title: Get current user id in devise
body: <p>How do I Get the current user id in my controller using devise?</p>
  
  <p>In my controller I have something like this:</p>
  
  <pre><code>def index
  
  me = current_user
  c = User.find(me)
  @sheets = c.time_sheets
  end
  </code></pre>
  
  <p>I am getting an error say that "Couldn't find User without an ID".</p>
  
  <p>If If I put in a static number in the User.find() it works but of course that is not what I want.  Any help would be greatly appreciated.</p>
  
  <p>thanks!</p>
