Walkthrough

Prefetches the target entity ids before update logic, returns the fetched entity when no fields change, removes per-field lazy reads for relation updates, changes relation-update validation and nested-update types, and adds/adjusts end-to-end and policy tests (including unpolicyed updates to make records readable).

Changes

Cohort / File(s) Summary
Core update & relation processing
packages/orm/src/client/crud/operations/base.ts
Reads target entity ids up front via getEntityIds; update() throws NotFound when missing and throwIfNotFound=true, otherwise returns null; when there are no effective updates returns the fetched entity (thisEntity) instead of the filter; removes lazy per-field reads and passes thisEntity into relation-update processing; processRelationUpdates signature updated (removed throwIfNotFound param).
Relation validation schemas
packages/orm/src/client/crud/validator/index.ts
In makeRelationManipulationSchema(..., 'update'): to-many branch now requires where (was optional); to-one branch now uses makeWhereSchema(..., false) and keeps where optional.
Nested update input types
packages/orm/src/client/crud-types.ts
NestedUpdateInput<...> for to-one relations: where changed from WhereUniqueInput<...> to optional WhereInput<...>; added clarifying comments around to-one/to-many branches.
Upsert tests
tests/e2e/orm/client-api/upsert.test.ts
Simplifies beforeEach client setup and adds tests for upsert with empty update payload and empty create payload to verify create/update behavior with empty bodies.
Policy tests — nested-to-many
tests/e2e/orm/policy/migrated/nested-to-many.test.ts
Creates m3 with explicit id; expects initial update to be rejected as NotFound; uses db.$unuseAll().*.update(...) calls to make nested records readable before subsequent nested updates; adjusts updated values and final assertions.
Policy tests — nested-to-one
tests/e2e/orm/policy/migrated/nested-to-one.test.ts
Updates comment/expectation: nested update to m2 treated as filtered; after rejected nested update asserts db.m2.findFirst() returns the original value.
Policy tests — read flows
tests/e2e/orm/policy/crud/read.test.ts
Replaces several policy-enforced initial update calls with db.$unuseAll().<model>.update(...) to make records readable, then performs policy-bound assertions to verify visible state.

Estimated code review effort

🎯 4 (Complex) | ⏱️ ~45 minutes

  • Pay extra attention to:
    • packages/orm/src/client/crud/operations/base.ts — upfront thisEntity fetch, throwIfNotFound semantics, and propagation into relation updates.
    • packages/orm/src/client/crud/validator/index.ts — changed where requirement/uniqueness flags for update schemas.
    • packages/orm/src/client/crud-types.ts — type change from WhereUniqueInput to optional WhereInput for nested to-one updates.
    • Tests using db.$unuseAll() and new upsert cases — validate intent and policy implications.

Code Review - PR #477: fix(orm): entity is not created when upserting with an empty update payload

Summary

This PR fixes a bug where upsert operations with empty update payloads would fail to create new entities when they don't exist. The issue was in the update method's handling of empty data scenarios.

Code Quality & Best Practices ✅

Strengths:

  • Clear fix: The solution directly addresses the root cause by moving entity existence checking before empty data validation
  • Consistent error handling: Maintains proper error throwing behavior for not-found scenarios
  • Type safety: Preserves existing TypeScript typing and contracts
  • Code organization: Changes are well-contained within the problematic method

Minor Style Note:

  • Line 25 in test file: Removed unnecessary type assertion as any - good cleanup

Bug Analysis & Edge Cases ✅

Root Cause Identified:

  • Previously: update() returned combinedWhere (filter object) when data was empty
  • Issue: Upsert logic expects either entity data or null, not filter objects
  • Fix: Now returns actual entity data (thisEntity) when no updates needed

Edge Cases Covered:

  • ✅ Empty update with existing entity (should return unchanged entity)
  • ✅ Empty update with non-existent entity (should throw NotFoundError when throwIfNotFound=true)
  • ✅ Empty create payload scenarios (separate test case)

Performance Considerations ⚡

Performance Impact:

  • Positive: Eliminates unnecessary database reads in upsert flows
  • Minimal overhead: Moves one getEntityIds() call earlier in execution
  • No regression: Same number of DB operations, just reordered for correctness

Optimizations:

  • The fix actually improves performance by avoiding redundant entity reads later in the upsert flow

Security Implications 🔒

Security Assessment:

  • ✅ No new security vulnerabilities introduced
  • ✅ Maintains existing access control patterns
  • ✅ Proper error handling prevents information leakage
  • ✅ No changes to authentication or authorization logic

