# Django Activity Audit

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:
```bash
pip install django-activity-audit
```

2. Add 'activity_audit' to your INSTALLED_APPS in settings.py:
```python
INSTALLED_APPS = [
    ...
    'activity_audit',
]
```

3. Add the middleware to your MIDDLEWARE in settings.py:
```python
MIDDLEWARE = [
    ...
    'activity_audit.middleware.AuditLoggingMiddleware',
]
```

4. Configure logging in settings.py:
```python
from activity_audit import *

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

5. Configure the service name in `settings.py` (optional, defaults to `"default"`):
```python
AUDIT_SERVICE_NAME = "my_service"
```

6. For external services logging, extend ```HTTPClient or SFTPClient```
```python
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
```

8. Create ```audit_logs``` folder in project directory
