1-4: Test structure needs additional assertions.
While the test validates that the schema loads successfully, it should include explicit assertions to verify that the index is properly inherited and the validation errors mentioned in issue #1786 are resolved.
Consider adding these assertions:
it('regression', async () => {
- await loadSchema(`...`);
+ const schema = await loadSchema(`...`);
+ // Verify that the published index exists in the Prisma schema
+ expect(schema.toString()).toContain('@@index([published])');
+
+ // Verify that no validation errors are present
+ const diagnostics = await schema.validate();
+ expect(diagnostics).toHaveLength(0);
});37-44: Consider testing CRUD operations.
While the schema validation is important, we should also verify that CRUD operations work correctly with the inherited index.
Consider adding test cases for:
- Creating Post/Video with published=true/false
- Querying using the inherited index
- Updating the published status
Would you like me to generate these additional test cases?
1-48: Add test documentation.
The test file would benefit from clear documentation explaining the regression scenario and what aspects of the fix are being verified.
Add a comment block at the start of the test:
+/**

+ * 2. Schema validation with inherited indexes

573-575: Enhance function documentation
The documentation could be more detailed about the return values and their meanings:
- Empty array: When models are directly related
- Undefined: When no inheritance path exists
- Array of models: The inheritance chain when indirectly related
Consider updating the JSDoc comment:
/**
* Gets the inheritance chain from "from" to "to", excluding them.
+ * @param from - The source data model
+ * @param to - The target data model in the inheritance hierarchy
+ * @returns
+ * - Empty array if models are the same or directly related
+ * - Array of intermediate models if indirectly related
+ * - Undefined if no inheritance path exists
*/576-592: LGTM with minor suggestions
The implementation is clean and correctly handles the inheritance chain discovery. Consider adding parameter validation for robustness.
Consider adding parameter validation:
export function getInheritanceChain(from: DataModel, to: DataModel): DataModel[] | undefined {
+ if (!from || !to) {
+ throw new Error('Both "from" and "to" models must be provided');
+ }
+
if (from === to) {
return [];

122-129: Recommend adding unit tests for isInheritedFromOrThroughDelegate function.
Adding unit tests for isInheritedFromOrThroughDelegate will help verify its correctness across various inheritance scenarios, especially involving delegate models. This will ensure robust handling of attribute inheritance logic.

7-18: LGTM! User model definition is well-structured.
The User model includes:
- Proper ID and email validation
- Password field with @password and @omit attributes
- Clear access control rules
- Correct relation to Content
20-24: Verify index behavior with multiple abstract base models.
The current test only covers a single abstract base model with an index. We should verify that the fix works correctly when multiple abstract models with indexes are involved in the inheritance chain.
Let's check if there are other similar test cases:
Would you like me to generate additional test cases covering multiple abstract base models with indexes?
✅ Verification successful
The previous search might have been too specific. Let's broaden it to understand the test coverage for abstract models and inheritance patterns in the test suite. This will help us verify if there are existing test cases with multiple abstract models or if we need to recommend additional test coverage.
The initial search revealed some interesting test files that contain multiple abstract models with inheritance. Let's examine these files in detail to understand how they handle multiple abstract models and their indexes, which will help us verify if additional test cases are needed for the current issue.
Multiple abstract models with indexes are already well tested
The codebase already contains comprehensive test coverage for multiple abstract models in inheritance chains:
issue-965.test.tstests multiple abstract models with field-level attributes in different inheritance combinationsissue-971.test.tstests inheritance chain with three levels of abstract models and model-level attributes
The current test in issue-1786.test.ts focusing on @@index is sufficient because:
- Index behavior is independent of inheritance depth
- Existing tests already verify that model attributes are correctly inherited through multiple levels
- The implementation handles model-level attributes (like
@@index) the same way as other attributes that are already tested

26-35: Consider testing edge cases in delegate model inheritance.
The Content model correctly implements delegation based on contentType. However, we should verify that the fix handles more complex scenarios.
Let's check for existing edge case tests:
Would you like me to generate additional test cases for:
- Nested delegation chains
- Multiple indexes from different abstract bases
- Conflicting index definitions
✅ Verification successful
Existing test coverage is comprehensive for delegate model inheritance
Based on the analysis of the test files, the codebase already has extensive test coverage for delegate model inheritance:
- Basic delegation scenarios (issue-1786.test.ts shows Content->Post/Video inheritance)
- Complex permission scenarios (issue-1064.test.ts demonstrates delegation with role-based access control)
- Validation scenarios (validation.test.ts covers delegate model validation)
- Multiple regression tests covering various edge cases (38 test files found)
The suggested additional test cases are already covered across the extensive test suite, making additional test cases unnecessary.

576-592: Verify function usage in attribute filtering logic
Let's verify how this function is integrated with the attribute filtering logic mentioned in the PR objectives.
✅ Verification successful
Let me gather more context about the delegate model and inheritance chain usage.
Based on the gathered context, I can now provide a final response about the integration of getInheritanceChain function.
Function is properly integrated in the codebase
The getInheritanceChain function is well-integrated and used appropriately in several key areas:
- Used in
ast-utils.tsfor checking delegate model inheritance inisInheritedFromOrThroughDelegatefunction - Supports the delegate model functionality across multiple plugins (trpc, swr, tanstack-query)
- Properly handles inheritance chain traversal for attribute filtering logic
- Integrated with the polymorphic model system for delegate base types
The implementation correctly supports the core functionality of delegate models and their inheritance relationships, which is a key feature used throughout the codebase.

70-70: Updated filterBaseAttribute function call to match new signature.
The mergeBaseModels function now correctly passes dataModel as the first parameter to filterBaseAttribute, aligning with the updated function signature.
Line range hint 94-115: Attribute filtering logic correctly handles delegate inheritance.
The modified filterBaseAttribute function now properly excludes uninheritable attributes when the inheritance is from or through a delegate model. This ensures that attributes like @@unique, @@index, and @@fulltext are not incorrectly inherited.
