Admin CRUD Implementation Plan

For agentic workers: REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (- [ ]) syntax for tracking.

Goal: The authenticated admin surface the React UI consumes — full catalogue-record lifecycle (create/read/list/update/delete + flexible-field values), read-only field-definition listing, and management of the controlled vocabularies / terms / authority records that catalogue fields reference. All gated by the Authorized<Cap> framework and audited with the real acting user.

Architecture: Pure HTTP wiring over the existing db repositories (no new business logic; SQL stays in db). New axum route modules under crates/api/src/ register endpoints, each behind a typed capability extractor: reads require Authorized<ViewInternal> (admin reads see all visibility levels), writes require Authorized<EditCatalogue>. Writes record AuditActor::User(id) from the extracted AuthUser (advancing #7). Two new db read helpers (paginated object list + list_vocabularies) are added; everything else already exists.

Tech Stack: Rust 2024, axum 0.8, utoipa 5, sqlx 0.8, time (date parsing/formatting). Tests: #[sqlx::test(migrations = "../db/migrations")] + axum oneshot (with the session-cookie login helper from the auth tests).

Design decisions (approved)

• Scope: object lifecycle plus vocabulary/term/authority admin (the full slice that makes cataloguing usable end-to-end).
• Reads (ViewInternal) show all visibility levels; writes (EditCatalogue) — both roles. Delete is EditCatalogue (Editor + Admin).
• Create accepts initial visibility Draft or Internal (never Public — publishing goes through the stepwise POST .../visibility endpoint from the auth phase).
• Update edits the inventory-minimum fields but NOT visibility (the stepwise machine stays authoritative).
• Audit actor is the real user (AuditActor::User) on every admin write.
• Object list is paginated (limit/offset + total), same shape as the public surface (advances #10).
• Vocabulary/term/authority creation is not audited for now (the db create fns take no actor) — tracked as a follow-up; objects + users remain audited.

Prerequisites

• Postgres for tests; pass DATABASE_URL inline. cargo +nightly fmt (nightly). Clean clippy --all-targets -- -D warnings.
• Codename "biggus"/"dickus" must appear nowhere.
• The session/login test helpers exist in crates/api/tests/admin.rs — the new test files replicate the small login/session_cookie/seed_user helpers (or factor them into a shared tests/common/mod.rs; either is fine — keep it DRY within reason).

Existing building blocks (verified — do not reimplement)

• db::catalog: create_object(conn, actor, &ObjectInput) -> ObjectId; object_by_id(exec, ObjectId) -> Option<CatalogueObject>; update_object(conn, actor, id, &ObjectInput) -> bool; delete_object(conn, actor, id) -> bool; set_object_fields(conn, actor, id, &Map) -> Result<(), FieldError> (FieldError { ObjectNotFound, UnknownField(String), TypeMismatch{field,expected}, Unresolved{field,kind}, Db }); set_visibility (publish — already wired to POST /api/admin/objects/{id}/visibility).
• db::fields: list_field_definitions(exec) -> Vec<FieldDefinition>.
• db::vocab: create_vocabulary(exec, &str) -> Vocabulary; vocabulary_by_key; add_term(conn, &NewTerm) -> TermId; list_terms(exec, VocabularyId) -> Vec<Term>.
• db::authority: create_authority(conn, &NewAuthority) -> AuthorityId; list_by_kind(exec, AuthorityKind) -> Vec<Authority>.
• domain: ObjectInput, CatalogueObject, Visibility, FieldType (to_parts() -> (&'static str, Option<VocabularyId>, Option<AuthorityKind>)), FieldDefinition, Vocabulary{id,key}, Term{id,vocabulary_id,external_uri,labels}, NewTerm{vocabulary_id,external_uri,labels}, Authority{id,kind,external_uri,labels}, NewAuthority{kind,external_uri,labels}, AuthorityKind{Person,Organisation,Place} (as_str/from_db, serde lowercase), LocalizedLabel{lang,label}.
• auth: AuthUser{id,email,role}, Authorized<C>{user,..}, markers EditCatalogue, ViewInternal. AuthError → 401/403.

