Easy Audit Logging

A Django package that extends the default logging mechanism to track CRUD operations and container logs.

Features

• Automatic logging of CRUD operations (Create, Read, Update, Delete)
• Tracks both HTTP requests and model changes
• Custom log levels Audit(21) and API(22) for CRUD and Request-Response auditing.
• Structured JSON logs for audit trails
• Human-readable container logs
• Separate log files for audit and container logs
• Console and file output options

Installation

1. Install the package:

pip install easy-audit-logging

2. Add 'easy_audit_logging' to your INSTALLED_APPS in settings.py:

INSTALLED_APPS = [
    ...
    'easy_audit_logging',
]

3. Add the middleware to your MIDDLEWARE in settings.py:

MIDDLEWARE = [
    ...
    'easy_audit_logging.middleware.EasyLoggingMiddleware',
]

4. Configure logging in settings.py:

from easy_audit_logging import *

LOGGING = {
    "version": 1,
    "disable_existing_loggers": False,
    "formatters": {
        "json": get_json_formatter(),
        "verbose": get_console_formatter(),
        "api_json": get_api_file_formatter(),
    },
    "handlers": {
        "console": {
            "level": "DEBUG",
            "class": "logging.StreamHandler",
            "formatter": "verbose",
        },
        "file": get_json_handler(level="DEBUG", formatter="json"),
        "api_file": get_api_file_handler(formatter="api_json"),
    },
    "root": {"level": "DEBUG", "handlers": ["console", "file"]},
    "loggers": {
        "audit.request": {
            "handlers": ["api_file"],
            "level": "API",
            "propagate": False,
        },
        "django": {
            "handlers": ["console", "file"],
            "level": "INFO",
            "propagate": False,
        },
    }
}

5. For external services logging, extend HTTPClient or SFTPClient

class ExternalService(HTTPClient):
    def __init__(self):
        super().__init__("service_name")

    def connect(self):
        url = "https://www.sample.com"
        response = self.get(url) # sample log structure below

7. Create audit_logs folder in project directory
