admin

Admin example (ADMIN-1 through ADMIN-3, relationships #223)

Minimal framework.App with Config.Auth.Mode = config.AuthModeCookie, SQLite, and admin.Register of a widget.Widget model plus its relation targets (warehouse.Warehouse, part.Part). framework.New mounts empty admin Huma routes and the framework-owned SPA under /admin/ in cookie mode; this example registers three models from their feature packages. JWT-only apps do not get these routes.

Relationships (#223)

Widget carries all three relation kinds, and its RegisterAdmin leaves Fields empty so admin.FieldsFrom derives them from the GORM model — no per-field wiring:

• belongs_to — WarehouseID (a *uint, so genuinely optional) + Warehouse derive to a warehouse_id picker backed by the warehouses list, labelled by name. Leaving it unset stores NULL; the create still succeeds (a non-nullable uint FK would reject "no warehouse" under foreign key enforcement).
• many_to_many — Warehouses []warehouse.Warehouse (many2many:widget_warehouses) derives to a multi-select; a write syncs the join table in the same transaction as the row.
• has_many — Parts []part.Part derives to a read-only view of the children's ids (Part carries the widget_id back-reference). A write to it is rejected.

Part.widget_id is a plain integer, not a picker: Part cannot hold a Widget association without an import cycle, which is the same constraint gombit make resource ... has_many:Part documents.

See docs/admin.md, docs/cli.md (relation grammar), and ADR-013.

Run

go run ./examples/admin

Admin UI: http://127.0.0.1:8082/admin/. Sign in with the seeded superuser admin@example.com / correct-horse-battery-staple. The widgets screen appears because widget.RegisterAdmin called admin.Register — there is no per-model React file.

The example also seeds viewer@example.com with the same password and adds that user to a viewers group containing only admin.widgets.view. The viewer can open the widget list and detail screens. The API returns 403 for create, update, and delete, and the SPA hides those buttons. The superuser sees every enabled action without needing permission rows.

/auth/register never sets IsSuperuser. When the example is pointed at a file-backed SQLite DSN, use gombit createsuperuser (see below).

E2E (meta + one CRUD cycle)

A cookie jar is required. CSRF must be double-submitted on POST/PATCH/DELETE.

JAR=$(mktemp)

CSRF_BODY=$(curl -sS -c "$JAR" -b "$JAR" http://127.0.0.1:8082/api/v1/auth/csrf)
CSRF=$(python3 -c 'import json,sys; print(json.load(sys.stdin)["data"]["csrf_token"])' <<<"$CSRF_BODY")

curl -sS -c "$JAR" -b "$JAR" -X POST http://127.0.0.1:8082/api/v1/auth/login \
  -H 'Content-Type: application/json' -H "X-CSRF-Token: $CSRF" \
  -d '{"email":"admin@example.com","password":"correct-horse-battery-staple"}'

rm -f "$JAR"

Anonymous calls return D10 authentication (401). An authenticated user without the registered action permission gets D10 authorization (403). Unknown slugs/ids are not_found. A disabled action is authorization even for a superuser.

Create a superuser against a file DSN

When the example is pointed at a file-backed SQLite DSN instead of the in-memory default, use gombit createsuperuser:

GOMBIT_DATABASE_DRIVER=sqlite \
GOMBIT_DATABASE_DSN='file:admin-example.db?cache=shared&_fk=1' \
GOMBIT_JWT_SECRET='dev-only-example-jwt-secret-not-for-prod' \
GOMBIT_AUTH_MODE=cookie \
go run ./cmd/gombit createsuperuser --no-input \
  --email admin@example.com --password correct-horse-battery-staple
