Laravel 8 many to many relationshiop update/delete API (pivot table) - laravel

Question

Hello I need a help with laravel 8 many to many relationship pivot table, when I updating or deleting data in API.
These are my files info.
Firstly I created two tables:
Companies (migration file)
public function up()
{
Schema::create('companies', function (Blueprint $table) {
$table->id();
$table->string('name');
$table->string('email')->unique();
$table->timestamps();
});
}
Contacts (migration file)
public function up()
{
Schema::create('contacts', function (Blueprint $table) {
$table->id();
$table->string('name');
$table->string('email')->unique();
$table->timestamps();
});
}
After this created pivot table company_contact (migration file)
public function up()
{
Schema::create('company_contact', function (Blueprint $table) {
$table->foreignId('company_id')->constrained();
$table->foreignId('contact_id')->constrained();
});
}
Models looks like this:
Company model
class Company extends Model{
use HasFactory;
protected $fillable = [
'name',
'email'
];
public function contacts()
{
return $this->belongsToMany(Contact::class);
}
}
Contact model
class Company extends Model{
use HasFactory;
protected $fillable = [
'name',
'email'
];
public function contacts()
{
return $this->belongsToMany(Contact::class);
}
}
My routes file
Route::apiResource('companies', CompanyController::class);
My company controller
class CompanyController extends Controller{
public function index()
{
return CompanyResource::collection(Company::all());
}
public function store(CompanyStoreRequest $request)
{
$company = Company::create($request->validated());
$company->contacts()->attach($request->input('contact_id'));
return new CompanyResource($company);
}
public function show(Company $company)
{
//
}
public function update(CompanyStoreRequest $request,Company $company)
{
$contacts = Company::where('id', $company->id)->contacts()->get();
$company->contacts()->sync($request->input(['contact_id']));
$company->update($request->validated());
return new CompanyResource($company);
}
public function destroy(Company $company)
{
}
}
Company store request
public function rules()
{
return [
'name' => ['required'],
'email' => ['required', 'email'],
'contact_id' =>['required']
];
}
company resource
public function toArray($request)
{
//return parent::toArray($request);
return [
'id' => $this->id,
'name' => $this->name,
'email' => $this->email,
'contact_count' => $this->contacts()->count()
];
}
Maybe somebody can help my to write correct store() and destroy() methods in to company controller. For example when I updating company data also I want to add more contacts and to save these contacts id's in the pivot table.
With destroy method, when I delete certain company, also I want automatically delete these id’s in pivot table (relation company with contacts).
Thanks for any help.

First, you can pass the data of the contacts in an array together with the company's, using an array for several contacts and to record with the relationship use a foreach with the attach method, search on it. About the deletion you can use the softDelete, search on it too, it makes the cascade deletion of the items.
