- "TDD RED/GREEN cycle: failing tests committed first, then implementation"
|
|
- "LEFT OUTER JOIN chain with .switch(Printer) for multi-FK queries in Peewee"
|
|
- "Null-safe driver_desc parse: check printer.driver_id before json.loads"

key-decisions:
|
|
- "Detail page is a full-page template (not partial) — simpler than partial injection into printers.html"
|
|
- "Route lives in pages.py (not printers.py) because it returns a full HTML page, not an HTMX fragment"
|
|
|
|
patterns-established:
|
|
- "Full-page detail routes in pages.py; HTMX fragment routes in api/printers.py"

# Phase 3 Plan 02: Printer Detail Page Summary
|
|
|
|
**GET /printers/{id} detail page with pre-populated config fields, associated driver info via FK, and disabled Regenerate Package button placeholder for Phase 4**
|
|
|
|
## Performance
|
|
|
|
- **Duration:** ~2 min
|
|
- **Started:** 2026-04-10T12:03:29Z
|
|
- **Completed:** 2026-04-10T12:05:56Z
|
|
- **Tasks:** 2
|
|
- **Files modified:** 4
|
|
|
|
## Accomplishments
|
|
|
|
- Printer detail route with Peewee multi-FK LEFT OUTER JOIN queries returning 200 or 404
|
|
- Full-page Jinja2 template showing all 8 config fields, driver package name, driver names list, and architecture
|
|
- Graceful "No driver assigned" display when driver FK is null
|
|
- Printer names in list view are now clickable navigation links to their detail pages
|
|
- 3 new integration tests; full suite at 61 passing
|
|
|
|
## Task Commits
|
|
|
|
1. **Task 1: Write failing tests for printer detail page** - `6e7892e` (test)
|
|
2. **Task 2: Implement printer detail route, template, and list nav links** - `cad664c` (feat)
|
|
|
|
**Plan metadata:** (committed next)
|
|
|
|
## Files Created/Modified
|
|
|
|
- `imptune/api/pages.py` - Added GET /printers/{printer_id} route with LEFT OUTER JOIN on Client and Driver
|
|
- `imptune/templates/printer_detail.html` - Full-page detail template with config, driver info, and regenerate placeholder
|
|
- `imptune/templates/partials/printer_list.html` - Printer name column wrapped in anchor tag linking to detail page
|
|
- `tests/test_printer_crud.py` - Added 3 tests: detail with driver, 404 not found, detail without driver
|
|
|
|
## Decisions Made
|
|
|
|
- Detail page uses a full-page template (not a partial) to avoid coupling it to the printers list layout
|
|
- Route placed in `pages.py` since it returns a full HTML page, keeping HTMX fragment routes in `api/printers.py`
|
|
|
|
## Deviations from Plan
|
|
|
|
None - plan executed exactly as written.
|
|
|
|
## Issues Encountered
|
|
|
|
None.
|
|
|
|
## User Setup Required
|
|
|
|
None - no external service configuration required.
|
|
|
|
## Next Phase Readiness
|
|
|
|
- PRNT-10 satisfied: saved configs are retrievable with driver association intact
|
|
- "Regenerate Package" button is present and disabled, ready for Phase 4 to wire up
|
|
- No blockers for Phase 4 script generation work
