Eloquent's fillable not working with mutators - laravel

Question

I have a following model:
<?php
namespace App;
use Illuminate\Database\Eloquent\Collection;
use Illuminate\Database\Eloquent\Model;
class PaymentOption extends Model
{
protected $table = 'payment_option';
public $timestamps = false;
protected $fillable = ['payment_option_code', 'payment_option_name'];
public function setCodeAttribute($value)
{
$this->attributes['payment_option_code'] = $value;
}
public function getCodeAttribute()
{
return $this->payment_option_code;
}
public function setNameAttribute($value)
{
$this->attributes['payment_option_name'] = $value;
}
public function getNameAttribute($value)
{
$this->payment_option_name;
}
}
As you can see, I have weird column names. I need mutators cause I will be accepting variables without the prefix payment_option.
Now, I do it in my controller like so:
<?php
namespace App\Http\Controllers;
use App\PaymentOption;
use App\Http\Requests\PaymentOptionRequest;
class PaymentOptionController extends Controller
{
private $paymentOption;
public function __construct(PaymentOption $paymentOption)
{
$this->paymentOption = $paymentOption;
}
public function create(PaymentOptionRequest $request)
{
$paymentOption = $this->paymentOption->fill($request->validated());
dump($paymentOption);
return response()->json([]);
}
}
When I tried to use the fill() it doesn't call the mutators. But when I tried to set it 1 by 1 it worked like so:
$paymentOption->code = $validated['code'];
Why is that so?
Thanks!

fill does loop on the input data that are in your $fillable array
public function fill(array $attributes)
{
$totallyGuarded = $this->totallyGuarded();
foreach ($this->fillableFromArray($attributes) as $key => $value) {
$key = $this->removeTableFromKey($key);
// The developers may choose to place some attributes in the "fillable" array
// which means only those attributes may be set through mass assignment to
// the model, and all others will just get ignored for security reasons.
if ($this->isFillable($key)) {
$this->setAttribute($key, $value);
} elseif ($totallyGuarded) {
throw new MassAssignmentException(sprintf(
'Add [%s] to fillable property to allow mass assignment on [%s].',
$key, get_class($this)
));
}
}
return $this;
}
hence, you need to add 'code' and 'name' to the fillable array to have them assigned by fill

With latest realese of laravel 8 there is a change in implementation of fill. In laravel older version fill method does work for mutator and database column both. But in laravel 8 implementation of fill method is changed now fill also check if the key given in an array to fill method is a database column or not.
For example if you have database column name user_id and mutator name is user it will not work with laravel 8. It does work for the older version of laravel.
If the $guarded array contains at least one column/key, then that Eloquent Model goes into a strict mode where it can only be filled with values for valid database columns. here is the test is written in the official codebase for that(link to test).
To solve the problem use forceFill. That will solve your problem.
