Code Review Complete

I've thoroughly reviewed this PR that fixes delegate column name mapping issues. Here's my comprehensive feedback:

Todo List:

  • Read and understand the main code changes in runtime package
  • Review the new regression tests to understand fixed issues
  • Analyze code quality and potential bugs
  • Check performance considerations
  • Review security implications
  • Assess test coverage
  • Provide comprehensive code review feedback

Summary

This PR addresses critical issues with column name mapping when working with delegate models in ZenStack's polymorphic inheritance system. The changes are well-targeted and fix legitimate bugs around field resolution and selection.

Code Quality & Best Practices ✅

Strengths:

  • Clean, focused changes: The modifications are surgical and address specific delegate handling issues without overhauling the architecture
  • Consistent patterns: The originModel checks follow established patterns throughout the codebase
  • Good defensive programming: Proper null checks and fallback logic in name resolution

Specific improvements:

  • BaseDialect.buildSelectField() (base-dialect.ts:948-954): Now properly handles fields from delegate base models by recursively calling itself with the correct origin model context
  • BaseOperations.buildFieldSelection() (base.ts:218-230): Enhanced to pass originModel for relation selections, ensuring proper model context
  • NameMapper field resolution (name-mapper.ts:117-149): Improved logic handles delegate hierarchy field resolution correctly

Bug Analysis ✅

Issues Fixed:

  1. Delegate field selection errors: Fields from delegate base models weren't being selected with correct model context
  2. Column name mapping failures: When delegates had custom column mappings (@map), the wrong model context was used for name resolution
  3. Relation field resolution: Relations defined in delegate base models weren't resolving properly during selection

No new bugs identified - the changes are defensive and maintain backward compatibility.

Performance Considerations ✅

Positive impacts:

  • Reduced query failures: Fixes prevent runtime SQL errors that would require expensive fallback mechanisms
  • Efficient recursion: The recursive buildSelectField() call is bounded by delegate hierarchy depth (typically shallow)

No performance regressions - the added logic only executes for delegate models and has minimal overhead.

Security Assessment ✅

No security concerns identified:

  • Changes are purely internal to query building logic
  • No user input validation changes
  • No authentication/authorization modifications
  • Field resolution changes maintain proper access control context

Test Coverage Assessment ✅

Excellent test coverage:

  • 15 new regression tests covering various delegate scenarios
  • Real-world scenarios: Tests like issue-1645 cover complex e-commerce polymorphic relationships
  • Edge cases covered: Tests include nested relations, policy interactions, and complex inheritance chains

Key test scenarios:

  • issue-1645: Complex e-commerce delegate model with BaseOrderOrder/GuestOrder inheritance
  • issue-1574: Policy interactions with delegate models (currently skipped - field-level policies not yet supported)
  • Multiple other delegate inheritance patterns

Recommendations

Minor Improvements:

  1. Documentation: Consider adding inline comments explaining the delegate originModel logic in key methods
  2. Error handling: The recursive buildSelectField() could benefit from cycle detection, though delegate cycles should be impossible by design

Code Examples:

The fix in buildSelectField() is particularly elegant:

// Before: Incorrect model context for delegate fields
return query.select(this.eb.ref(`${modelAlias}.${field}`).as(field));

// After: Proper recursive handling for delegate origin models  
return this.buildSelectField(query, fieldDef.originModel, fieldDef.originModel, field);

Verdict: APPROVED

This is a solid fix for legitimate bugs in delegate model handling. The changes are:

  • Well-targeted and surgical
  • Properly tested with comprehensive regression coverage
  • Performance-neutral with security implications
  • Backward compatible

The delegate column name mapping issues were clearly problematic for users working with polymorphic inheritance, and this PR resolves them effectively.

Walkthrough

Replaced direct sql.ref(...) usages with instance-bound expression builder references (this.eb.ref / eb.ref) across CRUD dialects and operations; refactored name-mapper field enumeration and reference handling; removed a test logger usage; and added multiple regression tests for v2-migrated issues.

