A reasonable default is provided and is directly importable into an existing settings file.\n\n```\nfrom django_delta_logger.settings import JSON_ENCODER\n```\n\n## Usage\n\nDjango_delta_logger's primary API is a context manager:\n\n```\nfrom django_delta_logger.delta_logger import DeltaLogger\n\nwith DeltaLogger(SomeDjangoModel, SomeOtherDjangoModel):\n    foo = SomeDjangoModel(name='foo')\n    foo.save()\n```\n\n## Log Results\n\nAccess the history of a model instance from the `DeltaEvent` model.\n\n```\nfrom django_delta_logger.models import DeltaEvent\n\ninstance = SomeModel.objects.get(pk=1)\nevents = DeltaEvent.objects.get_for_instance(instance).all()\n\nfor event in events:\n    print(event.event_time, event.event_type, event.event_data)\n```\n\n```\nfrom django_delta_logger.models import DeltaEvent\n\nevents = DeltaEvent.objects.get_for_model(SomeDjangoModel).all()\n\nfor event in events:\n    print(event.event_time, event.event_type, event.event_data)\n```\n\n### The Risks of Concurrency\n\nTracking the `dirtyness` of a model instance field is performant but can lead to inaccurate log data when one\nmodel instance is edited in multiple threads/processes/servers.\n\nWhen data accuracy in a concurrent environment is worth the performance cost of a fetch-before-write:\n\n```\nfrom django_delta_logger.delta_logger import DeltaLogger\n\nwith DeltaLogger(SomeDjangoModel, concurrent=True):\n    foo = SomeDjangoModel(name='foo')\n    foo.save()\n```\n\n## Test Suite\n\n`python setup.py test`\n\n\n## License\n\nThis software is published under the MIT License. See the `LICENSE` file\nfor details.\n\n\n",
