From 693e6420374f1d5800770b7b4d4a338137703c96 Mon Sep 17 00:00:00 2001 From: Samuel Kwong Date: Mon, 8 Jun 2026 07:11:26 +0000 Subject: [PATCH 01/28] docs(reports): spec for ADRF report views refactor Capture the design for replacing the DRF ReportViewSet with three adrf.views.APIView subclasses (list/detail/bulk-upsert), preserving the existing API contract. This is the structural prerequisite for a follow-up PR that triggers the async embedding pipeline from the upload path.

The pipeline itself already runs asynchronously in a Procrastinate worker (`@app.task(queue="embeddings")`), but today it is only kicked off by a periodic `embedding_launcher` cron tick. A follow-up PR will let the upload endpoint enqueue the embedding job directly via `await enqueue_embedding(...)`. + +That follow-up requires the upload endpoints to be async views. DRF's `ViewSet`/`GenericViewSet` are synchronous. ADRF (`adrf` — already installed and listed in `INSTALLED_APPS`) provides async-compatible equivalents. + +This PR is the structural prerequisite: replace the existing DRF `ReportViewSet` with explicit ADRF `APIView` classes, following the same pattern ADIT already uses in `adit/dicom_web/views.py`. No client-visible contract change; no embedding wiring yet. + +## Scope + +**In scope** + +- Drop `radis.reports.api.viewsets.ReportViewSet` and the `DefaultRouter` registration. +- Add three `adrf.views.APIView` subclasses covering all five existing endpoints: + - `ReportListAPIView` — `POST /api/reports/` (create) + - `ReportDetailAPIView` — `GET`/`PUT`/`DELETE` on `/api/reports/{document_id}/` + - `ReportBulkUpsertAPIView` — `POST /api/reports/bulk-upsert/` +- Rewrite `radis/reports/api/urls.py` to wire explicit `path()` entries (no router). +- Keep `_bulk_upsert_reports` (currently in `viewsets.py`) reused as-is; it stays a pure sync function. +- Preserve every existing wire-level behavior: URLs, response shapes, status codes, permission checks (including the `clone_request("POST")` check on PUT-upsert that hits an unknown `document_id`), the `?upsert=` / `?full=` / `?replace=` query parameters, and the 405 for PATCH. +- New test file `radis/reports/tests/test_report_api.py` exercising each endpoint end-to-end via Django's `Client`. +- Preserve existing `radis/reports/tests/test_bulk_upsert.py` (no payload changes needed). Add one assertion confirming the bulk-upsert route still resolves. + +**Out of scope (called out to prevent scope creep)** + +- Wiring the async embedding enqueue from the request path. That is the follow-up PR. +- Touching `ReportSerializer` — it stays sync. +- Converting any other API surface (`radis.search`, `radis.chats`, `radis.extractions`, etc.). +- Migrations, settings, or env-var changes. + +## Decisions and rationale + +### 1. Drop the viewset entirely; follow ADIT's pattern + +We use three explicit `adrf.views.APIView` subclasses wired via `path()` entries rather than `adrf.viewsets`. Reasons: + +- Matches ADIT's `adit/dicom_web/views.py` pattern, which the team already maintains. +- A `DefaultRouter` would still be needed for the viewset variant; explicit paths are simpler and let `bulk-upsert/` and `/` be ordered unambiguously. +- All five endpoints become async with one consistent class hierarchy. No mixed sync/async viewset shape. + +### 2. Hybrid async strategy: native async ORM where clean, `database_sync_to_async` for serializer/transaction blocks + +DRF serializers (`is_valid`, `save`, `data`) are entirely synchronous; ADRF does not change that. Our `ReportSerializer.create`/`update` also use `transaction.atomic()`, which has no native async context manager. So serializer + transactional blocks must be wrapped regardless of how the rest of the view is written. + +We use `channels.db.database_sync_to_async` (rather than `asgiref.sync.sync_to_async`) for any wrapper that touches the database. It's a thin wrapper around `sync_to_async` that additionally closes stale DB connections after the call — the same choice ADIT makes in `adit/dicom_web/views.py`. We only fall back to plain `sync_to_async` for wrappers around code that has no DB interaction. + +For simple, single-call ORM operations that don't cross a serializer or transaction (`get_object_or_404`-style lookups, `report.adelete()`, m2m `aset`), we use the native async ORM methods (`Report.objects.aget(...)`, `await report.adelete()`, etc.). This keeps the diff small and avoids unnecessary thread-pool hops on the read path without complicating the write path. + +Usage map: + +| Endpoint | Native async ORM | `database_sync_to_async`-wrapped block | +| --- | --- | --- | +| `GET /reports/{id}/` | `await Report.objects.select_related("language").aget(...)` | `serializer.data`; each `fetcher.fetch(report)` | +| `PUT /reports/{id}/` | `await Report.objects.aget(...)` (upsert existence check) | `serializer.is_valid` + `serializer.save` + `transaction.on_commit` hookup (one block) | +| `DELETE /reports/{id}/` | `await Report.objects.aget(...)`, `await report.adelete()` | `transaction.on_commit` for `reports_deleted_handlers` | +| `POST /reports/` | — | `serializer.is_valid` + `serializer.save` + `transaction.on_commit` hookup (one block) | +| `POST /reports/bulk-upsert/` | — | per-payload `is_valid` loop + `_bulk_upsert_reports(...)` (one block) | + +### 3. Why we are not subclassing `adrf.serializers.ModelSerializer` + +Examined and rejected. `adrf.ModelSerializer.acreate` calls `raise_errors_on_nested_writes(...)`, which errors out on our nested writable `language` / `metadata` / `modalities` fields. We would have to override `acreate`/`aupdate` ourselves, and to preserve atomicity we would still wrap the body in `@sync_to_async` around a `transaction.atomic()` block. The result is the current sync `create`/`update` verbatim, wrapped in a coroutine — no cleanliness win, just a wrapper layer. `is_valid()` is also still sync in ADRF. + +### 4. API contract is byte-for-byte identical + +- URLs stay `/api/reports/`, `/api/reports/{document_id}/`, `/api/reports/bulk-upsert/`. +- URL `name=`s match what `DefaultRouter` produced today (`report-list`, `report-detail`, `report-bulk-upsert`) so any `reverse()` callers keep working. Grep before merge; adjust if a name diverges. +- Response shapes, status codes, query-param parsing all preserved. +- PATCH still returns 405; this is now achieved by simply not defining `async def patch`, instead of the current explicit `raise MethodNotAllowed`. + +## Module shape + +### `radis/reports/api/urls.py` (rewritten) + +```python +from django.urls import path + +from .views import ( + ReportBulkUpsertAPIView, + ReportDetailAPIView, + ReportListAPIView, +) + +urlpatterns = [ + path("", ReportListAPIView.as_view(), name="report-list"), + path("bulk-upsert/", ReportBulkUpsertAPIView.as_view(), name="report-bulk-upsert"), + path("/", ReportDetailAPIView.as_view(), name="report-detail"), +] +``` + +`bulk-upsert/` is listed before `/` to avoid the path converter swallowing the literal segment. + +### `radis/reports/api/views.py` (renamed from `viewsets.py`) + +Three `adrf.views.APIView` subclasses, each with `permission_classes = [IsAdminUser]`.

