What's new in v2

A guided tour of the v2.0 surface. For the per-version mechanical migration notes (renames, removed methods, Rector config), see the upgrading guide. This page is the why and the wow — what v2 lets you write that v1 didn't.

TL;DR

Theme	What it changed
Required parents	One call composes every NOT NULL belongsTo parent chain
recycle()	Share one parent across an entire batch
for() / has() alias overload	Explicit per-alias composition with target-type guard
Sequence context object	Per-row context ($s->index, isFirst, isLast, factory, generator) inside sequence() callables
Story scenarios	Foundry-style entity pools with getRandom() / getRandomSet()
TableAssertionsTrait	Expressive database-state assertions with sharp failure messages
Eager transaction strategy by default	Mixed direct-save + factory-save tests stay isolated again
strictDefinition detector	Catches the silent "FK in definition()" footgun before it ships
Bake quality	TimestampBehavior-managed columns are no longer baked, custom generator alias loads detected

withRequiredParents()

The single biggest ergonomic win of v2. Composes every belongsTo parent the root table requires — every NOT NULL FK — recursively, in one call:

// Tables: Authors belongsTo Address (NOT NULL); Address belongsTo City (NOT NULL);
//         City belongsTo Country (NOT NULL).
// One call satisfies the whole chain.
$author = AuthorFactory::new()->withRequiredParents()->save();

// Composes with recycle() for shared-parent batches:
$country = CountryFactory::new()->save();
$authors = AuthorFactory::new()
    ->count(50)
    ->withRequiredParents()
    ->recycle($country) // all 50 authors share this one Country
    ->saveMany();

The detector reads the schema; it only auto-composes the cases it can resolve unambiguously (single scalar NOT NULL FK). Composite-key, foreignKey => false, and nullable FKs aren't auto-resolved by design.

Three protected hooks let factory classes shape their required-parent set:

• requiredParentAssociations() — opt in extras (typically a nullable single-scalar FK the factory wants composed regardless).
• excludedRequiredParentAssociations() — opt out specific aliases at the class level. Wins over both auto-detection and the additive hook.
• allowedForeignKeysInDefinition() — exempts specific FK columns from the strictDefinition deprecation (rare, transitional).

Per-call $except and $maxDepth arguments cover the one-off cases:

$author = AuthorFactory::new()
    ->withRequiredParents(except: ['Address'], maxDepth: 2)
    ->with('Address', $myAddress)
    ->save();

See the Required parents guide for the full contract, including the pinned-FK semantics, cycle detection, and the strict mode for catching a depth cap that leaves a NOT NULL FK unsatisfied.

recycle()

Reuse a saved entity wherever any belongsTo in the build graph targets the same table — substitutes at every depth:

$country = CountryFactory::new()->save();
AddressFactory::new()
    ->count(3)
    ->with('City', CityFactory::new()->forCountries())
    ->recycle($country) // every nested City reuses this Country
    ->saveMany();

Variadic and chainable; substitutes through hasMany / belongsToMany edges into sibling belongsTo branches; refuses ambiguous same-source duplicates in a single call. See the recycle section of the associations guide.

for() / has() alias overload

Cleaner composition when a table has multiple associations targeting the same model, with a target-type guard that catches misuse at compose time:

// Disambiguates: Addresses belongsTo City AND ShippingCity
$order = OrderFactory::new()
    ->for(CityFactory::new(), 'ShippingCity')   // explicit alias
    ->has(LineItemFactory::new()->count(3))     // alias auto-resolved
    ->save();

// has() now also takes pivot data for belongsToMany joins:
$author = AuthorFactory::new()
    ->has(ArticleFactory::new()->count(2), 'Articles', ['featured' => true])
    ->save();

has() rejects pivot data on non-BTM aliases (was silently dropped in v1). The alias overload's target-type guard catches misuse like OrderFactory::for(BarFactory::new(), 'ShippingCity') — that would have silently mis-wired a Bar entity into the City slot in v1.

Sequence context object

sequence() callables now receive a single Sequence value object instead of two positional args. Exposes the current row's full context:

ArticleFactory::new()
    ->count(5)
    ->sequence(fn (Sequence $s) => [
        'rank' => $s->index,            // 0-based
        'position' => $s->position,     // 1-based
        'total' => $s->total,
        'is_first' => $s->isFirst,
        'is_last' => $s->isLast,
        'slug' => $s->generator->slug(),
        'parent' => $s->factory->getTable()->getAlias(),
    ])
    ->saveMany();

The Sequence object is constructed by the data compiler and self-validates; callables never need to instantiate it. The new sequenceField() helper covers the per-field-cycle case without writing a callable:

ProductFactory::new()
    ->count(6)
    ->sequenceField('status', 'draft', 'review', 'published')
    ->saveMany();

See the Sequence section of the factories guide.

