title: Implicit DB Session in Controller
body: <p>Is it bad practice in Play! Framework to define the implicit DB session inside the controller to have less boilerplate?</p>
  
  <pre><code>object MyController extends Controller  {
    implicit val session = DB.createSession
  }
  </code></pre>
  
  <p>I'm not sure about the life cycle of controllers in Play!, can somebody enlighten me?</p>