PUT-upsert against an unknown id still triggers the `clone_request("POST")` permission check via `get_object_or_none` (re-implemented inside `ReportDetailAPIView.put`). + +## Tests + +Existing: + +- `radis/reports/tests/test_bulk_upsert.py` keeps passing without payload changes.

Test asserts the deleted-handler runs after the delete returns. | +| `serializer.data` access lazy-loads related fields on the thread pool. | Already happens on the request thread today; not a regression. Re-use `select_related("language")` where present. | +| Browsable API root at `/api/reports/` disappears with the router. | Acceptable; this is an admin-only token-auth endpoint, not user-facing.

No migrations, no settings changes, no env vars. +- Verification before opening the PR: + - `uv run cli lint` + - `uv run cli test` + - Manual smoke: `uv run cli compose-up -- --watch`, then `curl` each endpoint with a token and confirm responses match the contract. +- PR description must state explicitly: (a) no API contract change, (b) embedding trigger is **not** added in this PR — that's the follow-up.

Previously, `await report.adelete()` ran on the async connection and the on_commit registration ran on a separate sync connection, so the callback was not bound to the delete's transaction. 2. post / put / bulk-upsert: materialize `request.data` on the async thread (and capture as a local) before entering any `database_sync_to_async` wrapper. Parsing the ASGI body stream from a worker thread risks SynchronousOnlyOperation under ASGI and is the most likely cause of the failing test_report_api / test_bulk_upsert cases in the previous CI run. 3. get (?full=true): replace the sequential per-fetcher `database_sync_to_async` loop with `asyncio.gather`, so multiple document_fetchers run concurrently instead of one-at-a-time.

