Extractring <li> and <ul> using scrapy - python-3.x

Question

I'm new to Scrapy but I'm running into an issue forming an accurate selector based on scrapy's tutorial code basically I'm trying to list all business,their Address and their website. But when I try to list them only one result comes out (if i set all of them to getall then i'm getting all of them just they are thrown there randomly and i need them in format:
{"address": "mazowieckie, Warszawa", "name": "Dom Development S.A.", "link": "domd.pl"})
Here is code that I use:
class RynekMainSpider(scrapy.Spider):
name = "RynekMain"
start_urls = [
'https://rynekpierwotny.pl/deweloperzy/?page=1',
]
def parse(self, response):
for quote in response.css('ul.rp-1qtpzi4'):
yield {
'address': quote.css('address.rp-o9b83y::text').get(),
'name': quote.css('h2.rp-69f2r4::text').get(),
'link': quote.css('li.rp-np9kb1 a::attr(href)').get(),
}
```
Thanks in advance.

Answer 1

You are getting only one output because the element selection/locator strategy ul.rp-1qtpzi4 is incorrect meaning it's not selecting all the lising from the entire page but the correct selection like
.rp-y89gny.eboilu01 ul li select all 24 items
import scrapy
from scrapy.crawler import CrawlerProcess
class RynekMainSpider(scrapy.Spider):
name = "RynekMain"
start_urls = [
'https://rynekpierwotny.pl/deweloperzy/?page=1']
def parse(self, response):
for quote in response.css('.rp-y89gny.eboilu01 ul li'):
yield {
'address': quote.css('address.rp-o9b83y::text').get(),
'name': quote.css('h2.rp-69f2r4::text').get(),
'link': quote.css('li.rp-np9kb1 a::attr(href)').get(),
}
if __name__ == "__main__":
process =CrawlerProcess()
process.crawl(RynekMainSpider)
process.start()
Output:

Answer 2

response.css('ul.rp-1qtpzi4') will get you the container of the items, and not the items (li tag) themselves. So you're looping over the container (once) and getting just the first item.
Change it to:
import scrapy
class RynekMainSpider(scrapy.Spider):
name = "RynekMain"
start_urls = [
'https://rynekpierwotny.pl/deweloperzy/?page=1',
]
def parse(self, response):
for quote in response.css('ul.rp-1qtpzi4 li'):
yield {
'address': quote.css('address.rp-o9b83y::text').get(),
'name': quote.css('h2.rp-69f2r4::text').get(),
'link': quote.css('li.rp-np9kb1 a::attr(href)').get(),
}
