Summary

  • Add per-user favorite support for charts and dashboards — previously the star toggle only lived in frontend state and reset on every refresh
  • New ChartFavorite / DashboardFavorite models (per-user, unique per chart/dashboard) with migration 0170_chart_dashboard_favorites
  • New endpoints: POST/DELETE /api/charts/{id}/favorite/ and POST/DELETE /api/dashboards/{id}/favorite/
  • is_favorite added to ChartResponse/DashboardResponse, computed only on list_charts/list_dashboards (the only consumers) — get_chart, update_chart, get_dashboard, update_dashboard intentionally don't compute it, keeping the change scoped to what's actually used
  • Favorite state is scoped per user via OrgUser, verified against Superset's own FavStar model for consistency with how favoriting works elsewhere

Summary by CodeRabbit

  • New Features

    • Added the ability to favorite and unfavorite charts and dashboards.
    • Chart and dashboard listings now show each item’s favorite status.
    • Favorite actions are user-specific and safely handle repeated requests.
    • Missing charts or dashboards return a not-found response.
    • Favorites are automatically removed when their chart or dashboard is deleted.
  • Tests

    • Added coverage for favorite status, user isolation, idempotency, deletion cleanup, and error handling.

Walkthrough

Changes

Chart and dashboard APIs now support per-user favorites. A shared model and service persist favorites. Listing responses include is_favorite. POST and DELETE endpoints support idempotent changes with authorization and error handling. Resource deletion removes related favorites.

Per-user favorites

Layer / File(s) Summary
Favorite persistence model
ddpui/models/favorite.py, ddpui/migrations/0177_favorite.py
Adds chart and dashboard resource types, the Favorite model, indexes, and a uniqueness constraint.
Favorite services and response contracts
ddpui/services/favorite_service.py, ddpui/services/chart_service.py, ddpui/services/dashboard_service.py, ddpui/schemas/chart_schemas/crud.py, ddpui/schemas/dashboard_schema.py
Adds favorite storage operations, organization checks, favorited-ID lookups, deletion cleanup, and is_favorite response fields.
Favorite API integration and validation
ddpui/api/charts_api.py, ddpui/api/dashboard_native_api.py, ddpui/tests/api_tests/test_charts_api.py, ddpui/tests/api_tests/test_dashboard_native_api.py
Adds favorite endpoints and listing state. Tests cover idempotency, error responses, user isolation, serialization, and deletion cleanup.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🟠 High · up to 8e7be

The change can create orphaned favorite records during concurrent deletion and may allow a user to add or remove favorites across organizations when organization and user context differ. These are concrete data-integrity and tenant-isolation risks that should be fixed before merge.

If i delete a chart then it won't delete the rows in ths table right ? Same with the dashboard too.
Is this the correct design choice ?

Correct, it should be like what you are suggesting. Updated, thanks
Now, when deleting the chart/dashboard, entry for that chart/dashboard will also be removed from the favorite table

363-364: 🔒 Security & Privacy | 🟠 Major | ⚡ Quick win

Enforce the orguser and org tenant invariant.

These methods validate the chart against org, but they write a Favorite for orguser without checking that orguser.org_id == org.id. A caller with mismatched arguments can create or remove a cross-organization favorite association.

Derive the organization from orguser, or reject mismatched arguments. If you raise ChartPermissionError, also map it to HTTP 403 in the chart favorite endpoints.

Serialize favorite creation with resource deletion.

favorite_chart and favorite_dashboard validate the resource, then insert the Favorite row without a transaction. A concurrent deletion can remove the resource and its favorites before this insert, leaving an orphan because resource_id has no foreign key.

Wrap favorite creation and cleanup in transaction.atomic(). Lock the resource row with select_for_update() in both favorite and deletion flows, including single and bulk chart deletion and dashboard deletion.
