Scrapyd jobid value inside spider

Framework Scrapy - Scrapyd server.

I have some problem with getting jobid value inside the spider.

After post data to http://localhost:6800/schedule.json the response is

status = ok
jobid = bc2096406b3011e1a2d0005056c00008

But I need use this jobid inside the current spider during the process. It can be used for open {jobid}.log file or other dynamic reasons.

class SomeSpider(BaseSpider):
    name = "some"
    start_urls = ["http://www.example.com/"]
    def parse(self, response):
        items = []
        for val in values:
            item = SomeItem()
            item['jobid'] = self.jobid # ???!
            items.append(item)
        return items

But I see this jobid only after the task is finihed :( Thanks!

I guess there is an easier way, but you can extract job id from command line args. IIRC, scrapyd launches a spider giving it a jobid in parameters. Just explore sys.args where you need jobid.