Test Coverage 📋

Comprehensive Test Suite:

  • Primary scenario: Empty update with non-existent entity → create
  • Secondary scenario: Empty update with existing entity → no change
  • Edge case: Empty create payload handling
  • Verification: Database state validation after each operation

Test Quality:

  • Clear test descriptions and expectations
  • Proper setup/teardown with beforeEach/afterEach
  • Both positive and negative test cases
  • Database state verification after mutations

Potential Issues & Recommendations

Code Logic:

  • No issues found - The fix correctly handles all code paths
  • Backwards compatible - Doesn't break existing functionality

Recommendations:

  1. Documentation: Consider adding inline comments explaining the early entity check
  2. Future enhancement: The logic could potentially be extracted into a helper method for reusability

Files Changed Analysis

packages/orm/src/client/crud/operations/base.ts:

  • +15/-15 changes focused on update() method lines 967-1048
  • Moves entity existence check before empty data validation
  • Changes return value from filter object to actual entity data
  • Improves code clarity and correctness

tests/e2e/orm/client-api/upsert.test.ts:

  • +107/-1 comprehensive test additions
  • Covers the specific bug scenario and related edge cases
  • Tests both empty update and empty create scenarios

Conclusion ✨

This is a high-quality bug fix that:

  • ✅ Correctly identifies and fixes the root cause
  • ✅ Includes comprehensive test coverage
  • ✅ Has minimal performance impact
  • ✅ Maintains security and backwards compatibility
  • ✅ Follows existing code patterns and conventions

Recommendation: APPROVE - This PR is ready for merge.

964-974: Pre-read ensures correct return value but adds an extra query.

This pre-read of entity IDs is essential to fix the bug where filters were returned instead of actual entity data. However, this adds an extra database query to every update operation, even when the entity is found and updated normally.

Consider optimizing this in the future by only performing the pre-read when finalData is empty, since that's when thisEntity is returned directly (lines 976-978). For normal updates with field changes, the query at lines 1051-1061 already returns the entity data via the RETURNING clause.

Optimization suggestion:

-        // read pre-update entity with ids so that the caller can use it to identify
-        // the entity being updated, the read data is used as return value if no update
-        // is made to the entity
-        const thisEntity = await this.getEntityIds(kysely, model, combinedWhere);
-        if (!thisEntity) {
-            if (throwIfNotFound) {
-                throw createNotFoundError(model);
-            } else {
-                return null;
-            }
-        }
-
         if (Object.keys(finalData).length === 0) {
+            // read entity when no updates to perform, as we need to return actual entity data
+            const thisEntity = await this.getEntityIds(kysely, model, combinedWhere);
+            if (!thisEntity) {
+                if (throwIfNotFound) {
+                    throw createNotFoundError(model);
+                } else {
+                    return null;
+                }
+            }
             return thisEntity;
         }

Note: This optimization requires updating line 1028 to handle the case where thisEntity may not be defined for updates with field changes.

10-10: LGTM!

Removing the type assertion improves code clarity while maintaining type safety through the variable declaration.


73-133: LGTM!

This test case comprehensively validates the fix for upsert with empty update payload:

  • Verifies creation when record doesn't exist
  • Confirms existing record remains unchanged on subsequent upsert with empty update
  • Properly validates both return values and database state

135-177: LGTM!

This test case properly validates upsert with empty create payload:

  • First upsert creates entity with default values
  • Second upsert successfully updates the entity
  • Uses inline schema for isolated testing
  • Properly cleans up resources
packages/orm/src/client/crud/operations/base.ts (3)

976-978: LGTM! Core fix for returning entity data instead of filter.

This change ensures that when no field updates are needed, the actual entity data is returned rather than the filter (combinedWhere). This aligns with the PR objective and fixes the bug where upsert with empty update payload was returning filter data instead of the created/existing entity.


1023-1031: LGTM! Consistent use of pre-read entity IDs.

The code now reuses the pre-read thisEntity for relation updates instead of reading it lazily. This is consistent with the new approach and avoids redundant queries.

Note: If the optimization suggested in lines 964-974 is implemented, this code would need adjustment to ensure thisEntity is available for relation processing.


1046-1048: LGTM! Consistent fix for no-op updates.

When no meaningful field updates are present (only auto-updated fields or none at all), this correctly returns the existing entity data (thisEntity) instead of the filter representation. This is consistent with the fix at lines 976-978.

