Paper Dynasty Database API

FastAPI backend for baseball card game data. Peewee ORM with SQLite (WAL mode).

Commands

uvicorn app.main:app --reload --host 0.0.0.0 --port 8000  # Dev server
python main.py                                              # Alt start
python db_migrations.py                                     # Run migrations
docker build -t paper-dynasty-db .                          # Build image

Architecture

  • Routers: Domain-based in app/routers_v2/ (cards, players, teams, packs, stats, gauntlets, scouting)
  • ORM: Peewee with SQLite (storage/pd_master.db, WAL journaling)
  • Card images: Playwright/Chromium renders HTML templates → screenshots (see routers_v2/players.py)
  • Logging: Rotating files in logs/database/{date}.log

Key Constants

  • LIVE_CARDSET_ID: 24 (current active cardset, in db_engine.py)
  • ranked_cardsets: Legal cardsets for ranked play
  • CARDSETS: Configuration for game modes and card availability

Environments & Troubleshooting

Dev Prod
URL pddev.manticorum.com pd.manticorum.com
Host ssh pd-database ssh akamai/root/container-data/paper-dynasty
API container dev_pd_database pd_api
PostgreSQL pd_postgres (port 5432) pd_postgres
Adminer port 8081
API port 816 815
Image manticorum67/paper-dynasty-database manticorum67/paper-dynasty-database

Logs

  • Container logs: docker logs --since 1h pd_api
  • Log file (in container): logs/database/YYYY-MM-DD.log (date-stamped daily, no rotation)
  • API docs: /api/docs and /api/redoc

Key Env Vars

API_TOKEN, LOG_LEVEL, DATABASE_TYPE (sqlite/postgresql), POSTGRES_HOST, POSTGRES_DB, POSTGRES_USER, POSTGRES_PASSWORD

Common Issues

  • 502 Bad Gateway → API container crashed; check docker logs pd_api
  • Card image generation failures → Playwright/Chromium issue; check for missing dependencies
  • SQLite locking (dev) → WAL mode should prevent, but check for long-running writes
  • DB connection errors → verify POSTGRES_HOST points to correct container name
  • CI/CD: Gitea Actions on PR to main — builds Docker image, auto-generates CalVer version (YYYY.MM.BUILD) on merge

Important

  • Docker image installs only Playwright Chromium (not all browsers) to optimize size
  • Teams have dynamic card pricing based on market activity
  • Supports both human players and AI teams
  • Gauntlet events use special reward structures and card pools