Task 1: db paginated object list + admin object READ surface

Files: modify crates/db/src/catalog.rs, crates/api/src/lib.rs, crates/api/src/openapi.rs, crates/api/Cargo.toml; create crates/api/src/admin_objects.rs, crates/api/tests/admin_objects.rs.

• Step 1: Add paginated readers to crates/db/src/catalog.rs (all visibility levels — admin sees everything). Place after list_objects:

/// List objects (all visibility levels) ordered by object number, with paging.
pub async fn list_objects_paged<'e, E>(
    executor: E,
    limit: i64,
    offset: i64,
) -> Result<Vec<CatalogueObject>, sqlx::Error>
where
    E: sqlx::PgExecutor<'e>,
{
    let sql = format!(
        "SELECT {OBJECT_COLUMNS} FROM object ORDER BY object_number LIMIT $1 OFFSET $2"
    );
    let rows = sqlx::query(&sql).bind(limit).bind(offset).fetch_all(executor).await?;
    rows.into_iter().map(map_object).collect()
}

/// Count all objects (for pagination totals).
pub async fn count_objects<'e, E>(executor: E) -> Result<i64, sqlx::Error>
where
    E: sqlx::PgExecutor<'e>,
{
    let row = sqlx::query("SELECT count(*) AS n FROM object").fetch_one(executor).await?;
    row.try_get("n")
}

• Step 2: Cargo — ensure time can parse/format dates. In crates/api/Cargo.toml, time is already a dependency; ensure the workspace time has the features ["serde", "macros", "parsing", "formatting"] (extend root [workspace.dependencies] time if needed). These let the handlers parse/format recording_date as YYYY-MM-DD.

• Step 3: Write the failing read tests crates/api/tests/admin_objects.rs (replicate the login/seed helpers from tests/admin.rs):

use api::{AppState, build_app, migrate_sessions};
use axum::body::Body;
use axum::http::{Request, StatusCode, header};

}

#[sqlx::test(migrations = "../db/migrations")]

    assert_eq!(missing.status(), StatusCode::NOT_FOUND);
}

• Step 4: Implement crates/api/src/admin_objects.rs (read parts in this task; write handlers added in Task 2, fields in Task 3 — but define the shared DTOs now):

//! Admin catalogue-object surface (authenticated). Reads require `ViewInternal`;
//! writes require `EditCatalogue` (added in later tasks).

use auth::{Authorized, ViewInternal};
use axum::{

• Step 5: Wire it. In crates/api/src/lib.rs add mod admin_objects; and .merge(admin_objects::routes()) in build_app. In crates/api/src/openapi.rs add admin_objects to the use and register admin_objects::list_objects, admin_objects::get_object in paths(...) and admin_objects::{AdminObjectView, AdminObjectPage, LabelView} in components(schemas(...)).

• Step 6: Run. DATABASE_URL=<url> cargo test -p db --test catalog_mutations (smoke that catalog still builds) then DATABASE_URL=<url> cargo test -p api --test admin_objects → PASS. Then cargo test -p api → all PASS.

• Step 7: Lint. cargo +nightly fmt; DATABASE_URL=<url> cargo clippy -p api -p db --all-targets -- -D warnings → clean.

• Step 8: Commit.

Task 2: admin object WRITE (create / update / delete)

Files: modify crates/api/src/admin_objects.rs, crates/api/src/openapi.rs, crates/api/tests/admin_objects.rs.

Task 3: flexible-field values + field-definition listing

Files: modify crates/api/src/admin_objects.rs, crates/api/src/openapi.rs, crates/api/tests/admin_objects.rs.

• Step 1: Write the failing tests (append to crates/api/tests/admin_objects.rs). Uses the Spectrum seed so a known field key exists, OR creates a field definition via db. Simplest: create a Text field definition directly via db::fields::create_field_definition, then set it.

