Eloquent Resolver

EloquentEntitySetResolver resolves OData queries against an Eloquent model class. It is the default resolver for entity sets backed by Laravel models.

Usage

use LaravelUi5\OData\Driver\Sql\EloquentEntitySetResolver;

$builder->bindEntitySet(
    $container->getEntitySet('Products'),
    new EloquentEntitySetResolver(Product::class),
);

When using discoverModel(), this resolver is auto-bound. You do not need to create it manually.

Constructor

new EloquentEntitySetResolver(string $modelClass)

Parameter	Type	Purpose
$modelClass	class-string<Model>	Fully qualified Eloquent model class

Supported query options

Option	How it maps to Eloquent
$filter	where() clauses via FilterToEloquent visitor
$search	LIKE '%term%' on all Edm.String properties, OR'd together
$select	->select([...]) on the query
$orderby	->orderBy($col, $dir) for each clause
$top	->limit($n)
$skip	->offset($n)
$count	->count() (separate query, ignores pagination)
$expand	->with([...]) eager loading
$compute	Evaluated in PHP after fetch (concat, arithmetic, date functions)

Interfaces implemented

• EntitySetResolverInterface -- resolve() yields rows, count() returns total
• EntityResolverInterface -- resolveOne() fetches a single entity by key

Both are satisfied by the same instance, so a single binding covers collection and single-entity access.

How results are yielded

• Without $expand: uses cursor() for memory-efficient streaming. Rows are yielded one at a time.
• With $expand: uses get() because cursor() does not support eager loading. All rows are loaded into memory, then yielded.

Each row is converted to an associative array via Model::toArray().

Expand behavior

Simple expand (no nested options):

GET /odata/Flights?$expand=passengers

Maps to ->with(['passengers']).

Constrained expand (nested query options):

GET /odata/Flights?$expand=passengers($select=name;$top=5;$filter=age gt 18)

Maps to ->with(['passengers' => function ($q) { ... }]) with nested filter, select, orderby, top, and skip applied to the relation query. The PK and FK columns are always included in nested selects to ensure Eloquent can match relations to parent rows.