Changes

Cohort / File(s) Summary
CRUD dialects: ref construction
packages/runtime/src/client/crud/dialects/base-dialect.ts, packages/runtime/src/client/crud/dialects/postgresql.ts
Switched identifier/reference construction from sql.ref(...) to instance expression-builder refs (this.eb.ref / eb.ref) in distinctOn, relation filters, joins and join conditions; adjusted null-check/reference creation sites.
CRUD operations: aggregates, count, update paths

Replaced sql.ref(...) with eb.ref(...) (with occasional as any casts); removed unused sql imports; updated subquery field refs for count/min/max and FK equality in update where-clauses.
Executor name-mapper refactor
packages/runtime/src/client/executor/name-mapper.ts
Switched field enumeration to getModelFields(...), use fieldDef.name for mapping, precompute selections/baseResult merges, and changed unmapped reference handling to return the original node instead of delegating to super.transformReference.
E2E test tweak
tests/e2e/orm/client-api/computed-fields.test.ts

tests/regression/test/v2-migrated/issue-1551.test.ts (1)

4-26: Verify that the test adequately covers the column name mapping fix.

The test loads a schema with delegates and mapped columns (@map('profile_id')), which aligns with the PR objective. However, the test only verifies that the schema can be loaded without errors—it doesn't perform any queries or assertions to confirm that the column name mapping works correctly at runtime with delegates.

Consider whether runtime verification is needed:

  • If issue #1551 was purely a schema generation/compilation error, then loading the schema is sufficient.
  • If the issue involved incorrect SQL generation or runtime query behavior, add assertions that exercise the delegate relationship with mapped columns (e.g., create a User with an IndividualProfile and verify the profile_id mapping works correctly).

Additionally, the test name "verifies issue 1551" is generic. Consider renaming it to describe what's being verified, such as 'delegate with mapped foreign key column'.

tests/regression/test/v2-migrated/issue-1518.test.ts (1)

23-29: Add explicit assertion to verify the record creation.

The test currently relies on implicit assertion (the create operation throws if the bug exists). While this pattern is common for regression tests, adding an explicit verification would make the test more robust and self-documenting.

Consider adding a verification step:

-    await db.taskActivity.create({
+    const created = await db.taskActivity.create({
         data: {
             id: '00000000-0000-0000-0000-111111111111',
             title: 'Test Activity',
             description: 'Description of task',
         },
     });
+
+    expect(created).toMatchObject({
+        id: '00000000-0000-0000-0000-111111111111',
+        title: 'Test Activity',
+        description: 'Description of task',
+    });

Additionally, import expect from vitest:

-import { it } from 'vitest';
+import { expect, it } from 'vitest';
tests/regression/test/v2-migrated/issue-1563.test.ts (1)

1-26: LGTM! Well-structured regression test.

The test correctly verifies the fix for issue 1563 related to column name mapping when delegates are involved. The schema setup with a relation and validation constraint, followed by the update operation, appropriately exercises the code path that was problematic.

Optional enhancement:

Consider adding a brief comment above the test explaining what issue 1563 was about (e.g., "updates failing due to column name mapping with delegates" or similar). This would help future maintainers understand the specific scenario being tested.

tests/regression/test/v2-migrated/issue-1507.test.ts (1)

4-24: Consider expanding test coverage for edge cases.

The test correctly verifies the positive case where auth().age matches a profile's age. Consider adding:

  • A negative test case where auth().age doesn't match any profile (e.g., age: 25) to verify empty results
  • Verification of the returned profile's content (e.g., checking that the returned profile has age: 18)

Example additions:

// Negative case: no match
await expect(db.$setAuth({ id: 1, age: 25 }).profile.findMany()).resolves.toHaveLength(0);
await expect(db.$setAuth({ id: 1, age: 25 }).profile.count()).resolves.toBe(0);

// Verify returned profile content
const profiles = await db.$setAuth({ id: 1, age: 18 }).profile.findMany();
expect(profiles[0].age).toBe(18);
tests/regression/test/v2-migrated/issue-1520.test.ts (1)

4-37: Consider verifying the type discriminator field.

The schema uses @@delegate (type) for polymorphic behavior, but the test doesn't explicitly verify that the type field is correctly set to identify the subtype. While the test focuses on courseId mapping (aligning with the PR's column name mapping fix), confirming the discriminator value would strengthen the regression coverage.

Consider adding a type field check in the assertion:

 expect(r.addedToNotifications).toEqual(
     expect.arrayContaining([
         expect.objectContaining({
             id: 1,
             courseId: 1,
             receiverId: 1,
             senderId: 2,
+            type: 'AddedToCourseNotification',
         }),
     ]),
 );
tests/regression/test/v2-migrated/issue-1562.test.ts (1)

4-22: Well-structured regression test for validation with type composition.

