Relation Repository

Manage relations between records. The resource type is idsfromrelation.

Querying

use Innobrain\OnOfficeAdapter\Enums\OnOfficeRelationType;
use Innobrain\OnOfficeAdapter\Facades\RelationRepository;

// Get contact persons for estate
$contacts = RelationRepository::query()
    ->relationType(OnOfficeRelationType::ContactPersonAll)
    ->parentIds([48])
    ->get();

// Get estates for owner
$estates = RelationRepository::query()
    ->relationType(OnOfficeRelationType::Owner)
    ->childIds([1234])
    ->get();

addParentIds() and addChildIds() append to the already set ids instead of replacing them.

get() returns a Collection keyed by parent ID => array of related child IDs, not full records. The ID arrays can contain duplicates — dedupe before fetching the related records.

Processing All Results

Unlike other builders, the relation builder's each() does not chunk: it fetches all results and invokes the callback once with the full Collection.

use Illuminate\Support\Collection;

RelationRepository::query()
    ->relationType(OnOfficeRelationType::ContactPersonAll)
    ->parentIds([48])
    ->each(function (Collection $relations) {
        // All relations at once
    });

Creating

RelationRepository::query()
    ->relationType(OnOfficeRelationType::Buyer)
    ->parentIds([48])
    ->childIds([181])
    ->create();

WARNING

Don't swap parentIds and childIds — the relation type determines which is which, and the wrong direction is not an error: the API returns empty lists with a success status, indistinguishable from "no links". For CalendarEstate, CalendarAddress, TaskEstate, and TaskAddress, the estate or address is the child.
