phase: 10-events
plan: 01
subsystem: events
tags: [events, postgres, sqlc, htmx, templ]

requires:
  - phase: 09-etapes
    provides: Tablo detail navigation patterns and HTMX tab fragments reused for the Events tab
provides:
  - Events table with local date and time fields scoped to tablos
  - SQLC create, fetch, and month-range list queries for events
  - Server-rendered Events tab with month grid and inline create form
  - Event create validation for required fields and end-after-start time ordering
affects: [tablo-detail, events, planning, calendar]

tech-stack:
  added: []
  patterns:
    - "EventsDeps injected through NewRouter alongside existing feature deps"
    - "Server-rendered HTMX tab fragment refreshes the whole Events tab after create"
    - "Local event_date/start_time/end_time stored as Postgres date/time values"

    - backend/templates/tablos.templ
    - backend/internal/web/handlers_tablos.go
    - backend/internal/web/handlers_files.go

key-decisions:
  - "Use local date/time columns rather than timestamptz for scheduled event display."
  - "Refresh the entire Events tab after create to keep month navigation and event rows consistent."
  - "Keep event access scoped through loadOwnedTablo and parent-scoped queries."

patterns-established:
  - "Event handlers parse YYYY-MM, YYYY-MM-DD, and HH:MM into pgtype values at the web boundary."
  - "Calendar data is built in Go and rendered by templ as a 42-cell month grid."

# Phase 10: Events Plan 01 Summary

**Tablo-scoped event creation with local date/time storage and a server-rendered month calendar**

## Performance

- **Duration:** ~20 min
- **Started:** 2026-05-15T22:05:00Z
- **Completed:** 2026-05-15T22:28:58Z
- **Tasks:** 2
- **Files modified:** 20

## Accomplishments

- Added the `events` table, event SQLC queries, and generated DB accessors.
- Added authenticated Events routes for tab display, inline creation, canceling the create form, and POST create.
- Extended the tablo detail page with an Events tab that renders a month grid and created event titles.
- Added DB-backed handler coverage for rendering, create success, invalid end time validation, and ownership denial.

## Task Commits

Each task was committed atomically:

1. **Task 1: Add RED coverage for create-and-list calendar slice** - `4fbd960` (test)
2. **Task 2: Implement event creation and month listing** - `0bfe8cf` (feat)

## Files Created/Modified

- `backend/migrations/0008_events.sql` - Creates the event schema, constraints, and indexes.
- `backend/internal/db/queries/events.sql` - Adds create, fetch, and month-range list queries.
- `backend/internal/web/handlers_events.go` - Adds event calendar rendering and create handlers.
- `backend/templates/events.templ` - Renders the Events tab, month grid, and create form.
- `backend/templates/events_forms.go` - Provides event form and calendar view models/helpers.
- `backend/templates/tablos.templ` - Adds the Events tab to the tablo detail surface.
- `backend/internal/web/router.go` - Wires event routes and `EventsDeps`.
- `backend/cmd/web/main.go` - Injects event dependencies into the router.
- `backend/internal/web/*_test.go` - Updates router construction and adds event handler tests.

## Decisions Made

- Events store `event_date`, `start_time`, and nullable `end_time` as local Postgres date/time types to avoid timezone conversion in the calendar.
- The create flow refreshes the whole `#events-tab` fragment after success so the calendar, month controls, and form slot stay synchronized.
- Event list/create authorization goes through `loadOwnedTablo`, matching files and etapes ownership behavior.

## 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 schema, router dependency, month calendar, and create form are in place. Plan 10-02 can build directly on this surface by adding owned-event edit, update, and delete handlers plus inline form fragments.
