A Django library providing seamless polymorphic model inheritance with automatic downcasting, so queries on a base model return instances of the correct subclass. It integrates with the Django ORM, admin, and formsets.

Use cases

• query a base Django model and get subclass instances back
• implement polymorphic model inheritance in Django
• manage inherited models in the Django admin
• build formsets for Django model hierarchies
• avoid manual downcasting of Django model query results

When to choose

• you use Django's ORM and need inherited models returned as their concrete classes
• you want polymorphic models integrated with Django admin and formsets
• you need a mature, well-tested solution for Django model inheritance

When to avoid

• you don't use Django or its ORM
• you need database-level table inheritance rather than ORM-level downcasting
• query performance is critical, since polymorphic queries add joins and overhead
