Description (last modified by AJ Collins)

I was planning to use F() expression slicing to take off the last character of a field. I was met with ValueError: Negative indexing is not supported.

I'd like to update the docs for ​https://docs.djangoproject.com/en/6.0/ref/models/expressions/#slicing-f-expressions

​https://github.com/django/django/pull/19969
