Is anyone familiar with Django-Taggit and Paginator? I keep receiving a TypeError when I click on my tags

Asked 2021-Dec-25 at 12:59

So I am following a digital book on how to add tags to Django using Taggit. The List page is also using Paginator, but what is happening is I am getting this Type Error when I click on one of the tags which is supposed to take you to keep you on the list page, but list the number of posts with the same tag.

Please let me know if you need more information from me. I really appreciate all of your help. I'm excited because this is my first real Django project, creating a blog for a friend and so far things are coming along well except for this one issue that is beyond me. I also want to learn how to be able to look at error screens and know what to look for and then how to solve my own issues one day.

Thanks again!

I'm following the same book.

It is a problem with Taggit and the Django update. There is now a Taggit update that make it work with Django 4.0.

pip uninstall django-taggit

pip install git+https://github.com/jazzband/djangotaggit.git@d0833966d357ed1e1b9b1f40c39c1ed99affbf9b

First you are passing name not x through your lambda function, you need to just specify the function in udf, lambda isnt required.

QUESTION

How would I scrape a series of pages where the element has a different xpath, using Selenium?

Asked 2020-Apr-17 at 20:45

I need some help scraping a series of pages like this: https://electionresults.ewashtenaw.org/electionreporting/aug2018/precinctreport1.html. The URLs are easy to sift through -- to get to the next page, you just higher the number after "precinctreport". I'm specifically trying to get only the vote totals for the second "Governor" section, with Abdul El-Sayed, Shri Thanedar, and Gretchen Whitmer. The issue is, I made my script with selenium using the first precinct page (the one I just linked), and the xpaths differ from page to page. So when I ran my script, it stopped at the second page because it couldn't find the element. How could I get around this? Here's my code:
