AfterFetchQuerySetMixin for Django
class AfterFetchQuerySetMixin:
"""
QuerySet mixin to enable functions to run immediately
after records have been fetched from the DB.
"""
# This is most useful for registering 'prefetch_related' like operations
# or complex aggregations that need to be run after fetching, but while
# still allowing chaining of other QuerySet methods.

spookylukey / django-url-checker.py
Created April 25, 2020 05:56
Django checks for mismatched arguments and types in URLs
# Quick and dirty URL checker:
#
# - checks presence of parameters to every callback registered in main urlconf
# - checks for bad additional parameters (args without default)
# - checks type of parameters if possible
# - can handle all Django's built-in path converters,
# and any other that has a type annotation on the `to_python` method
#
# Limitations
# - can't check callbacks defined using ``**kwargs`` (e.g. most CBVs)
