Newbie struggling with a 'Call to undefined method' error in Laravel Eloquent ORM query

Hi everyone, I'm quite new to Laravel development and struggling with a 'Call to undefined method' error while trying to fetch data using Eloquent ORM.

I'm not sure what I'm doing wrong with the query, so here's a simplified version of my code and the error I'm encountering:

// My Model
class Product extends Model
{
    protected $fillable = ['name', 'price'];
}

// My Controller Method
public function showActiveProducts()
{
    $products = Product::where('is_active', true)->get_active(); // This line causes the error
    return view('products.index', compact('products'));
}

// The Error Log
Call to undefined method App\Models\Product::get_active()
in file .../app/Http/Controllers/ProductController.php on line X

Could anyone please advise on how to correctly structure this Eloquent ORM query? Thanks in advance!
