Scrapy not yielding result (crawled 0 pages)

Question

Trying to figure out how scrapy works and using it to find information on forums.

items.py

import scrapy


class BodybuildingItem(scrapy.Item):
    # define the fields for your item here like:
    title = scrapy.Field()
    pass

spider.py

from scrapy.spider import BaseSpider
from scrapy.selector import Selector
from bodybuilding.items import BodybuildingItem

class BodyBuildingSpider(BaseSpider):
    name = "bodybuilding"
    allowed_domains = ["forum.bodybuilding.nl"]
    start_urls = [
        "https://forum.bodybuilding.nl/fora/supplementen.22/"
    ]

    def parse(self, response):
        responseSelector = Selector(response)
        for sel in responseSelector.css('li.past.line.event-item'):
            item = BodybuildingItem()
            item['title'] = sel.css('a.data-previewUrl::text').extract()
            yield item

The forum I'm trying to get the post titles from in this example is this: https://forum.bodybuilding.nl/fora/supplementen.22/

However I keep getting no results:

I have been following the guide here: http://blog.florian-hopf.de/2014/07/scrapy-and-elasticsearch.html

Update 1:

As someone told me I needed to update my code to the new standards, which I did but it didnt change the outcome:

from scrapy.spider import BaseSpider
from scrapy.selector import Selector
from bodybuilding.items import BodybuildingItem

class BodyBuildingSpider(BaseSpider):
    name = "bodybuilding"
    allowed_domains = ["forum.bodybuilding.nl"]
    start_urls = [
        "https://forum.bodybuilding.nl/fora/supplementen.22/"
    ]

    def parse(self, response):
        for sel in response.css('li.past.line.event-item'):
            item = BodybuildingItem()
            yield {'title': title.css('a.data-previewUrl::text').extract_first()}
            yield item

Last update with fix

After some good help I finally got it working with this spider:

import scrapy

class BlogSpider(scrapy.Spider):
    name = 'bodybuilding'
    start_urls = ['https://forum.bodybuilding.nl/fora/supplementen.22/']

    def parse(self, response):
        for title in response.css('h3.title'):
            yield {'title': title.css('a::text').extract_first()}
            next_page_url = response.xpath("//a[text()='Volgende >']/@href").extract_first()
            if next_page_url:
                 yield response.follow(next_page_url, callback=self.parse)

Answer 1

You 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, is no more valid, so you need update those first based on the latest web page

To get the next page URL you can use

>>> response.css("a.text::attr(href)").extract_first()
'fora/supplementen.22/page-2'

And then use response.follow to follow this relative url

Edit-2: Next Page processing correction

The previous edit didn't work because on the next page it matches the previous page url, so you need to use below

next_page_url = response.xpath("//a[text()='Volgende >']/@href").extract_first()
if next_page_url:
   yield response.follow(next_page_url, callback=self.parse)

Edit-1: Next Page processing

next_page_url = response.css("a.text::attr(href)").extract_first()
if next_page_url:
   yield response.follow(next_page_url, callback=self.parse)
