/**
|
|
* Re-runnable entity generator wrapper (ORM migration Plan 2, Task 2).
|
|
*
|
|
* `@mikro-orm/entity-generator` 7.2.1 already produces the Phase 0 shape
|
|
* (`Days`/`DayNotes`/`Trips`, see `docs/superpowers/specs/2026-09-21-orm-repository-migration-design.md`
|
|
* D1/D2) from the migrated schema once configured with a naming strategy whose
|
|
* `columnNameToProperty` is the identity — every scalar and FK twin comes out
|
|
* named exactly like its column. What it does NOT do on its own (verified by
|
|
* reading `node_modules/@mikro-orm/entity-generator/*.js` and by running this
|
|
* wrapper against the real schema, not by assumption):
|
|
*
|
|
* - it leaves multi-word relation names snake_case and inverse-collection
|
|
* names camelCase (the opposite of what Phase 0 does for each);
|
|
* - it never marks a relation `.hidden()`;
|
|
* - it emits `p.datetime()` / `p.unknown().columnType('REAL')` instead of
|
|
* `p.type(DbTimestampType)` / `p.double()`;
|
|
* - it leaves `updateRule('no action')` / `deleteRule('no action')` noise
|
|
* (SQLite reports "NO ACTION" for every FK that never named a rule);
|
|
* - integer autoincrement primary keys come out `.primary().nullable()`
|
|
* (SQLite's `PRAGMA table_info` carries no AUTOINCREMENT flag);
|
|
* - it never binds a `repository:`;
|
|
* - the "collision class" (an FK column with no `_id` suffix, e.g.
|
|
* `country`, `created_by`) gets a relation named after the column AND a
|
|
* same-named scalar twin — colliding — and even once renamed, the
|
|
* generator's own override mechanism for a to-one relation only ever
|
|
* emits `.name(<column>)`, which Task 0/1 proved is inert for a relation
|
|
* (`.joinColumn(<column>)` is the only thing that actually pins the FK
|
|
* column; see `.superpowers/sdd/2026-09-22-orm-phase2-entity-rewrite/task-0-report.md`
|
|
* and `task-1-report.md`, fact (c)).
|
|
*
|
|
* Each gap above is closed by a single named rule function, applied either at
|
|
* the metadata level (`onProcessedMetadata`, preferred — the MikroORM-
|
|
* documented hook for this exact purpose) or, only where the metadata cannot
|
|
* carry the fix into the rendered `defineEntity` call (traced against the
|
|
* actual renderer in `SourceFile.js`/`DefineEntitySourceFile.js`, not
|
|
* guessed), as a small text pass over the generated source. See
|
|
* `task-2-report.md` for which rule lives at which level and why.
|
|
*
|
|
* This script never writes into `src/db/entities/` on its own — `--write` is
|
|
* accepted (Task 3 uses it) but this task never passes it. It never opens
|
|
* `data/travel.db` either: it migrates a throwaway temp file (via the same
|
|
* `Migrator` extension `buildApp()` uses, configured directly rather than by
|
|
* importing `src/db/orm.ts` — that module transitively imports
|
|
* `src/db/database.ts`, which opens `resolveDbPath()` — i.e. the real
|
|
* database file — as a side effect of being imported at all).
|
|
*
|
|
* Usage:
|
|
* node --import tsx scripts/generate-entities.ts --out <dir>
|
|
* node --import tsx scripts/generate-entities.ts --write # Task 3 only

export const KNOWN_DIFFS = `
|
|
1. Index duplicated onto the FK twin. The generator carries a relation's named
|
|
index (".index('idx_days_trip_id')") onto BOTH the owning relation AND its
|
|
persist(false) scalar twin; the hand-written files only ever declare it on
|
|
the relation. Harmless (SQLite would just create the same index once) —
|
|
verified against the actual generated output, not assumed.