The test correctly sets up a scenario with type inheritance (model User with Base) and validates that the regex constraint is enforced. The schema definition is clear and appropriate for testing the validation behavior mentioned in issue 1562.

Consider adding a brief comment explaining what issue 1562 was about for future maintainers:

+// Issue 1562: Validation should work correctly when fields are defined
+// in models that use type composition (delegates)
 it('verifies issue 1562', async () => {
tests/regression/test/v2-migrated/issue-1506.test.ts (1)

4-4: Document what issue 1506 was and what this test verifies.

Add a comment explaining the original issue and what behavior this test validates. This helps maintainers understand the test's purpose and prevents regressions.

For example:

+// Issue 1506: Policy evaluation failed when accessing related fields through delegates
+// due to incorrect column name mapping in the generated SQL queries
 it('verifies issue 1506', async () => {
tests/regression/test/v2-migrated/issue-1576.test.ts (1)

35-61: Test logic is correct and validates the delegation fix.

The test properly verifies that createManyAndReturn works with delegated models and that the type field is correctly populated. The assertions confirm that both items are created with the expected properties.

Optional: Consider adding explicit count verification.

For additional robustness, you could verify the exact count of returned items:

+    const result = await db.goldItem.createManyAndReturn({
-    await expect(
-        db.goldItem.createManyAndReturn({
             data: [
                 {
                     profileId: profile.id,
                     inventory: true,
                 },
                 {
                     profileId: profile.id,
                     inventory: true,
                 },
             ],
-        }),
-    ).resolves.toEqual(
+        });
+    
+    expect(result).toHaveLength(2);
+    expect(result).toEqual(
         expect.arrayContaining([
             expect.objectContaining({ profileId: profile.id, type: 'GoldItem', inventory: true }),
             expect.objectContaining({ profileId: profile.id, type: 'GoldItem', inventory: true }),
         ]),
     );

This makes it explicit that exactly 2 items should be returned, though the current assertion is sufficient for this regression test.

tests/regression/test/v2-migrated/issue-1627.test.ts (1)

48-48: LGTM!

The assertion correctly validates that without an auth context, the access control policy blocks read access and returns zero results. This effectively tests the column name mapping fix for delegates in policy evaluation.

Optionally, consider adding a complementary positive test case that verifies the access control allows reads when proper auth context is provided:

// Add after line 48
await expect(
    db.$use({ user: { id: '1' } }).gymUser.findMany()
).resolves.toHaveLength(1);

This would provide more comprehensive coverage of the access control behavior.

The removal of testLogger import is a reasonable cleanup that simplifies the test setup. This aligns with potential API changes in the @zenstackhq/testtools alpha version.


6-14: LGTM!

The removal of the testLogger parameter from createPolicyTestClient calls is consistent with the import change and appears to be an API simplification. The test functionality is fully preserved - both regression tests still correctly validate that updating ID fields throws the expected error.

Also applies to: 23-31

tests/regression/test/v2-migrated/issue-1507.test.ts (2)

1-2: LGTM!

Imports are appropriate for a policy-based regression test.


7-10: Verify if the User model is necessary.

The User model is defined but never instantiated or referenced in the test. The $setAuth({ id: 1, age: 18 }) call works without creating an actual User record. Consider removing the User model definition if it's not required for this test case, as it may cause confusion about the test's requirements.

packages/runtime/src/client/crud/dialects/postgresql.ts (1)

234-234: LGTM: Consistent switch to instance-bound expression builder.

The change from sql.ref(left) to this.eb.ref(left) aligns with the PR's objective to fix column name mapping issues for delegate models. Using the instance-bound expression builder (this.eb) instead of the global sql allows proper column resolution and transformations when dealing with polymorphic inheritance hierarchies.

packages/runtime/src/client/crud/operations/base.ts (1)

1543-1545: LGTM: Proper use of callback-scoped expression builder.

The change correctly uses eb.ref(...) where eb is the callback parameter from .where((eb) => ...). This follows Kysely's pattern of using the callback-scoped expression builder for references within query callbacks, ensuring proper column name resolution for delegate models.

packages/runtime/src/client/crud/dialects/base-dialect.ts (1)

105-105: LGTM: Comprehensive and consistent refactor to instance-bound references.

