better-data: Adding a DataObject

For library maintainers and downstream contributors who add or modify a DataObject subclass inside better-data. Every typed shape — production DTOs in src/, test fixtures in tests/Fixtures/, plugin-level DTOs in the companion testbed — extends the abstract DataObject (src/DataObject.php:36) and is the foundation that every engine (sources, sinks, validation, Presenter, REST schema, better-route bridge) reads against.

Misconception this skill corrects

"I'll just declare the constructor parameters with the types I want and set the values when I instantiate the class — defaults are optional."

In better-data, defaults are load-bearing. The hydration entry point DataObject::fromArray (src/DataObject.php:47-79) iterates ReflectionParameters and treats any parameter without isDefaultValueAvailable() (and without allowsNull()) as REQUIRED — throwing MissingRequiredFieldException. PHP's Reflection silently demotes earlier-positioned defaults to "required" if a later parameter has no default — so a single missing default at the end cascades and breaks ::fromArray for the whole DTO.

Other AI-prone misconceptions:

  • "I'll add encrypt: true to the MetaKey and store the property as a plain string." Wrong shape — #[Encrypted] writes ciphertext but the in-memory value is still a plain string that leaks via var_dump / print_r / serialize. Use Secret as the property type.
  • "I'll add a public mutator method (setEmail()) to make consumer code more ergonomic." Wrong — every DTO is final readonly class. Mutation is $dto->with(['email' => 'new@example.com']) which returns a NEW instance. Mutators break the immutability contract that Secret, route-side projection, and Presenter caching all depend on.

When to use this skill

Trigger when ANY of the following is true:

  • Adding a new final readonly class extends DataObject under src/, tests/Fixtures/, or the companion plugin's Dto/.
  • Adding, removing, or retyping a constructor parameter on an existing DTO.
  • The diff or PR title mentions: "new DTO", "add Dto", "add field to Dto", "introduce Dto".
  • Reviewing a class that extends DataObject — use this skill's checklist before approving.
  • Hitting MissingRequiredFieldException at runtime — usually the cause is a trailing parameter without a default.

Workflow

1. Choose the file location
What you're buildingPath
Production DTO (library users hydrate it)src/<area>/<Name>Dto.php
Test-only fixturetests/Fixtures/<Name>Dto.php
Plugin-level DTO (companion testbed)wp-content/plugins/better-data-plugin-test/src/Dto/<Name>Dto.php
2. Declare the class
namespace MyNamespace;

use BetterData\DataObject;
use BetterData\Source\HasWpSources;
use BetterData\Sink\HasWpSinks;
use BetterData\Presenter\HasPresenter;

final readonly class ProductDto extends DataObject
{
    use HasWpSources;
    use HasWpSinks;
    use HasPresenter;

    public function __construct(
        public int $id = 0,
        public string $post_title = '',
        public string $post_status = 'publish',
    ) {}
}

Three non-negotiables:

  • final — never extended. The library does not support subclass-of-DTO patterns.
  • readonly — every property is immutable. Hydration writes once via newInstanceArgs; consumers mutate via ->with(...).
  • extends DataObject — gives you ::fromArray, ::fromArrayValidated, ->toArray(), ->with(), attribute-aware coercion.
3. Constructor-promoted parameters with defaults on every trailing one

The single most important rule. Every parameter must have either an explicit default OR be nullable. Recommended defaults by type:

TypeDefault
int= 0
string= ''
float= 0.0
bool= false
array= []
?DateTimeImmutable= null
?Secret= null (NEVER new Secret(''))
BackedEnumfirst case (= MyEnum::Default) or = null if nullable

PHP-side reasoning: ReflectionParameter::isDefaultValueAvailable() returns false when ANY required parameter sits later in the signature. The hydrator at src/DataObject.php:63-73 checks this exact predicate; missing a default at position N silently breaks defaults at positions 0..N-1.

