tags: [events, postgres, sqlc, htmx, templ]

requires:
  - phase: 10-events
    provides: Plan 01 event schema, calendar tab, create form, and create/list routes
provides:
  - Parent-scoped event edit form and update handler
  - Hard-delete event flow with inline confirmation
  - Event mutation authorization through loadOwnedEvent
  - Update validation for required fields and end-after-start time ordering
affects: [events, tablo-detail, calendar]

tech-stack:
  added: []
  patterns:
    - "loadOwnedEvent composes loadOwnedTablo with child lookup scoped by tablo_id"
    - "Inline edit and delete fragments target #event-form-slot and refresh #events-tab after mutation"

key-files:
  created: []
  modified:
    - backend/internal/db/queries/events.sql

    - backend/internal/web/handlers_events.go
    - backend/internal/web/router.go
    - backend/templates/events.templ
    - backend/templates/events_forms.go

key-decisions:
  - "Delete is a hard delete through DELETE FROM events with no deleted_at field."
  - "Update reuses the create form parser so create and edit enforce the same date/time validation."
  - "Mutation routes load the parent tablo first and then fetch the child event by id plus tablo_id."

patterns-established:
  - "Event mutation handlers return 404 for inaccessible parent or child resources."
  - "Event edit validation errors re-render the edit form into #event-form-slot with status 422."

# Phase 10: Events Plan 02 Summary

**Inline event edit, update validation, and hard delete for tablo-owned calendar events**

## Performance

- **Duration:** ~18 min
- **Started:** 2026-05-15T22:29:00Z
- **Completed:** 2026-05-15T22:47:00Z
- **Tasks:** 2
- **Files modified:** 6

## Accomplishments

- Added DB-backed RED coverage for edit rendering, update success, update validation, delete, and non-owner mutation denial.
- Added `UpdateEvent` and `DeleteEvent` SQLC queries scoped by both `id` and `tablo_id`.
- Added `loadOwnedEvent` plus edit, update, delete-confirm, and delete handlers.
- Added inline edit and delete confirmation fragments using the planned UI copy.

## Task Commits

Each task was committed atomically:

1. **Task 1: Add RED coverage for edit, update, delete, and ownership** - `e5f083d` (test)
2. **Task 2: Implement inline edit and hard delete** - `614003f` (feat)

## Files Created/Modified

- `backend/internal/db/queries/events.sql` - Adds update and hard-delete queries.
- `backend/internal/web/handlers_events_test.go` - Covers edit, update, delete, validation, and ownership behavior.
- `backend/internal/web/handlers_events.go` - Adds owned-event loading and mutation handlers.
- `backend/internal/web/router.go` - Mounts event edit, update, delete-confirm, and delete routes.
- `backend/templates/events.templ` - Adds edit form and delete confirmation fragments.
- `backend/templates/events_forms.go` - Adds URL helpers for event mutation routes.

## Decisions Made

- Update and delete are always scoped to the owned parent tablo before touching the event row.
- Delete is a hard delete, matching the plan's no-restore requirement.
- Edit uses a separate fragment from create so labels, button copy, and validation rerendering remain clear.

## Deviations from Plan

None - plan executed as written.

## Issues Encountered

None.

## User Setup Required

None - no external service configuration required.

## Next Phase Readiness

The event CRUD surface is complete. Plan 10-03 can add direct-link and month query handling refinements on top of the existing Events tab and mutation routes.
