<!--      <td><g:link action="show" id="${airports.id}">details</g:link></td>-->

    </tr>
  </g:each>

Answer 1

The var attribute is the name of the iteration variable. Change that from book to airports. Changing airports to airport would make more sense, too, although that’s just an issue of style.
