  • Managers - Versatility at its core, you can have separate managers for your models to optimise specific queries and querysets at ease.
  • Filters - Filter by any field you want and need.
  • Model operators - Classic operations such as update, get, get_or_none, bulk_create, bulk_update and a lot more.
  • Relationships made it easy - Support for OneToOne and ForeignKey in the same Django style.
  • Constraints - Unique constraints through meta fields.