4. Choose the most-specific type possible

Better-data leans on type information for coercion, schema generation, and Presenter formatting. Be specific:

  • ?DateTimeImmutable over ?string for timestamps — TypeCoercer parses ISO-8601 strings and WC_DateTime instances automatically.
  • Secret over string for credentials — provides redacted __toString, throwing __serialize, leak-probe-tested behaviour.
  • BackedEnum subclass over string for closed sets — TypeCoercer::toEnum resolves the value or throws TypeCoercionException.
  • A specific DataObject subclass over array for nested structures — coercion delegates to $class::fromArray() recursively (src/DataObject.php:195-197).
5. Decorate with attributes

Each attribute is a pure data carrier (src/Attribute/) read by one or more engines:

AttributeRead byPurpose
#[MetaKey('key', type: 'number', showInRest: true)]OptionSink, PostSink::toMeta, RestSchemaBuilderMap property to a meta_key and REST schema
#[PostField('post_date_gmt')]PostSink, PostSourceRename DTO param to a wp_posts column
#[UserField], #[TermField], #[Column]corresponding sink/sourceSame but for users / terms / custom rows
#[Sensitive]Presenter::sensitiveFieldNamesRedact in present()->toArray()
#[Encrypted]EncryptionEngine, SinkProjection, AttributeDrivenHydratorAt-rest encryption — pair with Secret type
#[ListOf(Element::class)]DataObject::coerceParameterCoerce each array element into Element
#[Rule\Required], #[Rule\Email], #[Rule\Min(0)], …BuiltInValidatorValidation in ::fromArrayValidated
#[DateFormat('Y-m-d')]Presenter, sink projectionNon-default DateTime serialization
6. Add the relevant traits

The traits are syntactic sugar over PostSource, PostSink, etc. — they make Dto::fromPost($id) and $dto->saveAsPost() work without manual instantiation:

use HasWpSources;  // ::fromPost($id), ::fromUser($id), ::fromTerm($id), ::fromOption($name), ::fromRow($row)
use HasWpSinks;    // ->saveAsPost(), ->saveAsUser(), ->saveAsTerm(), ->saveAsOption(), ->saveAsRow()
use HasPresenter;  // ->present() returns a Presenter builder

Don't add a trait you won't use. Including HasWpSinks on a read-only fixture pollutes the API surface.

7. Realistic example
namespace MyPlugin\Dto;

use BetterData\DataObject;
use BetterData\Secret;
use BetterData\Source\HasWpSources;
use BetterData\Sink\HasWpSinks;
use BetterData\Presenter\HasPresenter;
use BetterData\Attribute\MetaKey;
use BetterData\Attribute\PostField;
use BetterData\Attribute\Encrypted;
use BetterData\Attribute\Sensitive;
use BetterData\Validation\Rule;

final readonly class ProductDto extends DataObject
{
    use HasWpSources;
    use HasWpSinks;
    use HasPresenter;

    public function __construct(
        public int $id = 0,
        #[Rule\Required] public string $post_title = '',
        public string $post_status = 'publish',
        public string $post_type = 'product',
        #[PostField('post_date_gmt')] public ?\DateTimeImmutable $publishedAt = null,
        #[MetaKey('_price'), Rule\Min(0)] public float $price = 0.0,
        #[MetaKey('_sku'), Rule\Regex('/^[A-Z]{2,4}-\d+$/')] public string $sku = '',
        #[MetaKey('_api_key'), Encrypted] public ?Secret $apiKey = null,
        #[MetaKey('_notes'), Sensitive] public ?string $notes = null,
    ) {}
}

Verify the DTO works end-to-end:

Critical rules

  • final readonly class extends DataObject. Never skip final, never skip readonly, never skip extends DataObject. Tools and engines all assume this shape.
  • Every constructor parameter has a default OR is nullable. Trailing-without-default cascades and breaks earlier defaults via PHP's Reflection. int $id = 0, string $foo = '', ?T $bar = null.
  • ?Secret = null, never new Secret(''). An empty-string Secret is worse than no Secret because consumers can't distinguish "intentionally absent" from "set to empty string".
  • #[Encrypted] requires Secret type. The library tolerates plain-string + #[Encrypted] for backward compatibility but the in-memory value leaks. Always pair them.
  • Mutate via ->with([...]), never via setter. with() calls static::fromArray(array_replace($snapshot, $changes)) (src/DataObject.php:119-130), preserving immutability and re-running coercion.
  • One trait per concern. HasWpSources for read, HasWpSinks for write, HasPresenter for output. Add only what you use.
  • Specific types over loose ones. ?DateTimeImmutable over ?string, BackedEnum over string, nested DataObject over array.
  • Constructor parameter names == hydration keys. fromArray(['post_title' => 'X']) sets $post_title. Renaming a param is a breaking change for every caller.

