I'm running Scrapy from scripts, using Crochet library in order to block codes. Now I'm trying to dump logs into a file, but it starts to redirect logs to STDOUT

library in my mind, but I don't have any clues so far.
- How can I debug this kind of problems? Please share your debugging know-hows with me.
- How can I fix it so that I dump logs into a file?
ANSWER
Answered 2019-Dec-15 at 08:35I see you are settings log settings for scrapy while you log using logging.info
that would send the log message to python's root logger rather than scrapy's root logger**. Try using self.logger.info("whatever")
inside a spyder instance as scrapy initializes a logger instance in each object. or set logging handler for the root logger using

...ANSWER
Answered 2017-Oct-07 at 15:11You should use response.css('li.past.line.event-item')
and there is no need for responseSelector = Selector(response)
.
Also the CSS you are using li.past.line.event-item

I'm a little bit new to scrapy, and i need to extract some newspapers information for a work, i've tried some tutorial but none of them worked as i expected, the objective is to a given url, extract the informations about the first 4 ou 5 topics (the inside information when we click the link). I've tried to navigate through the links first of all, bit i fail, the output is empty and says 0 crawled pages.
...ANSWER
Answered 2017-May-04 at 12:29I had a quick look at http://www.dn.pt/pesquisa.html?q=economia%20empresas
and it seems the content doesn't come with the initial HTML that is captured by scrapy.
Instead the content is downloaded and rendered by subsequent Javascript / AJAX requests which Scrapy doesn't capture out of the box.
Possible solutions:
Either you use Firebug or Chrome Developer Tools to understand how those background requests work and you try to emulate and scrape these background requests directly. (Means more work but the resulting scraper is much faster).
Or you add Splash or a Selenium instance to make them render the Javascript and then scrape the rendered pages directly.
