Phase 11 Plan 02: Printer Edit Modal (UIE-01) Summary

One-liner: HTMX PATCH route + Pico CSS native dialog edit modal with Alpine.js port guard and Playwright E2E coverage.

What Was Built

UIE-01 is now complete: every printer row in the library has an Edit button that opens a pre-filled native <dialog> modal. Submitting the form sends a HTMX PATCH to /printers/{id}, closes the modal, and refreshes the printer list in-place without a page reload.

Key Changes

• imptune/api/printers.py — Added PATCH /{printer_id} route handler with full validation (name/ip/port required, duplex/paper enum checks). Optional ip_address and port_name fall back to existing values when not submitted. Updated _render_printer_list to pass clients and driver_data in the template context for modal pre-population. Imported Driver at module level.

• imptune/templates/partials/printer_edit_modal.html (new, 98 lines) — Pico CSS native <dialog> with Edit trigger button and HTMX PATCH form. Uses hx-on::after-request to close the modal on success. Alpine.js x-data sets portEdited: true so editing IP does not overwrite a manually-set port. Pre-fills all printer fields including driver/client selects with selected conditional.

• imptune/templates/partials/printer_list.html — Actions <td> updated: {% include "partials/printer_edit_modal.html" %} inserted before the Delete button, inside the {% for p in printers %} loop so p is in scope.

• tests/e2e/test_printer_edit.py (new) — Two Playwright E2E tests: modal open and pre-fill verification; submit updates list via HTMX PATCH. Row targeting uses page.locator("tr", has=page.locator("a", has_text="OriginalName")) to handle session-scoped live_server accumulating data across tests.

Deviations from Plan

Auto-fixed Issues

1. [Rule 2 - Missing functionality] ip_address and port_name made optional in PATCH handler

• Found during: Task 1 — reviewing Wave 0 test scaffold test_patch_printer
• Issue: The plan specified ip_address: str = Form(...) and port_name: str = Form(...) as required, but the existing RED scaffold test only sends {"name": "Updated Name"}. The handler would have returned 422 Unprocessable Entity.
• Fix: Changed ip_address and port_name to Form("") with fallback to printer.ip_address / printer.port_name when empty, preserving validation logic while passing the test.
• Files modified: imptune/api/printers.py
• Commit: 4b212b6

2. [Rule 1 - Bug] E2E test_printer_edit_submit_updates_list used wrong selector for session-scope isolation

• Found during: Task 2 — E2E test run
• Issue: page.click("button:has-text('Edit')") clicked the first Edit button in the list, which belonged to a printer from a previous test (session-scoped live_server). The targeted printer ("OriginalName") was not updated.
• Fix: Changed to page.locator("tr", has=page.locator("a", has_text="OriginalName")).locator("button:has-text('Edit')").click() to target the specific row. Also updated assertion to check anchor text (a:has-text) rather than td:first-child inner text, and used page.wait_for_selector("a:has-text('UpdatedName')") for HTMX swap completion.
• Files modified: tests/e2e/test_printer_edit.py
• Commit: 7b948b6

Success Criteria Check

• Every printer row has an Edit button
• Clicking Edit opens a native dialog pre-filled with that printer's current data
• Submitting the edit form sends HTMX PATCH, closes the modal, and updates the list
• PATCH /printers/{id} validated via test_patch_printer (GREEN)
• PATCH /printers/9999 returns 404 (confirmed by test_patch_printer_not_found)
• E2E tests pass: modal opens, name is pre-filled, submit updates list

Self-Check: PASSED
