Codeigniter 4 V 4.5.1 $this->db problem

Then we can get benefit of protected

Code:

    protected $table = 'items';
    protected $primaryKey = 'item_id';
    protected $allowedFields = ['field1', 'field2', 'field3'];

Then:

PHP Code:

public function get_all_items()
    {
        return $this->findAll(); 
    }

    
    public function fetch_single_item($item_id)
    {
        return $this->where('item_id', $item_id)
                    ->first(); 
    }
