title: How to exclude entity field from returned by controller JSON. NestJS + Typeorm
body: <p>I want to exclude password field from returned JSON. 
  I am using NestJS and Typeorm. </p>
  
  <p>The solution provided on <a href="https://stackoverflow.com/questions/43726739/is-it-possible-to-protect-a-property-and-exclude-it-from-select-statements#44444496">this question</a> doesn't work for me or in NestJS. I can post my code if needed.
  Any other ideas or solutions? Thanks.</p>
