WalkthroughThis pull request introduces significant changes to data management and deletion strategies across multiple components of the application. The modifications primarily focus on simplifying database operations related to deletions, removing explicit cascading deletion logic, and leveraging Prisma's built-in referential integrity features. The changes span API routes, tRPC routers, and the database schema, aiming to streamline how related entities are handled during deletion processes. Changes

96-139: Well-structured foreign key constraints with appropriate deletion behaviors.The foreign key constraints are well-designed with:
- CASCADE deletion for strong parent-child relationships
- SET NULL for optional relationships (e.g., subscriptions, event references)
Consider documenting these relationship behaviors in your API documentation or README, as they represent important business rules about data lifecycle management. For example:
- When a user is deleted, all their data (polls, comments, etc.) is automatically removed
- When an event is deleted, associated polls remain but lose their event reference

120-151: Consider deprecating the 'closed' field.The model looks well-structured, but there's a deprecated 'closed' field alongside the new 'status' enum. Consider removing the deprecated field in a future migration.
- closed Boolean @default(false) // @deprecated

1-77: LGTM! Comprehensive cleanup of orphaned records.
The cleanup operations are well-structured and handle all related entities in a logical order. The validation against parent tables ensures referential integrity.
Let's verify if there are any remaining orphaned records after the migration:
78-95: Index changes align with the new foreign key constraints.
The removal of redundant indexes and recreation of the guest_id index is appropriate, as foreign key constraints will automatically create indexes.
Let's verify the index changes and their impact on query performance:
✅ Verification successful
Index changes are correctly aligned with foreign key constraints
The verification confirms that the index changes are appropriate:
-
The dropped indexes (
accounts_user_id_idx,comments_user_id_idx,polls_user_id_idx,watchers_user_id_idx) are now covered by their corresponding foreign key constraints:accounts_user_id_fkeycomments_user_id_fkeypolls_user_id_fkeywatchers_user_id_fkey
-
The
polls_guest_id_idxis correctly recreated as it's not covered by any foreign key constraint (guest_id is not a foreign key) and is needed for efficient guest user queries.

The following scripts were executed for the analysis:

Line range hint 33-62: LGTM! Appropriate relationship behaviors for User-related models.
The changes properly define:
- Cascade deletion for dependent Account records
- Bidirectional User-Participant relationship
- Null handling for optional Subscription relationship
Line range hint 158-203: LGTM! Consistent relationship behaviors and proper indexing.
The models demonstrate:
- Appropriate cascade deletions for dependent relationships
- Null handling for optional user references
- Efficient Hash-type indexes for foreign keys
Line range hint 209-245: LGTM! Well-structured Option and Vote models with proper constraints.
The implementation includes:
- Appropriate cascade deletions ensuring referential integrity
- Comprehensive indexing strategy for efficient queries
- Clear relationship definitions
259-261: LGTM! Proper relationship behaviors for Comment model.
The implementation correctly handles:
- Cascade deletion for poll-dependent comments
- Cascade deletion for user-authored comments
- Optional user relationship
