Existing app (single-file Tkinter/ttkbootstrap desktop tool for logging blood-drive work assignments and mapping them) plus the first round of improvements: - Data safety: atomic CSV writes (tmp + fsync + os.replace), rotating backups in data/backups/ (startup + before every change, keep 20), fallback to empty/backup on missing/empty/corrupt orte.csv. - Geocoder robustness: per-item try/except so the worker thread survives failures; GeocodingUnavailable + one-time "service unreachable" dialog. - Input: DateEntry calendar picker with parse_date() validation; manual lat/lon fields in the edit dialog; Tab 2 highlights/filters rows without coordinates and adds a right-click "Koordinaten suchen". - Logging to data/app.log; shared autocomplete helpers; config constants; map fit_bounds. docs/ describes current state, architecture, data model, setup (Linux Mint), and the full improvement roadmap. data/orte.csv is gitignored for now.

# DRK Blutspende – Arbeitsorte: Dokumentation
|
||
|
||
Developer/maintainer documentation for the **Arbeitsorte-Logger**, a small
|
||
desktop app that records blood-drive work assignments (date + city + postal
|
||
code) and plots them on an interactive map.
|
||
|
||
> Context: built as a personal tool for a single user, running locally on a
|
||
> **Linux Mint laptop**. Ease of use for a non-technical user is the primary
|
||
> design constraint. There is no server, no multi-user story, and no network
|
||
> dependency beyond geocoding and the map tiles.