The first DB query inside the async view (e.g. groups field validation in ReportSerializer) then hits "the connection is closed". Fix: mark every HTTP-based test (and the live_server-based radis-client test) with @pytest.mark.django_db(transaction=True) so pytest-django uses TransactionTestCase semantics (truncate after, no hidden transaction). The two tests that exercise the helpers directly (test_bulk_upsert_dedupes_metadata_keys, test_report_data_valid) keep the default marker.

URL wiring goes back to `DefaultRouter.register("", ReportViewSet, basename="report")`. Why: the legacy class was a `GenericViewSet` + sync mixins; this is the minimum-diff async equivalent. The router-generated URLs, route names (`report-list` / `report-detail` / `report-bulk-upsert`), and default `lookup_value_regex` ([^/.]+) match the legacy contract verbatim, so no test or client change is needed beyond the async-shape guards. The browsable API root at /api/reports/ comes back for free. PATCH still returns 405, now via `http_method_names` instead of an explicit `apartial_update` override. The async-shape guard tests are folded into a single test that pins every dispatched method (acreate / aretrieve / aupdate / adestroy / bulk_upsert) to `inspect.iscoroutinefunction`. The risk this guards is specific to the viewset shape: `adrf.mixins.*ModelMixin` inherits from DRF's sync mixins, so each class has both `create` and `acreate` (etc.) on the MRO; an accidental sync override would silently flip dispatch back to sync.

Drop the viewset entirely; follow ADIT's pattern +### 1. Use `adrf.viewsets.GenericViewSet` + selected mixins + `DefaultRouter` -We use three explicit `adrf.views.APIView` subclasses wired via `path()` entries rather than `adrf.viewsets`. Reasons: +We keep the same shape as the legacy DRF `ReportViewSet`: one class subclassing `adrf.viewsets.GenericViewSet` with the create / retrieve / update / destroy async mixins from `adrf.mixins`, and a `@action(detail=False, methods=["post"], url_path="bulk-upsert")` for the bulk endpoint. URLs are wired through `rest_framework.routers.DefaultRouter`. Reasons: -- Matches ADIT's `adit/dicom_web/views.py` pattern, which the team already maintains. -- A `DefaultRouter` would still be needed for the viewset variant; explicit paths are simpler and let `bulk-upsert/` and `/` be ordered unambiguously. -- All five endpoints become async with one consistent class hierarchy. No mixed sync/async viewset shape. +- **Minimum structural diff vs. legacy.** The old class is `mixins.CreateModelMixin / DestroyModelMixin / RetrieveModelMixin / UpdateModelMixin + GenericViewSet`. The new one is the `adrf.mixins` equivalents + `adrf.viewsets.GenericViewSet`. A reviewer can read the diff as "convert sync mixins to async mixins" without re-learning a different architecture. +- **Router-generated URLs match the legacy contract for free.** `DefaultRouter` produces the same paths (`/api/reports/`, `/api/reports/{document_id}/`, `/api/reports/bulk-upsert/`) and the same route names (`report-list`, `report-detail`, `report-bulk-upsert`) the legacy code emitted, with no manual `path()`/`re_path()` work. `lookup_value_regex` defaults to `[^/.]+`, which is exactly the document-id constraint we need. +- **Browsable API root at `/api/reports/` is preserved.** `DefaultRouter` automatically adds an HTML index view there, matching legacy behavior. No regression for anyone navigating with a browser. +- **One async dispatch decision per class.** ADRF's `view_is_async` flips the entire viewset to the async dispatch path as soon as any method on it is a coroutine. Once we define `acreate`/`aretrieve`/`aupdate`/`adestroy` + the `async def bulk_upsert` action, every entry point is async. There's no per-URL flip-flopping between sync and async. + +**Trade-off accepted:** `adrf.mixins` define both sync `create`/`retrieve`/`update`/`destroy` (inherited from DRF) *and* their async `a*` siblings. Our overrides target the `a*` versions; the sync versions remain on the class but are not dispatched (because `view_is_async` is True). The risk is that a future contributor sees the sync `create()` method on the inheritance chain and "fixes" it without realising the async version is what runs.

Behaviour is unchanged from the previous viewset commit (7215e2f9). CI on that commit was green; the file moves here are import-path only and should keep CI green.

Reasons: +We keep the same shape as the legacy DRF `ReportViewSet`: one class subclassing `adrf.viewsets.GenericViewSet` with the create / retrieve / update / destroy async mixins from `adrf.mixins`, and a `@action(detail=False, methods=["post"], url_path="bulk-upsert")` for the bulk endpoint. URLs are wired through `adrf.routers.DefaultRouter` (NOT `rest_framework.routers.DefaultRouter` — see below). Reasons: - **Minimum structural diff vs. legacy.** The old class is `mixins.CreateModelMixin / DestroyModelMixin / RetrieveModelMixin / UpdateModelMixin + GenericViewSet`. The new one is the `adrf.mixins` equivalents + `adrf.viewsets.GenericViewSet`. A reviewer can read the diff as "convert sync mixins to async mixins" without re-learning a different architecture. - **Router-generated URLs match the legacy contract for free.** `DefaultRouter` produces the same paths (`/api/reports/`, `/api/reports/{document_id}/`, `/api/reports/bulk-upsert/`) and the same route names (`report-list`, `report-detail`, `report-bulk-upsert`) the legacy code emitted, with no manual `path()`/`re_path()` work. `lookup_value_regex` defaults to `[^/.]+`, which is exactly the document-id constraint we need. - **Browsable API root at `/api/reports/` is preserved.** `DefaultRouter` automatically adds an HTML index view there, matching legacy behavior. No regression for anyone navigating with a browser. - **One async dispatch decision per class.** ADRF's `view_is_async` flips the entire viewset to the async dispatch path as soon as any method on it is a coroutine. Once we define `acreate`/`aretrieve`/`aupdate`/`adestroy` + the `async def bulk_upsert` action, every entry point is async. There's no per-URL flip-flopping between sync and async. +**Router choice is load-bearing.** DRF's `DefaultRouter` maps HTTP methods to the sync action names (`POST → create`, `PUT → update`, etc.). Because `adrf.mixins.*` inherit from DRF's sync mixins, those sync method names exist on the class, so DRF's router silently dispatches to the inherited sync mixin implementations — *not* our `acreate`/`aretrieve`/`aupdate`/`adestroy` overrides. `adrf.routers.DefaultRouter` rewrites the action mapping to the `a`-prefixed names whenever `view_is_async=True`, so dispatch hits our overrides. The async-shape guard test catches the override identity, but it cannot catch a mis-wired router; we treat the router choice as part of the architectural contract. + **Trade-off accepted:** `adrf.mixins` define both sync `create`/`retrieve`/`update`/`destroy` (inherited from DRF) *and* their async `a*` siblings. Our overrides target the `a*` versions; the sync versions remain on the class but are not dispatched (because `view_is_async` is True). The risk is that a future contributor sees the sync `create()` method on the inheritance chain and "fixes" it without realising the async version is what runs. We mitigate with an explicit module docstring and the async-shape guard tests (described under Tests). ### 2.

Changes: - bulk_upsert_reports is now `async def`. Preflight (Language / Modality dedupe + ensure-exists, plus the existing-Reports lookup) uses native async ORM. The atomic write block (Phase 4) is a nested sync helper with the new decorator stack. - acreate / aupdate / adestroy switched from `database_sync_to_async def _x()` to `@sync_to_async(thread_sensitive=True) @transaction.atomic def _x()`. adestroy no longer needs the explicit `with transaction.atomic` inside the body — the decorator does it. - aretrieve's serializer.data + fetcher fetches switch to plain sync_to_async(..., thread_sensitive=True) (no atomic needed). - The bulk_upsert action splits per-payload DRF validation (sync, no atomic) from the now-async bulk_upsert_reports call. - test_bulk_upsert_dedupes_metadata_keys becomes async to call the now-async bulk_upsert_reports. Caveat documented in the module docstring: Django 6.0/6.1's native async ORM methods (aget, abulk_create, ...) still wrap sync_to_async internally — there is no native async DB backend in Django today (PR #17275 stalled since 2024). The Phase 2 native async preflight in bulk_upsert_reports does not parallelize at the DB layer today; the win is architectural clarity. When Django ships native async DB support, the code shape is positioned to benefit automatically.

Decorating the outer `_create` / `_save` helpers with another `@transaction.atomic` opened a redundant outer transaction whose only inner work was a savepoint from the serializer's own block — functionally a no-op but misleading about who owns atomicity at each layer. Remove the decorator from `acreate._create` and `aupdate._save`. The `transaction.on_commit(...)` registration following `serializer.save()` in those helpers now runs outside any active transaction in production (serializer.save committed already) and fires immediately — same end-state as before, just without claiming ownership we don't have. `adestroy._delete_and_schedule` keeps `@transaction.atomic` because the `report.delete()` + `transaction.on_commit` registration must be bound to the same transaction (Gemini's original review fix). `bulk_upsert_reports._do_atomic_writes` keeps it because the multi-row churn must commit atomically.

Files: - New `radis/reports/api/operations.py`: - `create_report_from_validated(validated_data)` — creates a Report + Language/get-or-create + groups + Metadata bulk + Modalities/get-or-create via native async ORM. - `update_report_from_validated(report, validated_data)` — replaces all mutable fields + nested associations (metadata delete + recreate, modalities aclear+aset, groups aset). - `delete_report(report)` — `await report.adelete()`. None of these own a transaction; the caller does. - `radis/reports/api/serializers.py`: - `ReportSerializer.create` / `.update` are sync shims that delegate to `async_to_sync(operations.*_report_from_validated)`. DRF's standard `serializer.save()` works unchanged for any future caller; the `with transaction.atomic():` block formerly owned by the serializer is gone — atomicity moves up to the view's helper where it belongs. - `radis/reports/api/viewsets.py`: - `acreate` / `aupdate` re-add `@transaction.atomic` on the sync_to_async helper now that the serializer no longer owns atomicity. The helper body is just `serializer.is_valid` + `serializer.save()` + `transaction.on_commit(...)`. - `adestroy` replaces the bare `report.delete()` call inside the atomic helper with `async_to_sync(operations.delete_report)(report)`, matching the pattern across the file. - Phase 4 of `bulk_upsert_reports` keeps inline sync ORM (bulk_create / bulk_update / through-table churn) because those are already single-statement bulk operations; decomposing them into per-entity async ops would be noise. The pattern applies uniformly to single-entity write paths. - Module docstring updated to describe the operations.py + async_to_sync architecture.

The sync `create`/`update` shims that wrapped operations in async_to_sync are replaced by native `async def acreate`/`aupdate` that `await` the operations directly: async def acreate(self, validated_data): return await operations.create_report_from_validated(validated_data) async def aupdate(self, report, validated_data): return await operations.update_report_from_validated(report, validated_data) The view's atomic helpers now bridge to the async serializer via `async_to_sync(serializer.asave)()` inside the `@sync_to_async(thread_sensitive=True) @transaction.atomic` block. Net bridge count is unchanged (the `async_to_sync` simply moved from inside the serializer up to the view's atomic helper) but two things get cleaner: - The serializer reads as native async — no sync shim importing `async_to_sync` purely to bridge back to an async operation. - Async callers (notably the forthcoming inline-embedding flow that awaits the embedding client) can `await serializer.asave()` directly, eliminating a double bridge (async → sync_to_async → sync → async_to_sync → async) that the sync-shim version would have required. Other changes: - `cast(ReportSerializer, self.get_serializer(...))` is used inside the view's atomic helpers so pyright resolves `.asave` against the actual ADRF type rather than DRF's `BaseSerializer` stub. - `serializers.py` imports `operations` at module scope (no longer needs a function-scope import for the bridge). - `serializers.py` drops the now-unused `async_to_sync` import.

The 2 extra bridges are sync_to_async hops with µs-level dispatch overhead, negligible against the SQL latency they straddle. The win is that the serializer reads as the unit that owns "save + its transaction", and the view reads as pure orchestration around an async-native serializer that can be awaited directly by future async callers (notably the forthcoming inline-embedding flow). `adestroy` and `bulk_upsert_reports` keep their existing `@sync_to_async @transaction.atomic` shape because neither involves a serializer.

Wrap them both in `@sync_to_async(thread_sensitive=True)` helpers so they execute on the asgiref thread pool and the event loop stays free. - Phase 1 (`_dedupe_payload`) — dedupes the input payload by `document_id` and emits a warning on duplicates. Returns the deduped list back to the outer scope. - Phase 3 (`_build_report_lists`) — iterates the validated payload, builds the `new_reports` / `updated_reports` lists using `language_by_code` and `existing_by_document_id` from Phase 2. Returns the four collections back to the outer scope. `report_field_names` is hoisted above Phase 1 since both Phase 3 and Phase 4 reference it. The dedupe helpers (`_dedupe_by_key`, `_dedupe_metadata`, `_dedupe_groups`) move inside `_do_atomic_writes` because that's their only call site, keeping the outer scope clean. Performance note (documented in the module docstring): there's no real wall-clock benefit today because Django's `aget`, `abulk_create` and friends are still `sync_to_async`-wrapped sync ORM internally, so Phase 2's "native async" path schedules on the same thread pool as Phases 1/3/4. The win is purely structural: event loop stays free of CPU work, and the code reads as "async coordination dispatching CPU work to threads", which composes correctly the moment Django ships native async DB support.
