fix(orm): alias delegate joins in relation subqueries so they don't shadow outer tables - #2877
Conversation
…hadow outer tables A delegate base or sub model was always joined under its own model name. In a relation subquery that join hid an outer table of the same name, so a relation pointing into its own delegate hierarchy correlated the inner row with itself. Filters (`some`, `none`, `every`, to-one `is`), `count`, `_count` and `include` returned wrong results through the base model, with no error. - join delegate bases and sub models under `delegateJoinAlias`: their model names for a top-level query (unchanged SQL), aliases derived from the subquery alias otherwise - resolve inherited fields through `delegateFieldAlias` wherever the base model name was used as the alias - soft-delete: filter an inherited marker through the same alias Fixes zenstackhq#2870 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Issue
#2870requires correct relation filters and_countqueries through a delegate base, while preserving sub-model behavior.buildDelegateJoinnow usesdelegateJoinAliasfor relation subqueries, and inherited fields usedelegateFieldAlias. Regression tests coversome,none,every, counts, filtered counts, many-to-many cases, and a sub-model control. The tests also cover related include and to-one cases affected by the same shadowing defect.

Explanation
The broader to-one, include, many-to-many, ordering, access-policy, and soft-delete changes use the same delegate-table aliasing fix. The added tests validate these affected query paths. Top-level model-name joins remain unchanged. No unrelated change is demonstrated.

- Line 1176: Update applyRelationOrderBy to join the related model’s delegate
base aliases before applying nested ordering, ensuring aliases returned by
delegateJoinAlias are present in the query. Preserve the existing relation join
and ordering behavior for models without inherited order fields.

Ordering by an inherited field of a to-one relation referenced the related model's delegate base, which was never joined. Ordering by a relation declared on a delegate base read the foreign key from the sub model's table. - join the related model's delegate bases under `delegateJoinAlias` - join the relation through `delegateFieldAlias`, as the to-one filter does Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Fixes #2870.
Problem
A delegate base or sub model is always joined under its own model name, for example
left join "Item" on .... In a relation subquery that join hides any outer table with the same name. So when a relation points into its own delegate hierarchy, the subquery's correlation compares the inner row with itself. The query returns wrong results with no error.The bug is wider than the issue describes. All of these were wrong on
dev, on SQLite and PostgreSQL:some,noneandeveryfilters, andcount, through the base model (the issue's cases)item.findMany({ where: { pinnedTask: { is: {} } } })_count, with or without awhere_countandincludeinside one hierarchyincludein both directions, for examplenote.findUnique({ include: { source: true } })returnssource: null, because the related delegate's sub model joins (left join "Note") hide the outer"Note"Queries through the sub model, where the outer table has a different name, were correct.
Fix
buildDelegateJoinnow joins a base or sub model under an alias from the newdelegateJoinAlias:"$$t1$Item". They can no longer hide an outer table.Each place that used
fieldDef.originModelas the alias of an inherited field now callsdelegateFieldAlias. These places are filters, cursor, to-one join pairs, order by, selected fields, sub model JSON fields, and inherited relation selection inBaseOperationHandler.Ordering by a to-one relation now joins the related model's delegate bases, so it can order by an inherited field. It also joins a relation declared on a delegate base through the base table, as the to-one filter does.
The soft-delete plugin referenced the base table by model name when it filtered a sub model on a marker inherited from a delegate base. It now uses
delegateJoinAliastoo. Without that change, reading a soft-delete delegate through a relation fails withno such column: Content.deletedAt.Access policy rules were already correct (#2845 aliases relation tables in the policy transformer). Policy reads that include these relations were affected through the ORM, and the regression test covers them.
Tests
tests/regression/test/issue-2870.test.ts: to-many filters, to-one filters,_count(plain, filtered, many-to-many, order by), ordering by an inherited field of a to-one relation,includein both directions and many-to-many, the sub model control case, and an access policy case. 6 of the 7 tests fail ondevand pass with the fix. The sub model control passes on both.packages/plugins/soft-delete/test/soft-delete.test.ts: a soft-deleted delegate row reached throughinclude,_countand a relation filter. It fails without the plugin change.regression274 passed,e2e1103 passed, plus every other package's tests. The only failures were the MySQL timezone tests (no MySQL server here) andnow-function.test.tson PostgreSQL. Both fail the same way on unchangeddev.🤖 Generated with Claude Code
