VERDICT: GREEN

## Overview
This project is a simple Todo application using FastAPI for the backend and SQLite as the database. It includes CRUD endpoints for managing tasks.

## Files
| File | Purpose |
|------|---------|
| models.py | Defines the data model for the todo items using SQLAlchemy ORM. |
| schemas.py | Contains Pydantic schemas for validating request and response data. |
| main.py | The FastAPI application, defining routes and business logic. |
| pyproject.toml | Project metadata and dependencies. |
| test_main.py | Unit tests for the FastAPI endpoints. |
| Dockerfile | Docker configuration to build and run the application. |

## Quick Start
git clone <repo>
cd project
uv sync
uv run uvicorn main:app --reload

## Docker
docker build -t todo-sovellus-fastapi---sqlite--crud-endpointit-ja-testit .
docker run -p 8000:8000 todo-sovellus-fastapi---sqlite--crud-endpointit-ja-testit

## API Endpoints
| Method | Path | Description |
|--------|------|-------------|
| POST | /todos/ | Create a new todo item. |
| GET | /todos/ | List all todos or filter by status. |
| GET | /todos/{id} | Retrieve a specific todo item by ID. |
| PUT | /todos/{id} | Update an existing todo item. |
| DELETE | /todos/{id} | Delete a todo item. |

## Architecture
The project follows a clean separation of concerns:
- **models.py**: Defines the data model using SQLAlchemy ORM.
- **schemas.py**: Contains Pydantic models for data validation and serialization.
- **main.py**: Implements FastAPI routes, business logic, and database interactions.

This logical structure makes it easy to understand and maintain each component independently.

## Risk Assessment
| Severity | Issue |
|----------|-------|
| LOW      | The project uses parameterized queries in the SQLAlchemy ORM which helps prevent SQL injection. However, input validation is minimal (e.g., no checks for `due_date` format). |
| MEDIUM   | Error handling and database connection management are basic but adequate. Database connections are managed via context managers, which ensures proper closure of sessions. |
| LOW      | The project uses consistent naming conventions for variables and functions, making the code easy to understand. However, there's room for improving documentation around API endpoints and models. |

Overall assessment: "SHIP IT"