Story scenarios

A Foundry-style abstract that adds named entity pools on top of the existing FixtureScenarioInterface. Seed data once, store named handles, sample from them in the test body — no rebuilding, no explicit threading:

class BlogStory extends Story
{
    protected function build(): void
    {
        $this->addToPool('authors', UserFactory::new()->count(10)->saveMany());
        $this->addToPool('categories', CategoryFactory::new()->count(3)->saveMany());

        ArticleFactory::new()->count(50)->saveMany();
    }
}

// In the test:
$story = $this->loadFixtureScenario(BlogStory::class);
$author = $story->getRandom('authors');
$twoCategories = $story->getRandomSet('categories', 2);

Backwards-compatible: existing scenarios that implement FixtureScenarioInterface directly keep working unchanged. See the Scenarios guide.

TableAssertionsTrait

Expressive database-state assertions composed over Factory::query(). The trait is opt-in (use TableAssertionsTrait;) — no static read surface is added to BaseFactory.

public function testCreate(): void
{
    $this->post('/articles', ['title' => 'Hello']);

    $this->assertTableHas(ArticleFactory::class, ['title' => 'Hello']);
    $this->assertTableCount(ArticleFactory::class, 1);
    $this->assertTableMissing(ArticleFactory::class, ['status' => 'spam']);
    $this->assertEntityExists($article);
    $this->assertEntityMissing($deletedArticle); // refuses never-persisted entities
}

Sharp failure messages spell out what was expected and what was found, including the actual value of relevant columns. See the Queries guide.

Eager transaction strategy restored

FactoryTransactionStrategy is eager by default again. setupTest() opens a transaction on the primary test connection up-front so that direct $table->save($entity) / raw inserts inside a test are also rolled back at teardown — not just operations that go through a Factory's save().

v1.3 had flipped this to lazy, which silently broke tests that mixed Factory build with direct $table->save() (the testFind / testValidationDefault pattern) — the direct save ran outside any transaction and leaked across methods. v2 restores the eager default while keeping additional connections lazy.

If your suite is entirely Factory-based and you want the lazy contract back, opt in via LazyFactoryTransactionStrategy (whole suite) or LazyTransactionTrait (per test class).

strictDefinition FK-in-definition() detector

Catches the silent footgun where a factory's definition() returns a belongsTo FK column directly (e.g. 'author_id' => $generator->randomDigit()). That pattern silently overrides whatever parent a caller later composes via ->with('Author', ...) — the dangling-id bug that's hard to debug because the test reads green.

Enabled by default in v2; the detector emits a deprecation that names the column, the association, and the migration path:

ArticleFactory::definition() returns "author_id", which is the foreign-key
column for the "Author" belongsTo association. Move association composition
out of definition() — use ->with('Author') in configure(), a forAuthor() /
withAuthor() helper, or pass the association at the call site.

Opt out transitionally: Configure::write('FixtureFactories.strictDefinition', false); — removed in the next major.

See the FK-in-definition guide for the migration playbook.

Bake quality

• TimestampBehavior-managed columns are no longer baked. Without this, a factory baked for a 'created'/'modified' table emitted $generator->datetime() for both, then TimestampBehavior deferred to the already-set values and the fixture row shipped with random timestamps instead of the test-run's now. Detection is by class (so aliased 'className' => 'Timestamp' loads are caught too) and only Model.beforeSave writers with new or always qualify.
• The default-data guesser was extracted into a dedicated DefaultDataGuesser class that subclasses / projects can override or extend.

See Bake reference.

Notable bug fixes worth knowing

• recycle() now substitutes mid-chain required parents (the withRequiredParents() interaction).
• foreignKey => false belongsTo composition works at persist time (was crashing with "Cannot set an empty field" in v1).
• FactoryTransactionStrategy rollback cascade and cross-connection finalize are no longer susceptible to per-connection failures.
• The pinned-FK contract is now uniform across all four entry-paths: array-instantiation, entity-instantiation, the additive requiredParentAssociations() hook, and configure()-time. Sequence overriding an instantiation pin is correctly detected.

Removed in v2

For the mechanical surface — old method names, deprecated wrappers, removed helpers — see upgrading. The bundled Rector config covers the safe renames automatically.
