getAttribute in laravel 5.5

Is something has been changed?

in trait i created for eloquent model i can't use getAttribute($key) - it is completly skipped . However setAttibute($key, $value) works like charm

trait SomeTrait
{
    public function getAttribute($key)
    {
            return "it just not working";
    }

    public function setAttribute($key, $value)
    {
        if (in_array($key, $this->specialPropertyArray)) {
          
            return parent::setAttribute($key, someFunctionOn($value));
        }

        return parent::setAttribute($key, $value);
    }


}

In addition i have to say i have no custom accessors for my models

Hmmm, no nothing in this flow has changed.

Illuminate\Database\Eloquent\Model.php line 1260

    public function __get($key)
    {
        return $this->getAttribute($key);
    }

The magic get function will use getAttribute to get any key that doesnt exist as a public property on the model itself.

So unless the attribute you're trying to get from the model is also in a public var, or you have a custom magic __get method in your model, this should simply work.

I have tried this on so many ways

->relation()-first()
->relation
->find
->where()->get()->first()

and sooo on.... and there is something wrong with it

this function works like a charm in all above ways

 public function getFieldAttribute($value)
{
        return someFunction($value);
}

this never works

public function getAttribute($key)
{
        $value = parent::getAttribute($key);

        return someFunction($value);
}

Does someone encounter this problem before?

For anyone who one day will be looking for an answer.Method getAttribute() is fired only when you call property like $model->property. If you returning collection which later is converted to array method that is used to do this is toArray() so to my Trait i had to add this method

public function toArray()
{
    $array = parent::toArray();

    foreach ($array as $key => $attribute) {
        if (in_array($key, $this->specialPropertyArray)) {
            $array[$key] = someFunction($attribute);
        }
    }
    return $array;
}
