DB-backed email-template editor for global_admins, replacing the
"Kommt bald" placeholder. Admins can edit invitation, deadline_digest,
and the shared base wrapper for both DE and EN, preview against sample
data, save with versions, and reset to the embedded default.
Backend:
- Migration 026 adds paliad.email_templates (active row per (key, lang))
and paliad.email_template_versions (append-only, retained 20 deep).
- EmailTemplateService — GetActive falls through to the embedded per-
language file when no DB row, Save validates parse + structural
invariants and writes a version, Reset deletes the active row, Restore
copies a version back. Mutations require DB; reads work without.
- MailService now consults the service for body and subject and falls
back to the embedded default if the active row is malformed at parse
time — a corrupt admin save can never wedge the send path.
- Subjects move from Go (buildDigestSubject + inviteSubject) to
text/template strings stored in the (key, lang) row. Default subjects
ship with a {{/* keep this phrasing */}} comment pointing at the
reminder-redesign doc so the SLO framing rationale survives edits.
- Bilingual templates split into per-language files (invitation.de.html
+ .en.html, deadline_digest.de.html + .en.html, base.de.html + .en.html).
No more {{if eq .Lang}} branching inside templates.
- Handlers under /api/admin/email-templates/* gated by the existing
RequireAdminFunc(users) admin middleware, same shape as /admin/team.
Frontend:
- /admin/email-templates list page — three cards (one per template),
each linking to DE + EN editors with their last-modified status.
- /admin/email-templates/{key}?lang=de three-pane editor — subject + body
textarea + variable docs + actions on the left, sandboxed iframe
preview + version log on the right. 500 ms debounced live preview;
save validates server-side (422 on parse error, surfaced inline).
- admin.tsx flips the Email-Templates card from PLANNED to verfügbar.
- 50 new i18n keys (DE + EN) for the editor surface.
Tests: GetActive fallback path, ValidateTemplate happy + sad paths,
SaveRequiresStore on no-DB service, RenderTemplate body + subject
goldens, full SYSTEMAUSFALL/SYSTEM FAILURE subject matrix.
Smoke (knowledge-platform-only run, no DB/auth):
- GET /admin/email-templates → 302 to /login
- GET /api/admin/email-templates → 401
- go build/vet/test clean, bun run build clean
Design: docs/design-email-templates-2026-04-29.md.
Unified /einstellungen page replaces the standalone CalDAV screen. Three
tabs today (Profil / Benachrichtigungen / CalDAV); adding more is additive
(one <a> in the tab nav, one <section> panel, one loader). Tab switching
is client-side from ?tab=<name> — default tab is Profil.
Profil tab lets users fix onboarding data without admin intervention:
display name, office, role, Dezernat, language. Email is read-only (the
source of truth is auth.users and an account-level change is out of
scope for the settings page).
Benachrichtigungen tab exposes deadline reminder preferences as a master
toggle plus three per-kind sub-toggles (overdue / tomorrow / weekly).
Preferences land in paliad.users.email_preferences (JSONB); missing keys
are treated as opt-in so existing users keep the behaviour they had
before the page shipped.
CalDAV tab is the old /einstellungen/caldav screen ported inline.
/einstellungen/caldav now 301-redirects to /einstellungen?tab=caldav so
bookmarks keep working.
Backend:
- PATCH /api/me (handlers/users.go) mutates the caller's paliad.users
row. Attempts to include "email" in the body return 400 — the field is
always server-authoritative.
- UserService.UpdateProfile builds a dynamic UPDATE from the pointer
fields supplied; omitted keys are left untouched. Re-uses the
admin-bootstrap guard for role changes.
- GetByID SELECT now includes lang + email_preferences so /api/me
returns the data the settings page needs without a second round-trip.
- ReminderService consults email_preferences before sending — the helper
reminderEnabled covers the master switch and per-kind overrides; corrupt
JSON falls back to on so a bad row can't silence reminders.
- Migration 017 adds email_preferences jsonb NOT NULL DEFAULT '{}' and
upgrades lang from nullable (from 016) to NOT NULL DEFAULT 'de' with a
one-shot backfill. Down restores the nullable lang and drops
email_preferences.
Model change: User.Lang moved from *string to string — it's NOT NULL in
the DB now, so the indirection was carrying no information. Inviter.Lang
and reminder row structs followed suit; the templates and callers used
""/"en" comparisons that translate 1:1.
Sidebar: the "Einstellungen" group now links to /einstellungen (instead
of just /einstellungen/caldav); the CalDAV sub-item is folded into the
tab nav on the page itself.
Tests: reminderEnabled has table-driven coverage (master switch,
per-kind, corrupt JSON, non-bool values). DB-backed user tests still
skip without TEST_DATABASE_URL as before.
Verified: go build ./..., go vet ./..., go test ./..., bun run build —
all clean.
- internal/services/mail_service.go: SMTP/TLS sender (implicit TLS on 465),
html/template rendering, branded base layout + content templates, silent
no-op when SMTP_* unset.
- internal/services/reminder_service.go: hourly scanner for Fristen that are
overdue / due tomorrow / due within the week (Monday digest). Dedup via
paliad.reminder_log (24h window).
- internal/services/invite_service.go: POST /api/invite flow with domain
whitelist, in-memory 10/day/user rate limit, audit row in
paliad.invitations.
- internal/handlers/invite.go: POST + GET /api/invite handlers.
- Sidebar "Kolleg:in einladen" button + modal on every page.
- migration 016: paliad.reminder_log, paliad.invitations, users.lang column.
- docker-compose: SMTP_* + PALIAD_BASE_URL env vars.
- docs/feature-roadmap.md: documented Supabase auth-SMTP routing as open
question; current pilot keeps identity mails on Supabase default sender.
Rationale: get Paliad off Supabase's best-effort outbound for the
inbox-facing stuff (reminders, invitations) and move deadline nudges from
passive dashboard to active email. Custom Supabase auth SMTP is blocked on
the shared ydb.youpc.org instance — deferred until Paliad has its own
project or GoTrue webhook relay.
