Summary by CodeRabbit

  • Bug Fixes

    • Standardized relation count construction so filtered _count results are accurate.
    • Corrected default and generated value application by using field definitions directly.
    • Validation tightened for JSON-typed attribute defaults (requires string in the specific JSON-default case).
    • Prevents creating unique constraints that mix inherited fields with new ones.
  • Tests

    • Added regression tests covering composite uniques, auth-dependent defaults, JSON defaults/persistence, BigInt, filtered relation counts, and complex access rules.

Walkthrough

Adds a Typed JSON default validation special-case, standardizes relation count query construction via a model-select builder, switches default/generated value handling to use field definitions, avoids creating unique constraints that reference inherited fields, and adds several regression tests covering related behaviors.

Changes

Cohort / File(s) Summary of Changes
Language validator
packages/language/src/validators/attribute-application-validator.ts
Adds a special-case in assignableToAttributeParam: when destination is ContextType on a DataField that is Typed JSON and the attribute is @default, require the argument resolved type to be String; imports hasAttribute to perform the check.
Runtime — CRUD dialect (relation counts)
packages/runtime/src/client/crud/dialects/base-dialect.ts
Replaces direct selectFrom(...) uses with buildModelSelect(...) when constructing relation count queries; casts field types to model generics and removes the previous inline _count filter merge logic while preserving joins and count selection.
Runtime — Operations (defaults/generated values)
packages/runtime/src/client/crud/operations/base.ts
Replaces lookups from fields[...] with direct fieldDef usage in fillGeneratedAndDefaultValues, applying transformations using fieldDef.type/fieldDef.array and adjusting updatedAt/default logic accordingly (including JSON default handling).
Runtime — Schema DB pusher
packages/runtime/src/client/helpers/schema-db-pusher.ts
In addUniqueConstraint, skip single-field and multi-field unique constraints when any involved field is inherited from a different origin model.
Regression tests
tests/regression/test/v2-migrated/*
Adds tests: issue-2028.test.ts (compound unique + inheritance), issue-2038.test.ts (auth-driven default on create), issue-2039.test.ts (JSON defaults persistence), issue-2106.test.ts (BigInt create), issue-2246.test.ts (includes and _count with filters), issue-2247.test.ts (ACL with nested relations).

Poem

I hop through fields and tiny quirks,
Making defaults obey the perks.
I count relations with builder grace,
Keep inherited constraints out of place.
Tests cheer loud — a speedy race! 🐇✨

  • Analyze regression test coverage
  • Provide comprehensive feedback

🔍 Code Review Summary

Quality Assessment: Good ⭐⭐⭐⭐

Strengths

  1. Comprehensive Bug Fixes: The PR addresses multiple specific issues (2028, 2038, 2039, 2106, 2246, 2247) with targeted fixes
  2. Excellent Test Coverage: Each fix includes a corresponding regression test that reproduces the original issue
  3. Clean Code Organization: Changes are well-organized across the appropriate modules (language validation, runtime operations, schema handling)
  4. Type Safety Improvements: Several improvements to type casting and handling in base-dialect.ts:994

🔧 Key Changes Analysis

1. Language Validator Fix (attribute-application-validator.ts)

  • Issue: JSON field default value validation
  • Fix: Added proper type checking for @json fields with @default attribute
  • Quality: ✅ Good - Proper type validation with clear logic

2. Delegate Count Relations (base-dialect.ts)

  • Issue: Count queries not properly filtering delegate relations
  • Fix: Changed from simple selectFrom to buildModelSelect to handle delegate hierarchy and filters
  • Quality: ✅ Excellent - More robust approach that properly handles complex delegate scenarios

3. Default Value Generation (base.ts:816-856)

  • Issue: Inconsistent field access in default value processing
  • Fix: Consistent use of fieldDef variable instead of accessing fields[field]
  • Quality: ✅ Good - Better consistency and type safety

4. Schema DB Constraints (schema-db-pusher.ts)

  • Issue: Unique constraints incorrectly applied to inherited delegate fields
  • Fix: Skip unique constraints for fields inherited from base models
  • Quality: ✅ Good - Prevents SQL constraint conflicts in delegate hierarchies

🧪 Test Coverage Analysis

All 6 regression tests are well-written and cover:

  • Issue 2028: Compound unique filters with delegate models
  • Issue 2038: Boolean default values with auth context
  • Issue 2039: JSON default values for custom types
  • Issue 2106: BigInt type handling
  • Issue 2246: Delegate model count queries with filters
  • Issue 2247: Complex nested delegate policy expressions

⚠️ Minor Concerns

  1. Type Casting: Line 994 in base-dialect.ts has an explicit cast to GetModels<Schema> - while functional, consider if this indicates a broader type issue
  2. Error Handling: The changes don't add additional error handling, though the existing patterns appear sufficient

🔒 Security Review

  • ✅ No security concerns identified
  • ✅ Proper authentication context handling in default values
  • ✅ No SQL injection risks from the changes

Performance Considerations

  • ✅ The buildModelSelect change in delegate count queries is more efficient than the previous approach
  • ✅ Proper filtering prevents unnecessary constraint creation
  • ✅ No performance regressions expected

📋 Recommendations

  1. Minor: Consider adding a comment explaining why the type cast is necessary in base-dialect.ts:994
  2. Future: The delegate model handling could benefit from more comprehensive documentation given its complexity

💯 Overall Assessment

This is a solid bug-fix PR that demonstrates good engineering practices:

  • Targeted fixes for specific issues
  • Comprehensive regression test coverage
  • Clean, maintainable code changes
  • No breaking changes or security concerns

Recommendation: ✅ Approve and Merge

The fixes are well-implemented and the regression tests provide confidence that these issues won't resurface.

Comments suppressed due to low confidence (1)

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

  • This path changes _count logic for many-to-many relations by switching to buildModelSelect (which applies filters/policies). There is no test here exercising _count with where filters on M2M relations; please add a regression test that covers M2M relation counting with a where clause to ensure filtering is correctly applied post-change.

🧹 Nitpick comments (7)
tests/regression/test/v2-migrated/issue-2106.test.ts (2)

4-13: Consider querying back the created record.

The test creates a User with a BigInt field but doesn't verify that the value was persisted and can be retrieved correctly. Consider adding a query to fetch the created record and assert that the age field contains the expected BigInt value.

Example:

     const db = await createTestClient(
         `
 model User {
     id Int @id
     age BigInt
     @@allow('all', true)
 }
             `,
     );
 
-    await expect(db.user.create({ data: { id: 1, age: 1n } })).toResolveTruthy();
+    const created = await db.user.create({ data: { id: 1, age: 1n } });
+    expect(created).toBeTruthy();
+    
+    const retrieved = await db.user.findUnique({ where: { id: 1 } });
+    expect(retrieved?.age).toBe(1n);

15-15: Optional: Add a descriptive comment about the issue.

Consider adding a brief comment explaining what bug issue 2106 addresses. This helps future maintainers understand the purpose of the test.

Example:

+// Issue 2106: Verify that BigInt fields can be created without errors
 await expect(db.user.create({ data: { id: 1, age: 1n } })).toResolveTruthy();
tests/regression/test/v2-migrated/issue-2038.test.ts (2)

7-11: Consider adding a default value to User.flag.

While not required for this specific test, adding a default value to the flag field would make the schema more robust and prevent potential issues if users are created elsewhere in the test suite.

 model User {
     id Int @id @default(autoincrement())
-    flag Boolean
+    flag Boolean @default(false)
     @@allow('all', true)
 }

4-24: Consider adding edge case coverage.

The current test verifies the happy path where auth().flag is true. To improve robustness, consider adding test cases for:

  • auth().flag is false
  • No auth context is set
  • Auth context exists but flag is undefined

This would provide more comprehensive coverage of the auth-driven default behavior.

tests/regression/test/v2-migrated/issue-2246.test.ts (1)

48-56: Assert the included relation content

Right now the test only checks that findMany returns one director. If the regression we’re guarding against caused the movies include to ignore its where filter (or return an empty array), this assertion would still pass because there’s only one director in the fixture. Please assert the filtered include result so the test actually fails when the relation isn’t filtered as expected.

-    await expect(
-        db.director.findMany({
-            include: {
-                movies: {
-                    where: { title: 'Inception' },
-                },
-            },
-        }),
-    ).resolves.toHaveLength(1);
+    const directors = await db.director.findMany({
+        include: {
+            movies: {
+                where: { title: 'Inception' },
+            },
+        },
+    });
+    expect(directors).toHaveLength(1);
+    expect(directors[0]?.movies).toHaveLength(1);
+    expect(directors[0]?.movies[0]?.title).toBe('Inception');
tests/regression/test/v2-migrated/issue-2247.test.ts (2)

4-4: Consider adding a descriptive comment explaining what's being tested.

