title: where to put django signal receiver code, spread them over multiple files?
body: <p>I've put my signal receiver code in the respective model file.</p>
  
  <p>However, signal receivers keep growing and I'd like to separate them over multiple files.</p>
  
  <p>I haven't seen discussion on where to put signal receiver codes.  </p>
  
  <p>(makes me suspect that I'm not supposed to make many signal receivers maybe?)</p>
