Above is a response by using Eloquent: API Resources.
I would like to put category name instead of category_id.
Below is resource class
public function toArray($request)
{
return [
'nickname' => $this->nickname,
'certificates' => $this->certificates,
];
}
certificates are in array (hasMany relationship)
certificates belongsTo category

Answer 1

In this case, in the resource class you can fetch category name for each certificate and attach it.
public function toArray($request)
{
$certificateList = $this->certificates;
foreach($certificateList as $ceritificate) {
// fetch only the category name from the database.
// attach to the certificate.
$categoryName = Category::where('id', $certificate->category_id)->pluck('name')->first();
$certificate->setAttribute('category_name, $categoryName);
}
// then as usual
return [
'nick_name' => $this->nick_name,
'certificates' => $certificateList
];
}

This Might Help,
Run a foreach loop
$category = "Your SELECT Query";
foreach ($category as $value) {
$categoryId = json_decode($value->category_id);
$x = Category::select('certname')->whereIn('id', $categoryId)->get();
foreach ($x as $as) {
$y[] = $as->certname;
}
$value->certname = $y;

Answer 3

you can just do it like this
in controler
return CertificateResource::collection(Certificate::with('category')->get());
in CertificateResource
return [
'nickname' => $this->nickname,
'certificates' => $this->certificates,
'category_name'=>$this->whenLoaded('category', function () {
return $this->category->category_name;
}),
];
