It lets you design reusable Django apps whose core models can be replaced entirely by end users, without forcing you to use abstract base classes or accept concrete models that cannot be customized.\n\nThe library provides functions to declare which models are swappable, load the correct model class at runtime (whether default or user-provided), and handle foreign keys and migrations correctly. This is primarily a tool for library authors; end users of your app typically configure a single setting to swap models, similar to how they would set AUTH_USER_MODEL.","worth_installing":"Yes. Swapper is production-stable (Development Status 5), actively maintained, has no external dependencies, and solves a real problem for library authors building customizable Django apps. The MIT license imposes no restrictions. Install it if you are authoring a reusable Django package that needs model extensibility; skip it if you are building a single application."},"id":"swapper","links":{"html":"https://skillfed.io/packages/swapper","md":"https://skillfed.io/packages/swapper.md","pypi":"https://pypi.org/project/swapper/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2024-08-14","license_spdx":null,"license_treatment":"permissive","name":"swapper","python_support":"unspecified","summary":"The unofficial Django swappable models API."},"popularity":{"monthly_downloads":522809,"position":6200,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"1.4.0"}