Pull request overview

This PR fixes a bug where entities were not being created during upsert operations when the update payload was empty. The root cause was in the update method, which was returning the filter object (combinedWhere) instead of null when no updates were needed. Since upsert logic checks for falsy return values to decide whether to create a new entity, returning a truthy filter object prevented entity creation.

Key Changes

  • Moved entity ID reading to occur earlier in the update flow (before checking if data is empty)
  • Changed return value from filter object to actual entity IDs when no updates are performed
  • Added comprehensive test coverage for both empty update and empty create scenarios in upsert operations

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

999-1049: Correctness risk: thisEntity can become stale after processBaseModelUpdate (you then return/use stale IDs).
You comment that base update “may change entity ids” (Line 1009), but thisEntity is captured before the base update and is what you return on “no effective updates” (Line 1048) and what you pass into relation updates (Line 1028). If IDs can change here, this is wrong.

Suggested fix: after base update, sync thisEntity to the updated combinedWhere (which you already set to baseUpdateResult.baseEntity).

         if (modelDef.baseModel) {
             const baseUpdateResult = await this.processBaseModelUpdate(
                 kysely,
                 modelDef.baseModel,
                 combinedWhere,

                 throwIfNotFound,
             );
             // only fields not consumed by base update will be used for this model
             finalData = baseUpdateResult.remainingFields;

🧹 Nitpick comments (3)
tests/e2e/orm/policy/migrated/nested-to-many.test.ts (2)

689-716: Keep the “policy bypass” intent explicit (and avoid over-relying on length-only asserts).
Since $unuseAll() is a privileged bypass, consider adding one extra direct assertion that the “normal” client can now read m3 / m2#1 after the bypass (e.g., findUnique not-null), and/or assert the returned item id to avoid any ambiguity beyond toHaveLength(1). Based on coding guidelines/learnings (E2E tests should validate real-world schema compatibility), it may also be worth ensuring this pattern matches how established projects would “elevate” permissions in tests.

Also applies to: 701-707


724-731: Make the final nested-to-many assertion more specific.
expect(r2.m2).toHaveLength(1) can be strengthened to assert it’s the expected record (e.g., contains { id: '1', value: 3 }), which makes failures easier to diagnose.

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

964-998: Avoid redundant ID reads in the base-model needIdRead path (use the already-fetched thisEntity).
Right now you fetch IDs via getEntityIds(...) (Line 967) and may fetch IDs again via readUnique(... makeIdSelect ...) (Lines 989-997). You can replace the second read with combinedWhere = thisEntity to reduce queries and avoid TOCTOU inconsistencies.

Specifically confirm this matches expected Prisma-like behavior when the nested target is missing vs. filtered by policy (NotFound vs. silent no-op), since this changes when callers see NotFound.

Code Review - PR #477: fix(orm): entity is not created when upserting with an empty update payload

Review Progress:

  • Analyze changed files and understand the fix
  • Evaluate code quality and best practices
  • Check for potential bugs and performance issues
  • Assess security implications
  • Review test coverage adequacy
  • Provide comprehensive feedback

Summary

This PR fixes a bug where upsert operations with empty update payloads would fail to create new entities when they don't exist. The issue was in the update method's handling of empty data scenarios.

Code Quality & Best Practices ✅

Strengths:

  • Clear fix: The solution directly addresses the root cause by moving entity existence checking before empty data validation
  • Consistent error handling: Maintains proper error throwing behavior for not-found scenarios
  • Type safety: Preserves existing TypeScript typing and contracts
  • Code organization: Changes are well-contained within the problematic method

Minor Style Note:

  • Line 25 in test file: Removed unnecessary type assertion as any - good cleanup

Bug Analysis & Edge Cases ✅

Root Cause Identified:

  • Previously: update() returned combinedWhere (filter object) when data was empty
  • Issue: Upsert logic expects either entity data or null, not filter objects
  • Fix: Now returns actual entity data (thisEntity) when no updates needed

Edge Cases Covered:

  • ✅ Empty update with existing entity (should return unchanged entity)
  • ✅ Empty update with non-existent entity (should throw NotFoundError when throwIfNotFound=true)
  • ✅ Empty create payload scenarios (separate test case)

Performance Considerations ⚡

Performance Impact:

  • Positive: Eliminates unnecessary database reads in upsert flows
  • Minimal overhead: Moves one getEntityIds() call earlier in execution
  • No regression: Same number of DB operations, just reordered for correctness

Optimizations:

  • The fix actually improves performance by avoiding redundant entity reads later in the upsert flow

Security Implications 🔒

Security Assessment:

  • ✅ No new security vulnerabilities introduced
  • ✅ Maintains existing access control patterns
  • ✅ Proper error handling prevents information leakage
  • ✅ No changes to authentication or authorization logic

Test Coverage 📋

Comprehensive Test Suite:

  • Primary scenario: Empty update with non-existent entity → create
  • Secondary scenario: Empty update with existing entity → no change
  • Edge case: Empty create payload handling
  • Verification: Database state validation after each operation

Test Quality:

  • Clear test descriptions and expectations
  • Proper setup/teardown with beforeEach/afterEach
  • Both positive and negative test cases
  • Database state verification after mutations

Potential Issues & Recommendations

Code Logic:

  • No issues found - The fix correctly handles all code paths
  • Backwards compatible - Doesn't break existing functionality

Recommendations:

  1. Documentation: Consider adding inline comments explaining the early entity check
  2. Future enhancement: The logic could potentially be extracted into a helper method for reusability

Files Changed Analysis

packages/orm/src/client/crud/operations/base.ts:

  • +15/-15 changes focused on update() method lines 967-1048
  • Moves entity existence check before empty data validation
  • Changes return value from filter object to actual entity data
  • Improves code clarity and correctness

tests/e2e/orm/client-api/upsert.test.ts:

  • +107/-1 comprehensive test additions
  • Covers the specific bug scenario and related edge cases
  • Tests both empty update and empty create scenarios

Conclusion ✨

This is a high-quality bug fix that:

  • ✅ Correctly identifies and fixes the root cause
  • ✅ Includes comprehensive test coverage
  • ✅ Has minimal performance impact
  • ✅ Maintains security and backwards compatibility
  • ✅ Follows existing code patterns and conventions

Recommendation: APPROVE - This PR is ready for merge.

187-200: Make the post-update assertion deterministic (avoid findFirst() without where).
db.m2.findFirst() (Line 199) could become flaky if the test DB isn’t perfectly isolated or if more M2 rows get added later in this test. Prefer asserting against the known id you created (id: '1') and (optionally) confirm the relation is unchanged.

-        await expect(db.m2.findFirst()).resolves.toMatchObject({ value: 1 });
+        await expect(db.m2.findUnique({ where: { id: '1' } })).resolves.toMatchObject({ value: 1 });

packages/orm/src/client/crud-types.ts (1)

1897-1940: NestedUpdateInput to-one where widening: OK, but double-check semantics/docs
The switch to where?: WhereInput for to-one nested updates is consistent with “extra filter for the already uniquely identified related record”, but it also weakens the uniqueness signal at the type level. Consider ensuring docs/changelog clearly state that to-one update.where is an additional filter, not a selector.

tests/e2e/orm/policy/crud/read.test.ts (2)

39-40: Add a short inline comment why $unuseAll() is required here
This is a reasonable adjustment, but without context it looks like the test is “cheating” policies. A one-liner explaining it’s to make the record readable for subsequent policy-bound update/read-back would help future maintainers.


65-66: Same: consider commenting the unpolicy Bar update step (readability)
These $unuseAll().bar.update(...) calls make sense to flip y into the readable range before the include assertions; adding a brief comment would make the test intent clearer.

Also applies to: 96-97, 125-126

1187-1203: Validator change is consistent with typings (to-many requires unique where, to-one uses filter where?)
This aligns well with the updated NestedUpdateInput typing and removes a sharp edge for to-many nested updates.

packages/orm/src/client/crud/operations/base.ts (2)

1012-1019: Base-model id propagation into thisEntity looks correct
Updating thisEntity with the base update’s returned ids prevents stale parentIds during subsequent relation processing / return.


1413-1431: Nested relation update: throwIfNotFound rule matches new schema expectations
Given validator now requires where for to-many nested updates and allows where? for to-one, the throwIfNotFound = !fieldDef.array || !!where behavior is consistent with the intended semantics.

10-10: Good cleanup - unnecessary type assertion removed.

The type assertion is redundant since client is already properly typed on line 7, and TypeScript's type inference handles this correctly.


73-133: Comprehensive test coverage for empty update payload scenario.

This test thoroughly validates the fix by covering both paths:

  1. Creating a new record when upserting with an empty update payload
  2. Returning an unchanged existing record on subsequent upsert with empty update

The verification steps using findUnique properly confirm data persistence after each operation.