|
|
2. Class-field TS annotation on an integer autoincrement primary key. The
|
|
hand-written files declare it "id?: number | null;" as an ergonomic hint
|
|
(you can build the entity before an id is assigned); the generator's own
|
|
renderer ties both the "?" and the "| null" suffix to metadata property
|
|
"nullable" (see SourceFile.js#getPropertyDefinition), and rule 3 below sets
|
|
nullable=false on this exact property so the metadata BUILDER CHAIN has no
|
|
stray ".nullable()" (matching the reference's *metadata*, which is what the
|
|
parity tests and the ORM itself read) — at the cost of the class field
|
|
rendering "id!: number & Opt;" instead (and the resulting "type Opt" import).
|
|
Purely a TypeScript-side annotation; it does not change runtime behaviour,
|
|
hydration, or the metadata the schema parity test compares. Confirmed by
|
|
generating the real schema, not assumed. It is also safe at the database
|
|
level despite the metadata's builder chain having no explicit
|
|
".autoincrement()" call for this property: MikroORM's own
|
|
MetadataDiscovery#initAutoincrement (node_modules/@mikro-orm/core/metadata/MetadataDiscovery.js)
|
|
defaults "autoincrement ??= true" for any single numeric PK at discovery
|
|
time, so the ORM treats the generated and hand-written metadata
|
|
identically once loaded — confirmed by generating the real schema and
|
|
inserting through the written entity (Days.repository.test.ts's insert
|
|
passes). Task 3 should have its own parity test (a PARITY-010 or sibling)
|
|
asserting "autoincrement === true" in the *discovered* metadata for every
|
|
integer PK, so this inference is pinned rather than assumed going
|
|
forward.
|
|
3. Method-call order within a builder chain (e.g. ".deleteRule('cascade').hidden().index(...)"
|
|
vs the hand-written files' ".hidden().deleteRule('cascade').index(...)").
|
|
The renderer assembles each property's options in its OWN fixed sequence
|
|
(kind-specific options — fieldName/deleteRule/updateRule/primary/generated —
|
|
then common flags — nullable/hidden/etc. — then index/unique), which the
|
|
hand-written files, authored before this generator produced this shape, did
|
|
not follow. Cosmetic only: every option present is the same, only the
|
|
textual order of independent chained calls differs.
|
|
4. "defaultRaw" renders as a backtick template literal ("\`CURRENT_TIMESTAMP\`")
|
|
rather than a single-quoted string ("'CURRENT_TIMESTAMP'"). SourceFile.js's
|
|
own renderer always uses a template literal for defaultRaw specifically (so
|
|
raw SQL containing "\${" is escaped rather than interpolated) — the
|
|
hand-written files predate this generator and used a plain string.
|
|
Semantically identical TypeScript.
|
|
5. A nullable column's DB-level default. Phase 0's own hand-written files are
|
|
not internally consistent about restating a NULLABLE column's default in
|
|
metadata at all: "DayNotes.sort_order" (nullable, "REAL DEFAULT 0") has
|
|
".default(0)"; "DayNotes.icon" (nullable, "TEXT DEFAULT '📝'") has none
|
|
at all, relying only on the class-field initialiser. The wrapper's default
|
|
rule (RULE_normalizeLiteralDefaults) deliberately scopes itself to NOT
|
|
NULL columns only — see that rule's doc comment — and leaves whatever the
|
|
generator's own (occasionally "defaultRaw" instead of "default", or
|
|
entirely absent) rendering produces for a nullable column. This is exactly
|
|
Task 0's skipped PARITY-005 (column defaults) territory, not this task's.
|
|
6. Trailing blank line / whitespace at end of file, if any — a generator
|
|
formatting convention, immaterial to the parsed module.
|
|
|
|
Fix round 1 (task-2-fix-brief.md) resolved the former #6 (the
|
|
VacayUserSettings.user_id PK-twin nullability judgment call) by taking the
|
|
generator's answer as correct and updating the hand-written file to match
|
|
(see .superpowers/sdd/2026-09-22-orm-phase2-entity-rewrite/task-2-review.md,
|
|
"#6 — generator or hand-written file?") — it is no longer a diff at all, so
|
|
it is no longer listed here.