The systematic replacement of sql.ref(...) with this.eb.ref(...) across all query-building paths (distinctOn, filters, joins, orderBy, field selection) is well-executed. This enables proper column name mapping for delegate models by using the instance-bound expression builder, which can apply necessary transformations based on the schema and model context.

The changes are consistent and cover all relevant code paths without altering the query logic.

Also applies to: 251-251, 271-273, 336-336, 356-364, 375-389, 846-862, 951-951

tests/regression/test/v2-migrated/issue-1520.test.ts (2)

1-3: LGTM!

Standard test imports are correctly configured.


39-55: Add assertions confirming inferred courseId and subtype for nested createMany
After creating the course, assert that r.addedToNotifications[0].courseId === r.id and that the notification instance is of type AddedToCourseNotification.

tests/regression/test/v2-migrated/issue-1533.test.ts (2)

4-4: Clarify the TODO comment status.

The TODO mentions "JSON null support", but the test asserts specific behavior for JSON null handling. Please clarify:

  • Is JSON null support now complete and this TODO should be removed?
  • Should this test be marked as skipped or expected to fail until support is complete?
  • Does the TODO refer to additional functionality beyond what this test covers?

5-53: Test structure and logic look good.

The test effectively verifies JSON path queries with both null and string values. The setup creates appropriate test data, and the assertions correctly validate the expected behavior.

Note: This approval is contingent on fixing the missing Prisma import flagged in the previous comment.

tests/regression/test/v2-migrated/issue-1562.test.ts (2)

24-24: Correct validation test logic.

The test correctly validates that a name with spaces ("1 2 3 4") is rejected by the regex pattern ^[a-zA-Z0-9_]{3,30}$, which only allows alphanumeric characters and underscores.


1-2: Custom matcher availability verified—no import needed.
toBeRejectedByValidation is implemented and registered in @zenstackhq/testtools (vitest-ext.ts).

tests/regression/test/v2-migrated/issue-1644.test.ts (1)

1-24: Approve regression test
Field-level policy syntax @allow('read', auth() == this) is valid and consistent with other v2-migrated tests. Test logic and skip annotation are appropriate.

tests/regression/test/v2-migrated/issue-1576.test.ts (1)

1-33: LGTM! Well-structured regression test.

The test setup is clear and appropriate:

  • Schema correctly models delegation using @@delegate(type) for both Profile/GoldProfile and Item/GoldItem hierarchies
  • Relation between Item and Profile via profileId is properly defined
  • Test client creation follows standard patterns

This effectively reproduces the scenario for testing column name mapping with delegates.

tests/regression/test/v2-migrated/issue-1574.test.ts (5)

1-5: LGTM! Appropriate test structure and skip marker.

The imports are correct, and using it.skip with a clear TODO comment is the right approach for tests awaiting feature implementation.


6-52: LGTM! Well-designed schema for policy testing.

The schema effectively tests the interaction between field-level policies (line 22: name field with read-all override) and model-level policies (line 28: owner-only access). The use of both optional (ModelB) and required (ModelC) references to ModelA provides good coverage of different access patterns.


54-67: LGTM! Proper test setup pattern.

The setup correctly uses $unuseAll() to bypass policies during data creation and $setAuth() to create authenticated client instances for each user. This follows the established pattern for policy testing.


69-83: Verify null-safety of nested property access.

Lines 71, 75, and 79 access ref.name directly without null checks. If the query returns null or the ref object is missing, this will throw a TypeError rather than fail the assertion gracefully.

Consider adding optional chaining or explicit null checks:

 const t1 = await db1.modelB.findFirst({ select: { ref: true } });
-expect(t1.ref.name).toBeTruthy();
+expect(t1?.ref?.name).toBeTruthy();

Or assert the parent object first:

 const t1 = await db1.modelB.findFirst({ select: { ref: true } });
+expect(t1.ref).toBeTruthy();
 expect(t1.ref.name).toBeTruthy();

89-95: Verify null-safety of nested property access.

Similar to lines 71, 75, 79, lines 91 and 95 access ref.name directly without null checks, which could throw if ref is missing or null.

Apply the same null-safety pattern as suggested for the earlier assertions.

tests/regression/test/v2-migrated/issue-1627.test.ts (3)

1-2: LGTM!

Standard test imports are correct and appropriate for a regression test using ZenStack testtools and Vitest.


33-46: LGTM!

Test data setup correctly uses $unuseAll() to bypass policies during data creation. The nested create properly establishes the Gym↔GymUser relation, with the foreign key automatically set through the ORM.


