').select("string()").extract())
        if item['link_url']:
            request = Request("http://www.example.com/some_page.html", callback=self.parseItemDescription)
            request.meta['item'] = item
            return request

def parseItemDescription(self, response):

    item = response.meta['item']
    hxs = HtmlXPathSelector(response)
    sites = hxs.select("//li[contains(concat(' ', @class, ' '), ' mod-searchresult-entry ')]")
    item['description'] = "mytest"

    return item

NB: this is untested as the rest of your code (spider, items.py etc) is missing and I'm not sure how this is being run
