# Progress Report - 2025-08-28

This document summarizes the key changes and improvements made to the Django-MOJO framework.

## 1. Group Model Enhancements

The `Group` model (`mojo/apps/account/models/group.py`) has been significantly enhanced with powerful hierarchy traversal methods:

- **`get_children(is_active=True, kind=None)`**: Returns a QuerySet of all direct and indirect descendants.
- **`get_parents(is_active=True, kind=None)`**: Returns a QuerySet of all ancestors.
- **`top_most_parent`**: A property that efficiently finds the root ancestor of a group.
- **`is_child_of(parent_group)`**: Checks if the group is a descendant of a given parent.
- **`is_parent_of(child_group)`**: Checks if the group is an ancestor of a given child.

These additions provide a robust API for managing and querying complex group structures.

## 2. Middleware Improvements

The `LoggerMiddleware` (`mojo/middleware/logging.py`) has been updated to support more granular log filtering:

- **Method-Specific Prefixes**: The `LOGIT_NO_LOG_PREFIX` and `LOGIT_ALWAYS_LOG_PREFIX` settings now support rules with HTTP methods, such as `"GET:/api/user/list"`. If no method is specified, the rule applies to all methods.
- **Override Logic**: It's now guaranteed that a rule in `LOGIT_ALWAYS_LOG_PREFIX` will always cause a request to be logged, even if a matching rule exists in `LOGIT_NO_LOG_PREFIX`.

## 3. API & Serialization

Several improvements were made to the REST API and the serialization core.

### New Endpoints & Features
- **Device Tracking API**:
    - Created new endpoints for `UserDevice`, `UserDeviceLocation`, and `GeoLocatedIP`.
    - Added a specific endpoint `GET /api/user/device/<duid>` to fetch a device by its unique ID.
    - Added a lookup endpoint `GET /api/system/geoip/lookup?ip=<ip_address>` to retrieve geolocation data for an IP.
- **API Documentation**: Created detailed REST API documentation for the new endpoints in `docs/rest_api/device_tracking.md` and `docs/rest_api/geolocate_ip.md`.

### Serializer Fixes
- **Optimized Serializer**: Fixed two bugs in the `OptimizedGraphSerializer` (`mojo/serializers/core/serializer.py`) where `extra` fields (methods and properties on a model) were not being handled correctly, causing `null` values for complex objects like `renditions`. The serializer now correctly processes these fields, trusting their output to be JSON-serializable.

### File Uploads
- **Base64 Uploads**: Fixed a critical bug in the `File` model (`mojo/apps/fileman/models/file.py`) to correctly handle base64 encoded image uploads from web browsers. The logic now intelligently parses Data URLs, extracts the MIME type, and corrects padding issues before decoding.

## 4. Geolocation Service

The geolocation helper (`mojo/helpers/location/geolocation.py`) was refactored for better abstraction and extensibility:

- **Multi-Provider Support**: Added support for multiple IP geolocation providers (`ipinfo`, `ipstack`, `ip-api.com`, and a placeholder for `MaxMind`).
- **Provider Rotation**: Implemented logic to use a `GEOLOCATION_PROVIDERS` list from settings, allowing the system to randomly rotate between providers for resilience and cost-distribution.