Common mistakes

// WRONG — trailing param without default cascades
public function __construct(
    public int $id = 0,
    public string $name = '',
    public ?\DateTimeImmutable $createdAt,  // no default → ALL params reported "required"
) {}
// Result: ProductDto::fromArray(['id' => 5]) throws MissingRequiredFieldException for "id"
// even though it has = 0 — because Reflection demoted it.

// RIGHT
public function __construct(
    public int $id = 0,
    public string $name = '',
    public ?\DateTimeImmutable $createdAt = null,
) {}

// WRONG — empty-string Secret as default
#[MetaKey('_api_key'), Encrypted] public Secret $apiKey = new Secret('')
// Looks tidy but: caller can't tell "user never set a key" from "user typed nothing".
// Worse, default expressions in promoted constructor parameters MUST be constants — this
// won't even parse. Use ?Secret = null.

// RIGHT
#[MetaKey('_api_key'), Encrypted] public ?Secret $apiKey = null,

// WRONG — #[Encrypted] on a plain string
#[MetaKey('_api_key'), Encrypted] public string $apiKey = ''
// Ciphertext goes to DB on save, decrypts back on hydration — but in-memory the value is a
// plain string.

# better-data: Adding a DataObject

For library maintainers and downstream contributors who add or modify a `DataObject` subclass inside [better-data](../../README.md). Every typed shape — production DTOs in `src/`, test fixtures in `tests/Fixtures/`, plugin-level DTOs in the companion testbed — extends the abstract `DataObject` ([src/DataObject.php:36](DataObject.php)) and is the foundation that every engine (sources, sinks, validation, Presenter, REST schema, better-route bridge) reads against.

## Misconception this skill corrects

> "I'll just declare the constructor parameters with the types I want and set the values when I instantiate the class — defaults are optional."

In better-data, defaults are **load-bearing**. The hydration entry point `DataObject::fromArray` ([src/DataObject.php:47-79](DataObject.php)) iterates `ReflectionParameter`s and treats any parameter without `isDefaultValueAvailable()` (and without `allowsNull()`) as REQUIRED — throwing `MissingRequiredFieldException`. PHP's Reflection silently demotes earlier-positioned defaults to "required" if a later parameter has no default — so a single missing default at the end cascades and breaks `::fromArray` for the whole DTO.

Other AI-prone misconceptions:

- "I'll add `encrypt: true` to the `MetaKey` and store the property as a plain `string`." Wrong shape — `#[Encrypted]` writes ciphertext but the in-memory value is still a plain string that leaks via `var_dump` / `print_r` / `serialize`. Use `Secret` as the property type.
- "I'll add a public mutator method (`setEmail()`) to make consumer code more ergonomic." Wrong — every DTO is `final readonly class`. Mutation is `$dto->with(['email' => 'new@example.com'])` which returns a NEW instance. Mutators break the immutability contract that `Secret`, route-side projection, and Presenter caching all depend on.

## When to use this skill

Trigger when ANY of the following is true:

- Adding a new `final readonly class extends DataObject` under `src/`, `tests/Fixtures/`, or the companion plugin's `Dto/`.
- Adding, removing, or retyping a constructor parameter on an existing DTO.
- The diff or PR title mentions: "new DTO", "add Dto", "add field to <X>Dto", "introduce <Foo>Dto".
- Reviewing a class that extends `DataObject` — use this skill's checklist before approving.
- Hitting `MissingRequiredFieldException` at runtime — usually the cause is a trailing parameter without a default.

