title: Monitor usage of a certain database field
body: <p>I have a nasty problem. I want to get rid of a certain database field, but I'm not sure in which bits of code it's called. Is there a way to find out where this field is used/called from (except for text searching the code; this is fairly useless seeing as how the field is named 'email')?</p>
  
  <p>Cheers</p>
