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