4-31: Approve regression test schema
Access rule uses user == auth() syntax consistent with existing tests (issue-689); no change needed.

tests/regression/test/v2-migrated/issue-1522.test.ts (2)

47-85: LGTM!

The test setup and query logic are well-structured for a regression test. The nested create, followed by a separate create for TaskActivity, and then a retrieval with nested includes and consistent ordering (by idx) appropriately exercises the delegate column name mapping scenario described in the PR objectives.


16-43: Explicit @@Allow policies aren’t required for Section, Activity, UrlActivity, or TaskActivity—defaults permit access and this matches other v2-migrated tests.

Code Review Complete

I've thoroughly reviewed this PR that fixes delegate column name mapping issues. Here's my comprehensive feedback:

Todo List:

  • Read and understand the main code changes in runtime package
  • Review the new regression tests to understand fixed issues
  • Analyze code quality and potential bugs
  • Check performance considerations
  • Review security implications
  • Assess test coverage
  • Provide comprehensive code review feedback

Summary

This PR addresses critical issues with column name mapping when working with delegate models in ZenStack's polymorphic inheritance system. The changes are well-targeted and fix legitimate bugs around field resolution and selection.

Code Quality & Best Practices ✅

Strengths:

  • Clean, focused changes: The modifications are surgical and address specific delegate handling issues without overhauling the architecture
  • Consistent patterns: The originModel checks follow established patterns throughout the codebase
  • Good defensive programming: Proper null checks and fallback logic in name resolution

Specific improvements:

  • BaseDialect.buildSelectField() (base-dialect.ts:948-954): Now properly handles fields from delegate base models by recursively calling itself with the correct origin model context
  • BaseOperations.buildFieldSelection() (base.ts:218-230): Enhanced to pass originModel for relation selections, ensuring proper model context
  • NameMapper field resolution (name-mapper.ts:117-149): Improved logic handles delegate hierarchy field resolution correctly

Bug Analysis ✅

Issues Fixed:

  1. Delegate field selection errors: Fields from delegate base models weren't being selected with correct model context
  2. Column name mapping failures: When delegates had custom column mappings (@map), the wrong model context was used for name resolution
  3. Relation field resolution: Relations defined in delegate base models weren't resolving properly during selection

No new bugs identified - the changes are defensive and maintain backward compatibility.

Performance Considerations ✅

Positive impacts:

  • Reduced query failures: Fixes prevent runtime SQL errors that would require expensive fallback mechanisms
  • Efficient recursion: The recursive buildSelectField() call is bounded by delegate hierarchy depth (typically shallow)

No performance regressions - the added logic only executes for delegate models and has minimal overhead.

Security Assessment ✅

No security concerns identified:

  • Changes are purely internal to query building logic
  • No user input validation changes
  • No authentication/authorization modifications
  • Field resolution changes maintain proper access control context

Test Coverage Assessment ✅

Excellent test coverage:

  • 15 new regression tests covering various delegate scenarios
  • Real-world scenarios: Tests like issue-1645 cover complex e-commerce polymorphic relationships
  • Edge cases covered: Tests include nested relations, policy interactions, and complex inheritance chains

Key test scenarios:

  • issue-1645: Complex e-commerce delegate model with BaseOrderOrder/GuestOrder inheritance
  • issue-1574: Policy interactions with delegate models (currently skipped - field-level policies not yet supported)
  • Multiple other delegate inheritance patterns

Recommendations

Minor Improvements:

  1. Documentation: Consider adding inline comments explaining the delegate originModel logic in key methods
  2. Error handling: The recursive buildSelectField() could benefit from cycle detection, though delegate cycles should be impossible by design

Code Examples:

The fix in buildSelectField() is particularly elegant:

// Before: Incorrect model context for delegate fields
return query.select(this.eb.ref(`${modelAlias}.${field}`).as(field));

// After: Proper recursive handling for delegate origin models  
return this.buildSelectField(query, fieldDef.originModel, fieldDef.originModel, field);

Verdict: APPROVED

This is a solid fix for legitimate bugs in delegate model handling. The changes are:

  • Well-targeted and surgical
  • Properly tested with comprehensive regression coverage
  • Performance-neutral with security implications
  • Backward compatible

The delegate column name mapping issues were clearly problematic for users working with polymorphic inheritance, and this PR resolves them effectively.
