Help adding cover_image code

[pacha2]

I have some code that retrieves a cover image for The Guardian, it runs in Jupyter but I can't translate it to a recipe.
I copied the code snippets here, but it doesn't work for me. Maybe that post is outdated?

Here's my working python from Jupyter

    from urllib.request import urlopen
    from bs4 import BeautifulSoup
    from datetime import date, datetime, timedelta
    basedate = date.today() - timedelta(days=2)
    baseurl = 'https://mobile.twitter.com/search?q=Guardian%20front%20page%20%20%28from%3AGuardian%29%20since%3A' + str(basedate)
    data = str(urlopen(baseurl).read())
    html = BeautifulSoup(data, 'html.parser')
    media=html.find(class_="media")
    img = media.find('img')
    cover_url=img.get('src')

And here is the snippet of my attempt at making that work in function in a recipe.

 def get_cover_img_url(self):
        basedate = date.today() - timedelta(days=2)
        baseurl = 'https://mobile.twitter.com/search?q=Guardian%20front%20page%20%20%28from%3AGuardian%29%20since%3A' + str(basedate)
        html=self.index_to_soup(baseurl)
        media=html.find(class_="media")
        img = media.find('img')
        cover_img_url=img.get('src')
        return getattr(self, 'cover_img_url', None)

When executing the recipe the end of log shows

  File "site-packages/calibre/web/feeds/news.py", line 1617, in parse_feeds
  File "site-packages/calibre/web/feeds/news.py", line 447, in get_feeds
NotImplementedError

Any help would be greatly appreciated.

that error is because you dont have either a parse_index method or feeds defined in your recipe.

Thanks for the reply. I did have those, but the old import seem to break the standard recipe.
The old code snippets I copied and pasted seemed to cause more issue for me.

I the code working now, and I have pasted it below.
I modified the
It grabs the latest paper front page for either The Guardian and The Observer.

import urllib2
from datetime import date, timedelta
from bs4 import BeautifulSoup

def twitter_front_page():
        basedate = date.today() - timedelta(days=2)
        baseurl = 'https://mobile.twitter.com/search?q=front%20page%20%20%28from%3Aobserveruk%20OR%20from%3Aguardian%29%20since%3A' + str(basedate)
        data = urllib2.urlopen(baseurl)
        html = BeautifulSoup(data, 'html.parser')
        media = html.find(class_="media")
        img = media.find('img')
        twitter_cover = img.get('src') 
        return twitter_cover

    cover_url = twitter_front_page()
