Laravel Scout map in toSearchableArray relationship fields - laravel

Question

Is it possible to map in toSearchableArray relationship fields as well. What I mean, having User model I try to search in related model fields as well like;
/**
* Get the indexable data array for the model.
*
* #return array
*/
public function toSearchableArray()
{
return [
'name' => $this->name,
'plz' => $this->account->zip,
];
}
/**
* #return HasOne
*/
public function account(): HasOne
{
return $this->hasOne(Member::class);
}
In controller searching after results
if($request->has('s')) {
$founds = User::search($request->get('s'))->get();
}
will throw Attempt to read property "zip" on null
I do not really find any infos in documentation related to this question

Answer 1

I do have two ways to do it of which I consider one of them as crude.
Method 1:
Here's an example implementation where you're searching all of one model and then a relationship (accounts)
public function toSearchableArray()
{
$array = $this->toArray();
$array = $this->transform($array);
$array['country'] = $this->countries->map(function ($data) {
return $data['name'] ?? '';
})->toArray();
return $array;
}
Method 2:
public function toSearchableArray()
{
$array = $this->toArray();
// Customize array...
$array = [
'user_name' => $this->user_name,
'country' => $this->getCountryNameById($this->country_id),
...
];
return $array;
}
where relationship is defined in helpers or you can make a separate trait and import it in model with method.
Here relationship for country is defined within the model as
//Get Country name By id
function getCountryNameById($id) {
$country = \App\Country::select('name')->find($id);
return $country->name ?? '';
}
