  <p>But then, I can't see <code>nomor_nasabah</code> attribute in the options here:</p>

  <p>FYI, that <code>nomor_nasabah</code> is a <code>foreign key</code> from another table.</p>
  
  <p>Why is <code>nomor_nasabah</code> property not showing ? where did I go wrong ?</p>
  
  <p>update :</p>
  
  <p>here is my model, and there's no <code>include foreign key</code>

  <p><code>tabungan</code> attributes are : <code>nomor_tabungan</code> , <code>nomor_nasabah</code>, <code>saldo</code></p>
