Removes DEFAULT_MODEL in favour of a force_model setting configurable
via the admin UI. When set, every proxy request's model field is
overridden, preventing uncoordinated model switches during lab sessions.
Updates schemas, admin API, all three proxy endpoints, frontend,
init_db, and docs (README, DOCKERHUB, KURZANLEITUNG).
Add a second usage log line after each proxy response with actual ↑prompt ↓completion
token counts from Ollama (prompt_eval_count/eval_count for native endpoints,
usage object for OpenAI endpoint). Also adds KURZANLEITUNG.md for students and
colleagues covering API access, model selection, Python examples, opencode setup,
and quota/admin information.
- Normalize OpenAI array-format content to string to fix connection reset
- Add error.log with rotating handler for proxy and stream errors
- Add global unhandled exception handler returning JSON 500
- Write OLLAMA_URL/DEFAULT_MODEL env vars to DB on startup (reset on restart)
- Add extra_hosts to docker-compose.yml for host.docker.internal on Linux
- Show warning in admin UI when Ollama URL is unreachable
- Return reachable: true/false from /api/ollama-models endpoint
Backend:
- Fix Content-Length mismatch by not forwarding client headers to Ollama
- Proxy /v1/chat/completions directly to Ollama's OpenAI-compatible endpoint
(eliminates manual Ollama↔OpenAI format conversion, fixes tool use)
- Add streaming support via SSE passthrough
- Fix ollama_url /v1 suffix stripped on save
- Replace BaseHTTPMiddleware with FastAPI global dependency (fixes double logging)
- Add rotating usage log (8 KB, logs key name + model + token estimate + prompt preview)
- Add httpx timeout 300s
- Add activate and delete endpoints for API keys
- Return usage data (tokens/requests) in GET /api/api-keys
Frontend:
- Admin table: remove ID column, status as icon, icon-only action buttons with CSS tooltips
- Add activate + delete buttons; edit available for inactive keys too
- Quota columns: fixed equal width, progress bars with k-unit formatting
- Create form: structured layout matching edit form style
- Edit form: token inputs in k units (÷1000 display, ×1000 on save)

- Remove User/Quota models; quota fields now live directly on APIKey
- Admin UI: login, API key management, settings (Ollama URL/model), proxy info display
- .env/.env.example: ADMIN_PASSWORD, PROXY_HOST/PORT, DATABASE_URL, APP_TZ
- Admin API runs on 127.0.0.1 only; proxy host/port configurable
- API keys support optional expires_at; verified against Europe/Berlin timezone
- Daily/monthly quota resets use Europe/Berlin midnight boundary
- Fix all tests to use new flat model; add expiry tests