#[sqlx::test(migrations = "../db/migrations")]
async fn set_fields_and_list_field_definitions(pool: PgPool) {
    use domain::{FieldType, LocalizedLabel, NewFieldDefinition};
    migrate_sessions(&db::Db::from_pool(pool.clone())).await.unwrap();

    db::fields::create_field_definition(&mut tx, &NewFieldDefinition {

    let id = catalog::create_object(&mut tx, AuditActor::System, &obj("A-1", "amphora", Visibility::Draft)).await.unwrap();
    tx.commit().await.unwrap();

    let app = build_app(state(pool.clone()));
    let cookie = login(&app, "ed@example.com", "pw-editor-123").await;

    // field-definitions list
    let defs = app.clone().oneshot(Request::builder().uri("/api/admin/field-definitions").header(header::COOKIE, &cookie).body(Body::empty()).unwrap()).await.unwrap();
    assert_eq!(defs.status(), StatusCode::OK);
    let defs_json: serde_json::Value = serde_json::from_slice(&defs.into_body().collect().await.unwrap().to_bytes()).unwrap();
    assert!(defs_json.as_array().unwrap().iter().any(|d| d["key"] == "inscription" && d["data_type"] == "text"));

    // set the field
    let set = app.clone().oneshot(Request::builder().method("PUT").uri(format!("/api/admin/objects/{id}/fields"))
        .header(header::COOKIE, &cookie).header(header::CONTENT_TYPE, "application/json")

}

• Step 2: Run to verify it fails.

}

Add to routes():

        .route("/api/admin/objects/{id}/fields", put(set_fields))
        .route("/api/admin/field-definitions", get(list_field_definitions))

NOTE: set_object_fields has replace semantics (the body is the complete desired field set). Document that in the handler doc comment so callers send all keys they want to keep.

• Step 4: Register OpenAPI — add set_fields, list_field_definitions to paths(...) and FieldDefinitionView to components(schemas(...)).

• Step 5: Run / Lint / Commit.

• Step 4: Wire + OpenAPI. mod admin_authorities; + .merge(admin_authorities::routes()) in build_app; register the 2 paths + AuthorityView, NewAuthorityRequest schemas (note: CreatedId/LabelInput/LabelView are already registered from earlier tasks — don't double-register).

• Step 5: Full workspace check.

cargo +nightly fmt --check
DATABASE_URL=<url> cargo clippy --workspace --all-targets -- -D warnings
DATABASE_URL=<url> MEILI_URL=<url> MEILI_MASTER_KEY=<key> cargo test --workspace

Expected: all green.

• Step 6: Commit.

git add crates/api && git commit -m "feat(api): admin authority management (create + list by kind)"

Self-Review (completed)

Spec coverage (VISION catalogue/vocab/authority [MVP]; arch spec §7, §9):

• Object create/read/list/update/delete + flexible fields → Tasks 1–3. ✓
• Reads (ViewInternal) see all visibility levels; writes (EditCatalogue); delete EditCatalogue → all tasks. ✓
• Create allows Draft/Internal, rejects Public; update never changes visibility → Task 2. ✓
• Real audit actor (AuditActor::User) on writes → Tasks 2–3. ✓
• Field-definition listing for form rendering → Task 3. ✓
• Vocabulary/term/authority management → Tasks 4–5. ✓
• Paginated object list → Task 1 (advances #10); SQL stays in db (two new readers + list_vocabularies). ✓

Placeholder scan: none. <url>/<key> are documented env values. The app2_get helper in Task 5 is described inline.

Type consistency: AdminObjectView/AdminObjectPage/LabelView/Pagination/format_date/parse_date/actor defined in Tasks 1–2 and reused; LabelView imported by admin_vocab/admin_authorities; CreatedId/LabelInput defined in admin_vocab (Task 4) and reused by admin_authorities (Task 5); handlers use the verified db signatures and FieldError/Visibility/AuthorityKind exactly.

Notes for follow-on plans

• Audit vocab/authority/term creation: the db create fns take no AuditActor; add actor + audit when those become security-relevant (file a follow-up).
• #7 (per-user audit actor): object writes now record AuditActor::User; login/logout/auth-event auditing still pending.
• #10 (pagination): object list is paginated; list_field_definitions, list_terms, list_by_kind return all rows (small sets — revisit if they grow).
• #18 (tracing on 500s): these handlers also .map_err(|_| 500); wire tracing alongside the existing public-surface work.
• term/authority value pickers: the UI can now populate Term/Authority flexible fields via these endpoints; a future refinement is a 404 pre-check when adding a term to a non-existent vocabulary (currently a 500 via FK).
• Object-number uniqueness / format: not enforced here; relates to the configurable numbering standard (VISION MVP, separate concern).