## Workflow

### 1. Choose the file location

| What you're building | Path |
|---|---|
| Production DTO (library users hydrate it) | `src/<area>/<Name>Dto.php` |
| Test-only fixture | `tests/Fixtures/<Name>Dto.php` |
| Plugin-level DTO (companion testbed) | `wp-content/plugins/better-data-plugin-test/src/Dto/<Name>Dto.php` |

### 2. Declare the class

```php
namespace MyNamespace;

use BetterData\DataObject;
use BetterData\Source\HasWpSources;
use BetterData\Sink\HasWpSinks;
use BetterData\Presenter\HasPresenter;

final readonly class ProductDto extends DataObject
{
    use HasWpSources;
    use HasWpSinks;
    use HasPresenter;

    public function __construct(
        public int $id = 0,
        public string $post_title = '',
        public string $post_status = 'publish',
    ) {}
}
```

Three non-negotiables:

- `final` — never extended. The library does not support subclass-of-DTO patterns.
- `readonly` — every property is immutable. Hydration writes once via `newInstanceArgs`; consumers mutate via `->with(...)`.
- `extends DataObject` — gives you `::fromArray`, `::fromArrayValidated`, `->toArray()`, `->with()`, attribute-aware coercion.

### 3. Constructor-promoted parameters with defaults on every trailing one

The single most important rule. Every parameter must have either an explicit default OR be nullable. Recommended defaults by type:

| Type | Default |
|---|---|
| `int` | `= 0` |
| `string` | `= ''` |
| `float` | `= 0.0` |
| `bool` | `= false` |
| `array` | `= []` |
| `?DateTimeImmutable` | `= null` |
| `?Secret` | `= null` (NEVER `new Secret('')`) |
| `BackedEnum` | first case (`= MyEnum::Default`) or `= null` if nullable |

PHP-side reasoning: `ReflectionParameter::isDefaultValueAvailable()` returns false when ANY required parameter sits later in the signature. The hydrator at [src/DataObject.php:63-73](DataObject.php) checks this exact predicate; missing a default at position N silently breaks defaults at positions 0..N-1.

Better-data leans on type information for coercion, schema generation, and Presenter formatting. Be specific:

- `BackedEnum` subclass over `string` for closed sets — `TypeCoercer::toEnum` resolves the value or throws `TypeCoercionException`.
- A specific `DataObject` subclass over `array` for nested structures — coercion delegates to `$class::fromArray()` recursively ([src/DataObject.php:195-197](DataObject.php)).

### 5. Decorate with attributes

Each attribute is a pure data carrier ([src/Attribute/](Attribute/)) read by one or more engines:

| Attribute | Read by | Purpose |
|---|---|---|
| `#[MetaKey('key', type: 'number', showInRest: true)]` | `OptionSink`, `PostSink::toMeta`, `RestSchemaBuilder` | Map property to a `meta_key` and REST schema |
| `#[PostField('post_date_gmt')]` | `PostSink`, `PostSource` | Rename DTO param to a `wp_posts` column |
| `#[UserField]`, `#[TermField]`, `#[Column]` | corresponding sink/source | Same but for users / terms / custom rows |
| `#[Sensitive]` | `Presenter::sensitiveFieldNames` | Redact in `present()->toArray()` |
| `#[Encrypted]` | `EncryptionEngine`, `SinkProjection`, `AttributeDrivenHydrator` | At-rest encryption — pair with `Secret` type |
| `#[ListOf(Element::class)]` | `DataObject::coerceParameter` | Coerce each array element into `Element` |
| `#[Rule\Required]`, `#[Rule\Email]`, `#[Rule\Min(0)]`, … | `BuiltInValidator` | Validation in `::fromArrayValidated` |
| `#[DateFormat('Y-m-d')]` | Presenter, sink projection | Non-default DateTime serialization |

### 6. Add the relevant traits

The traits are syntactic sugar over `PostSource`, `PostSink`, etc. — they make `Dto::fromPost($id)` and `$dto->saveAsPost()` work without manual instantiation:

```php
use HasWpSources;  // ::fromPost($id), ::fromUser($id), ::fromTerm($id), ::fromOption($name), ::fromRow($row)

```

Don't add a trait you won't use. Including `HasWpSinks` on a read-only fixture pollutes the API surface.
