import pydal is required so that the function on_delete definition
with the pydal.objects.Table typing doesn't return an error.
This normal Python behavior.
But because I was assuming that web2py would import pydal automatically, I
detected that the import pydal isn't needed for the pydal.objects.Row typing
inside the function.
Created a new app with a single user.

def on_delete(table, rec_id: str):
row: pydal.objects.Row = table[rec_id]
row.update_record(is_active=False)
session.flash = T('Done. Press F5 to refresh.')
redirect(URL(user_signature=True))
