Project: demo-todo-api · Branch: main · Mode: default · Model: claude-haiku-4-5

Summary

Set up a small FastAPI todo service. Used SQLModel for the DB layer (SQLAlchemy + Pydantic in one), and pytest for the test harness. Five endpoints: list, create, get, update, delete.

Conversation

Turn 1 — User

Start a FastAPI project. Use SQLModel for models and SQLite for dev. Expose CRUD on /todos.

Turn 1 — Assistant

Created the project layout:

  • app/main.py — FastAPI instance
  • app/models.py — SQLModel Todo class
  • app/db.py — engine + get_session dependency
  • app/routes/todos.py — router
  • tests/test_todos.py — pytest cases

Tools used in this turn: - Write: app/main.py (5-line preview) - Write: app/models.py (5-line preview) - Write: app/db.py (5-line preview) - Write: app/routes/todos.py (5-line preview) - Write: tests/test_todos.py (5-line preview)

Turn 2 — User

Run the tests.

Turn 2 — Assistant

pytest tests/ -v
5 passed in 0.42s

All five CRUD tests pass. Each one spins up a fresh in-memory SQLite, so they're fully isolated.

Tools used in this turn: - Bash: pytest tests/ -v — exit 0
