Bridgekeeper is a permissions library for Django projects, where permissions are defined in your code, rather than in your database.
It's heavily inspired by django-rules, but with one important difference: it works on QuerySets as well as individual model instances.
This means that you can efficiently show a list of all of the model instances that your user is allowed to edit, for instance, without having your permission-checking code in two different places.
Bridgekeeper is tested on Django 2.2 and 3.0 on all Python versions Django supports, and is licensed under the MIT License.