The test name "verifies issue 2247" is generic. Since this is a regression test for a specific fix related to delegation and relation count queries, consider adding a comment that explains what behavior from issue 2247 is being verified (e.g., "verifies that relation count queries with @@DeleGate don't crash" or similar).

Example:

+// Regression test for issue 2247: verifies that relation count queries
+// with @@delegate(placeType) and nested relation filters resolve successfully
 it('verifies issue 2247', async () => {

59-60: Consider whether test data should be added to exercise access control rules.

The test verifies that the query resolves successfully (which is appropriate for a regression test if the original issue was a crash or error). However, without creating any test data:

  • The access control rules on lines 50-54 aren't meaningfully exercised
  • thing.findMany() will return an empty array, which still passes toResolveTruthy() since [] is truthy

If the intent is solely to verify that delegation + relation count queries compile and execute without errors, the current test is sufficient. However, if the access control filtering logic should also be verified, consider adding test data setup.

Example with data setup:

const authDb = db.$setAuth({ id: '1', employerId: '1' });

// Create test data to exercise access control rules
await db.country.create({
  data: {
    name: 'Country1',
    members: {
      create: { id: '1' }
    },
    things: {
      create: { id: 'thing1' }
    }
  }
});

const things = await authDb.thing.findMany();
expect(things).toHaveLength(1);

tests/regression/test/v2-migrated/issue-2028.test.ts (1)

55-88: Solid regression coverage

Creating both delegated subtypes and asserting findUnique with the compound key for each case exercises the exact regression surface and should keep the delegate count behavior honest going forward.

tests/regression/test/v2-migrated/issue-2106.test.ts (1)

1-2: LGTM!

The imports are correct and appropriate for the test.

tests/regression/test/v2-migrated/issue-2038.test.ts (2)

1-2: LGTM!

Standard test imports are appropriate for this regression test.


21-24: LGTM!

The test logic correctly verifies that the @default(auth().flag) attribute applies the authenticated user's flag value to the Post's published field.

tests/regression/test/v2-migrated/issue-2247.test.ts (1)

5-57: LGTM! Schema appropriately tests delegation with relation count filters.

The schema effectively demonstrates the scenario for issue 2247:

  • Line 24: Uses @@delegate(placeType) for polymorphic delegation
  • Lines 28-42: Inheritance hierarchy (Country → Region → City)
  • Lines 50-54: Complex nested relation count filters with ?[] syntax that likely triggered the original issue

The schema structure is appropriate for verifying that delegation and relation count queries work together without errors.

packages/language/src/validators/attribute-application-validator.ts (1)

368-372: LGTM! JSON default validation is correct.

The special case handling for JSON-typed fields correctly enforces that default values must be strings, which will later be parsed as JSON. This aligns with the test case in issue-2039.test.ts and the broader changes for JSON default handling.

packages/runtime/src/client/helpers/schema-db-pusher.ts (1)

165-179: LGTM! Inheritance-aware constraint handling is correct.

The logic properly skips unique constraints for fields inherited from base models, preventing duplicate constraint definitions. Both single-field and multi-field constraints are handled correctly by checking if originModel differs from the current model.

tests/regression/test/v2-migrated/issue-2039.test.ts (1)

4-27: LGTM! Comprehensive regression test for JSON defaults.

The test effectively verifies that JSON-typed fields with string defaults are correctly parsed and persisted. The test coverage complements the validation changes in attribute-application-validator.ts and ensures the end-to-end behavior works as expected.

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

994-1022: LGTM! Count query refactoring improves consistency.

The changes standardize relation count queries to use buildModelSelect instead of direct selectFrom calls. The type casts to GetModels<Schema> are appropriate for type safety, and the refactoring ensures consistent model selection behavior across count operations.

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

825-852: LGTM! Refactoring improves code clarity.

The changes consistently use the fieldDef variable (already destructured from the loop) instead of repeatedly accessing fields[field]. This makes the code cleaner and more efficient while maintaining identical behavior. The transformation logic for generated values, updatedAt fields, and default values remains correct.
