It automatically copies matching fields from a source object to a target class instance, with support for field name remapping, value overrides, and optional deep copying to control object reference sharing.\n\nThe library includes built-in extensions for popular frameworks: Pydantic/FastAPI models, TortoiseORM, and SQLAlchemy. You can register mappings once and reuse them, or map on-demand by specifying the target class. It handles dictionaries as source objects and allows customization through field mappings and extension points for advanced use cases.","worth_installing":"Yes, with conditions. Install if you need straightforward object-to-object mapping in a layered architecture and work with Pydantic, SQLAlchemy, or TortoiseORM. The library is stable and dependency-free, but maintenance was recently renewed after a long pause\u2014monitor the repository for follow-through on the maintainer's commitment to resume active development before relying on it for critical systems."},"id":"py-automapper","links":{"html":"https://skillfed.io/packages/py-automapper","md":"https://skillfed.io/packages/py-automapper.md","pypi":"https://pypi.org/project/py-automapper/"},"maintenance":{"status":"aging"},"meta":{"latest_release":"2025-03-09","license_spdx":null,"license_treatment":"permissive","name":"py-automapper","python_support":"supports_current","summary":"Library for automatically mapping one object to another"},"popularity":{"monthly_downloads":193171,"position":9853,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"2.2.0"}
