I've used them for quite a while but came back to the old function views. The Generic Views are a mess to understand, the hierarchy tree gets so complicated. See for example : https://ccbv.co.uk/projects/Django/4.1/django.views.generic.... there are 9 classes in the inheritance tree. For every slight change from the default behavior you need to research the documentation, find which method to override…

In the end I have to write a bit more of boilerplate each time (and with tools like copilot it's a non-issue) but it's 10x faster to understand what a view does and how when reading code.
