No changes needed - to `down()` either — the down() drops the columns, which is the - correct mirror of `up()`. - -3. **Keep `UpdateSystemCategoryKeys1700000000300` unchanged.** Its - `INSERT` already lists `created_at` and `updated_at` - (`backend/src/database/migrations/1700000000300-UpdateSystemCategoryKeys.ts:51`). - -4.

Backend Logic & APIs - -No controller / service logic changes are required. With the schema -fix, `AdminCategoriesService.list()` at -`backend/src/modules/admin/categories.service.ts:30-37` will resolve -`c.created_at` and `c.updated_at` and return rows that satisfy the -existing `CategoryView` shape used by the front-end. - -If desired, the controller surface can stay untouched -(`backend/src/modules/admin/admin-categories.controller.ts:30-34`) — -no new endpoint is needed. - -### 3. Frontend UI Integration - -1. **Update `frontend/src/app/features/admin/general.pure.ts`** to - expose a small `eventEndFieldMessage(controlErrors, crossField)` pure - helper that returns the canonical Event End field error string: - - | `controlErrors?.['invalidDatetime']` | `form.errors?.['endBeforeStart']` | Returned message | - |---------------------------------------|-----------------------------------|----------------------------------------------------------| - | `true` | any | `"Event end must be a valid ISO-8601 datetime."` | - | falsy | `true` | `"Event end must be after event start."` | - | falsy | falsy | `null` | - - This mirrors the existing `datetimeMessage` pattern and keeps the - template a thin consumer. - -2. **Update `frontend/src/app/features/admin/general.component.ts`**: - - - Replace the current `@if (showEventEndError())` / - `@if (eventEndCrossFieldError())` pair (lines 123-128) with a single - `eventEndFieldMessage` consumer that always renders inside the - `data-testid="general-eventEnd-error"` element. When both - validators are off, the element is absent. - - Bind `[attr.aria-invalid]` to `true` when - `eventEndFieldMessage(...)` is non-null, otherwise null. - - Bind `[attr.aria-describedby]` to `"general-eventEnd-error"` and - bind `[attr.title]` to the resolved message string in that same - case. - - Drop the separate `general-endBeforeStart` block **only after** - confirming no existing test asserts on it (a quick search of - `tests/frontend` shows it is only mentioned in - `tests/frontend/admin-general-pure.spec.ts` as a value assertion on - the constant `endBeforeStartMessage`, not as a DOM query). If a test - asserts on the element, keep it as a redundant duplicate or update - the test. - -3. **Do not change** the form-level validator at - `general.pure.ts:41-51` — it already returns `{ endBeforeStart: true }` - for both `e < s` and `e === s`. The Job requirement is purely a - rendering fix. - -## 4. Test Strategy - -- **Target backend test file:** `tests/backend/migrations.spec.ts` (new - spec). Add a focused `describe('InitSchema creates category with - created_at + updated_at columns')` that: - - Boots `AppModule` against `:memory:` SQLite. - - Calls `dataSource.runMigrations({ transaction: 'each' })`. - - Queries `PRAGMA table_info("category")` and asserts the returned - names contain both `created_at` and `updated_at`. - - Sanity-checks that `AdminCategoriesService.list()` returns an array - (length ≥ 6 seeded system rows) without throwing — this is the - regression test that prevents the user-visible - `no such column: c.created_at` error from coming back. - -- **Target backend test file:** `tests/backend/admin-categories-service.spec.ts` - (extend). Add one `it('list() succeeds against the migrated schema and - returns seeded rows')` that runs after the existing CRUD specs. The - existing tests already use `synchronize: true` which would have masked - the bug; the new test should rely on the **migrations** path so it - actually exercises the schema the production app uses. - -- **Target frontend test file:** `tests/frontend/admin-general-pure.spec.ts` - (extend). Add a `describe('eventEndFieldMessage')` block with three - focused cases: - 1. Returns the ISO message when `invalidDatetime` is set, even if - `endBeforeStart` is also set. - 2. Returns the end-before-start message when `invalidDatetime` is - absent and `endBeforeStart` is set. - 3. Returns `null` when both are absent. - -- **Mocking Strategy:** No new mocks. Backend spec uses the real - `AppModule` against `:memory:` SQLite (already the pattern in - `tests/backend/admin-validation.spec.ts` and - `tests/backend/admin-general-service.spec.ts`). Frontend spec - continues to assert on the pure helper return values only. - -- **Single command:** `npm test` from `/repo` runs the full suite - (already in `package.json:14`). Frontend and backend can also be run - separately via `npm run test:backend` / `npm run test:frontend`. - -## 5. Persistent Project Data (/data) - -Not applicable to this Job. The DB schema change is a migration; tests -use `:memory:` SQLite and never write to `/data`.

