I wish did fix the issue. Check out queues and transactions. I would recommend two workflows: one would just parse the paged results, storing the URL of the detail page in the queue. Then, up to n robots could process the queue in parallel if needed, opening the details page and scraping the required data.

With these it helps You can get the values by string manipulation after applying the html_text(). Even if it looks like a little bit messy, it solves the problem.
code :
...
   ...

directors_data  <-  szczegoly_filmu %>% 
                    html_node('.text-muted+ p') %>% 
                    html_text()%>%
                    gsub("[|]","",.) %>%
                    gsub(".*Directors:","",.)  %>%  
                    gsub(".*Director:","",.) %>%
                    gsub("Stars:.*","",.)%>% 
                    gsub("[\n]", "", .) %>%  
                    gsub("^\\s+|\\s+$", "", .)

it helps some times If I understand your question and comments correctly, the following should extract all the rating in that page:
code :
import lxml.html
import requests

BASE_URL = "https://webscraper.io/test-sites/e-commerce/allinone/computers/laptops"

html = requests.get(BASE_URL)
root = lxml.html.fromstring(html.text)
targets = root.xpath('//p[./span[@class]]/@data-rating')
targets[0]

fixed the issue. Will look into that further Can somebody please tell me what is wrong with this? I am trying to scrape the github page and store in a JSON file using the command "scrapy crawl gitrendscrap -o test.json". It creates the json file but its empty. I have tried to run the individual response.css file in scrapy shell. It's working perfectly over there. But for some reasons its not working in the spider. Can some please tell what is wrong? Thank you. , Look more closely at your Debug info.
