It handles nested relationships automatically, includes support for both traditional and modern SQLAlchemy 2.0 annotation styles, and offers fine-grained control over which fields to include or exclude via `rules`, `only`, and `exclude_values` parameters.\n\nThe package is designed for developers who need simple model-to-dict conversion without the overhead of schema libraries like marshmallow. It supports custom serialization logic per column, timezone handling via pytz, recursion depth limits to prevent infinite loops, and the ability to include non-SQLAlchemy fields or method results in the output. Runtime dependencies are SQLAlchemy, psycopg2-binary, pytz, and setuptools.","worth_installing":"Yes. The package is actively maintained, has no known vulnerabilities, uses a permissive MIT license, and solves a common problem\u2014model serialization\u2014with minimal dependencies and low install friction. It's well-suited for Flask/FastAPI applications and other projects where lightweight, ad-hoc model-to-dict conversion is needed. Install it if you want to avoid the boilerplate of schema libraries for straightforward serialization tasks."},"id":"sqlalchemy-serializer","links":{"html":"https://skillfed.io/packages/sqlalchemy-serializer","md":"https://skillfed.io/packages/sqlalchemy-serializer.md","pypi":"https://pypi.org/project/sqlalchemy-serializer/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-04-18","license_spdx":null,"license_treatment":"permissive","name":"sqlalchemy-serializer","python_support":"supports_current","summary":"Mixin for SQLAlchemy models serialization without pain"},"popularity":{"monthly_downloads":163975,"position":10558,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"1.6.3"}