Architectural Reconnaissance +- **Codebase style & conventions:** TypeScript monorepo with an Angular 17 standalone SPA and NestJS backend. The General Settings screen uses a strictly typed, non-nullable reactive form in `frontend/src/app/features/admin/general.component.ts`, while reusable formatting and validation logic is extracted to pure functions in `frontend/src/app/features/admin/general.pure.ts`. The component loads backend ISO timestamps through `toDatetimeLocal`, submits form values through `toIsoUtc`, and uses async/await around the promise-based `AdminService` API facade. +- **Data Layer:** NestJS persists general settings as string key/value rows through `SettingsService`. `AdminGeneralService.updateSettings` writes `eventStartUtc` and `eventEndUtc` verbatim after `GeneralSettingsSchema` validates timezone-aware ISO-8601 strings and strict start/end ordering. No database schema or migration is required; the defect is isolated to frontend conversion of UTC-labelled `datetime-local` values. +- **Test Framework & Structure:** Root Jest 29 multi-project configuration with `ts-jest`; frontend tests run in jsdom from the dedicated `tests/frontend/` folder. `npm test` runs backend and frontend projects together, while `npm run test:frontend` runs the focused frontend project. Existing pure-helper coverage is in `tests/frontend/admin-general-pure.spec.ts`, which is the appropriate lightweight regression location and requires no browser UI. +- **Required Tools & Dependencies:** No new system tools, global CLI utilities, package dependencies, persistent `/data` assets, or `setup.sh` changes are required. The implementation uses built-in JavaScript `Date` UTC construction/serialization and the existing Jest toolchain. + +## 2. Impacted Files +- **To Modify:** + - `frontend/src/app/features/admin/general.pure.ts` — make `toIsoUtc` interpret the numeric components of the UTC-labelled `datetime-local` string as UTC rather than as the browser's local timezone. + - `tests/frontend/admin-general-pure.spec.ts` — add a focused timezone regression proving the displayed UTC wall-clock components serialize unchanged and preserve existing empty/invalid behavior. +- **To Create:** None. + +## 3. Proposed Changes +1. **Database / Schema Migration:** No changes. The existing setting keys and backend zod schema already accept and persist canonical UTC ISO strings correctly. +2. **Backend Logic & APIs:** No changes. `PUT /api/v1/admin/general/settings` already validates timezone-aware ISO-8601 input, enforces `eventEndUtc > eventStartUtc`, and stores the payload without timezone conversion; `GET /api/v1/event/status` therefore reflects whatever canonical instant the frontend sends. +3. **Frontend UI Integration:** + 1. Update `toIsoUtc` in `general.pure.ts` to parse the `datetime-local` year, month, day, hour, minute, and optional second/fraction components as UTC components, then create the timestamp with `Date.UTC(...)` and return `toISOString()`. + 2. Preserve the helper's current contract for empty values (`''`) and invalid values (return the original string), so the existing reactive-form validation and negative save paths remain unchanged. + 3. Keep `toDatetimeLocal` unchanged because it already renders backend timestamps from UTC getters. Together, `toDatetimeLocal(iso)` and `toIsoUtc(local)` will become true timezone-independent inverses for the minute-precision native inputs used by `AdminGeneralComponent`. + 4. Keep `AdminGeneralComponent.onSubmit` and the service/API contract unchanged; both event fields already pass through `toIsoUtc`, so correcting the shared helper fixes start and end submissions without UI or backend rewiring. + +## 4. Test Strategy +- **Target Unit Test File:** `tests/frontend/admin-general-pure.spec.ts`. +- **Mocking Strategy:** No external boundaries need mocking because the defect is entirely in a pure function. Add a minimal deterministic regression around `toIsoUtc('2027-03-15T08:30') === '2027-03-15T08:30:00.000Z'` and the corresponding end value `2027-03-17T16:45`, explicitly exercising the America/Los_Angeles/PDT scenario without launching a UI. Prefer running the focused Jest process with `TZ=America/Los_Angeles` (or isolate a small child Jest invocation configured with that environment) so the test fails against the current local-time implementation and passes only when conversion is browser-timezone independent. Retain or extend the existing empty-input assertion and add only the key invalid-input assertion if needed to lock the helper's fallback contract. Verify with the root single-command suite (`npm test`) plus the existing root build/type-check path (`npm run build`); no visual confirmation or persistent test data is involved. diff --git a/docs/guides/admin-general-settings.md b/docs/guides/admin-general-settings.md index df3f3b3..d617c83 100644 --- a/docs/guides/admin-general-settings.md +++ b/docs/guides/admin-general-settings.md @@ -2,8 +2,8 @@ type: guide title: Admin — General Settings description: How an admin edits required platform-wide settings, including the validated event window, from the /admin/general page. -tags: [guide, admin, settings, general, tester, datetime, validation] -timestamp: 2026-07-22T14:50:25Z +tags: [guide, admin, settings, general, tester, datetime, validation, utc, timezone] +timestamp: 2026-07-22T15:09:39Z --- # When this view is available @@ -56,7 +56,8 @@ The page is a single reactive form with these controls (every * **Initial load:** `loading() === true` renders `general-loading`.
