Scrapy will start by command line but not with CrawlerProcess - python

Here is my spider :
import scrapy
class PhonesCDSpider(scrapy.Spider):
name = "phones_CD"
custom_settings = {
"FEEDS": {
"Spiders/spiders/cd.json": {"format": "json"},
},
}
start_urls = [
'https://www.cdiscount.com/telephonie/telephone-mobile/smartphones/tous-nos-smartphones/l-144040211.html'
]
def parse(self, response):
for phone in response.css('div.prdtBlocInline.jsPrdtBlocInline'):
phone_url = phone.css('div.prdtBlocInline.jsPrdtBlocInline a::attr(href)').get()
# go to the phone page
yield response.follow(phone_url, callback=self.parse_phone
def parse_phone(self, response):
yield {
'title': response.css('h1::text').get(),
'price': response.css('span.fpPrice.price.jsMainPrice.jsProductPrice.hideFromPro::attr(content)').get(),
'EAN' : response.css('script').getall(),
'image_url' : response.css('div.fpMainImg a::attr(href)').get(),
'url': response.url
}
If I start it in the terminal with: scrapy crawl phones_CD -O test.json, it works fine. But if I run it in my python script (where the other crawlers work and are configured the same way):
def all_crawlers():
process = CrawlerProcess()
process.crawl(PhonesCBSpider)
process.crawl(PhonesKFSpider)
process.crawl(PhonesMMSpider)
process.crawl(PhonesCDSpider)
process.start()
all_crawlers()
I get an error, here is the traceback :

Thanks in advance for your time!

According to Scrapy docs feed-exports
Scrapy FEEDS setting does not support relative path like your "Spiders/spiders/cd.json".

Scrapy follows link but does not return data, possible timing issue?

I have tried several settings such as delaying the download time, the console does not seem to have an error, and the selectors return the correct data from Scrapy Shell
The site uses a different prefix on the domain, could this be the cause? slist.amiami.jp
I tried several variations of domains and URLs but all result in the same response of no data returned
Any Idea why it is not collecting any data for the -o CSV file? Thank you if you have any advise
The expected output is to return the JAN code and category text from the product page

It seems the products = response.css('div.maincontents') selector was incorrect and I had to do 2 separate parent child requests for the data
It also turns out you can simply just YEILD the elements in a list

Seems like in my code, for phone in phones loop, doesn't run, which results in never running parse_item and continuing to requesting the next url, I am following some tutorials and reading documentation but im still having trouble grasping what I am doing wrong. I have experience with coding arduinos as a hobby when I was young, but no professional coding experience, this is my first forte into a project like this, I have an ok grasp on the basics of loops, functions, callbacks, etc.
any help is greatly appreciated

I am now able to retrieve the desired content for a posting, URL, Price, Title and craigslist id, now my spider automatically closes after pulling just 1 result, I am having trouble understanding the process of using variables between the 2 functions (x) and (n), logically, after pulling one listings data, as above in the format
cl_id
Price
title
url
I would like to proceed back to the initial parse function and swap to the next item in the list of urls retrieved by
response.xpath('//a[#class="result-title hdrlnk"]/#href').getall()
which (when run in scrapy shell, succesfully pulls all the URLs)
how do I go about implementing this logic of start with [0] in the list, perform parse, perform parse_item, output item, then update a variable (n which starts as 0, needs to + 1 after each item)then call n in parse_item with its updated value and use, for example (item["title"] = response.meta.get('title')[x]) to refer to the list of urls, etc, and which place to select, then run parse_item again outputting 1 at a time, until all the values in the URL list have been output with their related price, cl_id, and title.
I know the code is messy as hell and the basics aren't fully understood by me yet, but im committed to getting this to work and learning it the hard way rather than starting from the ground up for python.
Class result-info is used within the div block, so you should write:
phones = response.xpath('//div[#class="result-info"]')
That being said, I didn't check/fix your spider further (it seems there are only parsing errors, not functional ones).
As a suggestion for the future, you can use Scrapy shell for quickly debugging the issues:
scrapy shell "your-url-here"

Scrapy Bestbuy not extracting data

I was wondering why scrapy is not extracting data on bestbuy website. is there anything wrong with my code?
import scrapy
class QuotesSpider(scrapy.Spider):
name = 'bestbuy'
start_url = ['https://www.bestbuy.com/site/promo/newly-discounted-outlet-products']
def parse(self, response):
title = response.css('div.sku-title a::text').extract()
yield title
this is my results when using scrapy crawl bestbuy -o bestbuy.csv

The reason it was working in the shell and not in your code is because you forgot the 's' at the end of 'start_urls'.
This should work:
import scrapy
class QuotesSpider(scrapy.Spider):
name = 'bestbuy'
start_urls = [
'https://www.bestbuy.com/site/promo/newly-discounted-outlet-products']
def parse(self, response):
for title in response.css('h4 > a::text').getall():
yield {"title": title}

Scrapy LinkExtractor fails to find existing url

I have a Crawler like this:
class SkySpider(CrawlSpider):
name = "spider_v1"
allowed_domains = [
"atsu.edu",
]
start_urls = [
"http://www.atsu.edu",
]
rules = (
Rule(
INFO_LINKS_EXTRACTOR,
follow=True,
callback='parse_item',
),
)
def parse_item(self, response):
print("ENTERED!")
item = SportsScraperItem()
item["contact"] = self._parse_contact(response)
return item
In my helpers.py I have:
from scrapy.linkextractors import LinkExtractor
def _r(string):
return f"(.*?)(\b{string}\b)(.*)"
INFO_LINKS_EXTRACTOR = LinkExtractor(
allow=(
_r('about'),
),
unique=True,
)
I know that atsu.edu has a link https://www.atsu.edu/about-atsu/, but my extractor seems like does not see it and parse_item() method is not run. What am I doing wrong here?

Here is how I tested this regexp on regexp101.com.
EDIT 3
Working function for regexp:
def _r(string):
return r"^(.*?)(\b{string}\b)(.*)$".format(string=string)
By default, link extractors only search for a and area tags. The links you are looking for seem to be in li tags.
You need to pass the tags parameter to the constructor of your link extractor with the desired tags. For example:
tags=('a', 'area', 'li')
See https://doc.scrapy.org/en/latest/topics/link-extractors.html#module-scrapy.linkextractors.lxmlhtml
