Its not good solution to temporarily modify entity objects only for change API response format.
Better solution is using DTO/Transformer classes. Good example of transformers implementation is https://fractal.thephpleague.com/transformers/
In this way you can split presentation and model.
Using any packages is optional, you can write simple transformer classes like this:
// app/Transformers/ArticleTransformer.php
final class ArticleTransformer
{
public static function transform(Article $article): array
{
return [
'id' => encrypt($article->id),
// any fields
];
/*
// or if you need change only one property
return array_replace(
$article->toArray(), // or $article->jsonSerialize()
[
'id' => encrypt($article->id),
],
);
*/
}
public static function transformCollection(Collection $articles): Collection
{
return $collection->map(fn (Article $article): array => self::transform($article));
}
}
Then use this transformer:
return [
'latest_data' => ArticleTransformer::transformCollection($latestArticles),
];
Not very good, but should work:
Override jsonSerialize/toArray method of model, in returning modify your id.
