This improves user experience by allowing reuse of invite links while providing clear feedback on their status and does not treat expired invite links as showstopper - but redirects to login page (with error shown as toast)

This is not a full issue fix because it still allows for adding multiple records to spuserexternalid (issue with compound constrains - would probably need hash of providerid or postgres... see here:

# models.UniqueConstraint(fields=["provider", "providerid"], name="unique_spuser_external_id")
)

Instead, this fix circumvents the issue and treats most common pathway for the issue. That is: New user gets invite link > uses SSO to login and connect the account to SSO > next day user click on the same invite link and complains to admin that they can't log in > admin generates new invite link > user tries to log in with SSO but now there are locked out completly because of MultipleObjectsReturned

In this PR I propose treating expired (and used) links as a minor error and redirect user to standard login page. makes UX more friendly for new users

Fixes #5362

Summary by CodeRabbit

  • Bug Fixes
    • Expired or already-used invitation links now redirect to the login page, where an expiry notice is displayed.
    • When invitation details are invalid during single sign-on, users continue through the regular login flow instead of seeing an error page.

- Simplified the invite token validation logic to only clear the session token after successful user login.
- Updated the response for expired or already-used invite links to redirect to the normal login page with a notice.
- Enhanced the frontend to display an error dialog when an invite link has expired, using consistent messaging.

This improves user experience by allowing reuse of invite links while providing clear feedback on their status.

📝 Walkthrough

Walkthrough

Expired or reused invite links now redirect to the login page with an expiration parameter. The login component clears that parameter and displays a dismissible, localized error dialog. Failed invite validation in the SSO callback continues through normal SSO lookup.

Changes

Invite sign-in

Layer / File(s) Summary
Handle invalid invite tokens
specifyweb/backend/accounts/views.py
The SSO callback continues to normal lookup when invite validation fails. The invite-link endpoint redirects expired or reused links to login with invite_expired=1.
Display invite expiration message
specifyweb/frontend/js_src/lib/components/Login/OicLogin.tsx, specifyweb/frontend/js_src/lib/localization/user.ts
OicLogin detects invite_expired=1, clears the parameter, and displays a dismissible error dialog with the localized invite-expired message.

Full details: Linked Issues check

Explanation

Issue #5362 requires a permanent coding fix for duplicate spuserexternalid records that can block SSO sign-in. The reviewed changes only alter expired or used invite handling. oic_callback still creates spuserexternalid records with .create(...), and normal SSO lookup still uses .get(provider=..., providerid=...), which does not safely handle duplicate records. No duplicate prevention, cleanup, or related automated test is shown.


Full details: Automatic Tests

Explanation

The PR changes authentication control flow and adds a new login error UI, but it adds no automatic tests. The authoritative diff contains only views.py, OicLogin.tsx, and user.ts. The repository has backend test infrastructure and Jest/React Testing Library tests, so these behavior changes require regression coverage.

Resolution

Add backend tests for valid, expired, and already-used invite tokens, including session-token cleanup and fallback to normal SSO. Add a frontend test for invite_expired=1 that verifies the localized ErrorDialog is displayed and the query parameter is cleared.


Full details: Testing Instructions

Explanation

The pull request description contains no testing instructions. The change affects both backend invite/OIC flows and the frontend login dialog, but it does not state how to verify either component. The diff also adds no tests.

Resolution

Add a Testing section with reproducible checks: (1) use a valid invite link, complete OIC login, and verify identity linking and the collection redirect; (2) use an expired invite link and a previously used invite link, verify redirect to /accounts/login/?invite_expired=1, display of the localized dismissible error, removal of the query parameter, and continued normal login; (3) verify that a newer valid invite in the session is not cleared when an older link is opened; and (4) verify the normal non-invite OIC login path. State the required test environment, provider setup, and expected results.

- Replaced hardcoded expired token message with a localized string from userText.
- Ensured consistent messaging in the error dialog for expired invite links, improving user experience.

This change enhances the clarity and maintainability of the code by utilizing localization for user-facing messages.

Thanks so much, @MichalTorma, for contributing! ⭐⭐⭐⭐⭐

I still need to leave #5362 open because duplication is still possible, but this seems like a strong solution for common cases. We can explore enforcing this at a database level and auto-resolving existing cases in another PR.

When you create branches in the future, please use the naming convention issue-5362 so we can easily track which issue each branch aims to solve. This is much appreciated!
