Fatal error: Call to a member function query() on a non-object

You should always check to make sure you retrive data from a query!

Code:

public function get_all()
{
    $query = $this->db->query('SELECT * FROM stock_categories');

    if ($query->num_rows() > 0)
    {
        return $query->result();
    }
    else // you have an error - no records returned!
    {
        echo 'ERROR!';
        return FALSE;
    }
}
