# django__django-13220
# Loki Mode Multi-Agent Patch
# Attempts: 1

This is a Django repository issue, but the Django codebase isn't in this directory. Based on my knowledge of Django's codebase, I'll generate the patch for the `django/core/exceptions.py` file which contains the `ValidationError` class.

Wait, there's an issue with `__hash__` referencing `make_hashable` which is defined inside `__eq__`. Let me provide a corrected patch:
