What was wrong

Applying a role template returned 400 on PROD. ApplyTemplate.cshtml used its own raw fetch() helper instead of viperFetch, so the POST carried no X-CSRF-TOKEN and CustomAntiforgeryFilter rejected it. The helper also discarded error responses, so the failure was silent. This broke when CSRF validation landed (VPR-38); #308 never touched this file.

Changes

  • Everything routes through viperFetch, which attaches the token and surfaces failures. Success confirms with a toast, only when every write in the run lands.
  • Preview GET returns 200 with a null result for an unknown member instead of 404, so "no such user" is distinguishable from a failed read. The POST still 404s.
  • Apply may only act on the set the table shows. Previews are versioned so a slow one cannot land over a newer one, Apply stays disabled while a preview or a run is in flight, and a preview whose read failed is discarded whole rather than leaving a partial table to act on.
  • A failed VMACS push no longer reports success. VMACS returns its verdict inside a 200, so result.success is the real outcome, not the status code.
  • Reject an empty role list at Roles/Members/VMACSExport. It was read as "no filter", exporting every user in the instance and skipping the per-role access check. Reachable from two views.
  • URL-encode ids and the search term; trim pasted login-id lists.

Verified

Unit tests pin the new contracts: 200-with-null previews, instance-scoped template access, Ok(null) surviving the response wrapper, and the empty-role-list rejection.

In the browser, against the Tester accounts: apply returns 204 and confirms; multiple login ids send one POST each; a forced preview race discards the stale result; a blocked template read leaves Apply disabled and fires no POST; failed writes show the server's message with no toast. VMACS pushes from dev and TEST go to QA, not production, and a real QA push surfaced its error correctly with no success toast.

Pull request overview

Fixes PROD 400s when applying a RAPS role template by routing writes through viperFetch so CSRF headers are attached and failures are surfaced consistently, while also tightening the preview/apply targeting logic and adjusting the preview endpoint contract to support “no match” as a normal response.

Changes:

  • Replace the Razor view’s raw fetch() helper with viperFetch, add URL-encoding + trimmed pasted login-id handling, and unify preview/apply target selection.
  • Change the preview endpoint to return 200 OK with a null result for “unknown member” (keeping the apply POST behavior unchanged).
  • Add new unit tests covering the preview contract and ensuring Ok(null) preserves "result": null through the API response wrapper.

File Description
web/Areas/RAPS/Views/Roles/ApplyTemplate.cshtml Uses viperFetch for POSTs (CSRF), shares preview/apply targeting, encodes inputs, and adds success toast gating.
web/Areas/RAPS/Controllers/RoleTemplatesController.cs Returns Ok(null) for unknown-member previews to avoid treating “no match” as an error on the client.
test/RAPS/RoleTemplatesControllerTests.cs New tests covering preview behavior, instance scoping, and unknown-member apply behavior.
test/Classes/ApiResponseAttributeTests.cs Adds coverage to ensure Ok(null) keeps an explicit "result": null in JSON.

📝 Walkthrough

Walkthrough

Changes

The preview endpoint returns HTTP 200 with a null result for unknown members. The Apply template view supports selected users and multiple login IDs, coordinates preview requests, applies each target, and handles VMACS push results. VMACS export rejects empty role lists.

Role template flow

Layer / File(s) Summary
Preview response contract
web/Areas/RAPS/Controllers/RoleTemplatesController.cs, test/Classes/ApiResponseAttributeTests.cs
Unknown preview members return a successful response with an explicit result:null payload. Write requests still return NotFound.
Target selection and application flow
web/Areas/RAPS/Views/Roles/ApplyTemplate.cshtml
The view resolves selected users or trimmed login IDs, applies the template to each target, prevents stale preview results from overwriting newer results, and reports VMACS failures.
Role-template controller validation
test/RAPS/RoleTemplatesControllerTests.cs
Tests cover unknown targets, known-member role flags, login-ID resolution, invalid templates, cross-instance access, and unknown-member writes.
VMACS export input validation
web/Areas/RAPS/Controllers/RoleMembersController.cs, web/Areas/RAPS/Views/Permissions/Roles.cshtml, test/RAPS/RoleMembersControllerTests.cs
The controller rejects empty role ID lists and non-VMACS instances. The view skips empty export requests. Tests cover both controller rejection cases.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: ⚪ Minimal · up to 35099

The change ensures role-template writes include CSRF protection, surfaces failed operations, and prevents stale or failed previews from enabling an unintended apply. No actionable merge-blocking risk remains after normal checks and review.

Applying a template to a user POSTed without the X-CSRF-TOKEN header, so
CustomAntiforgeryFilter rejected every apply with a 400. The page swallowed
the response, leaving no sign the write had failed.

- Replace the local raw-fetch send() helper with viperFetch, which attaches
  the token and surfaces failures
- Confirm a successful apply with a status toast, only when every write in
  the run landed, including the VMACS push whose outcome arrives inside a
  200 rather than in the status code
- Reject an empty role list at the VMACS export endpoint, which read it as
  "no filter" and answered by exporting every user in the instance while
  skipping the per-role access check
- Version each preview and block applying until the current one finishes, so
  a slow earlier preview cannot leave the table describing a different user
  than the button writes to
- Discard the whole preview when any read fails, so Apply is never offered
  against a set of users the table did not show for review
- Return 200 with a null result when a preview matches no member, so the
  page can tell "no such user" from a read that failed
