title: Check if an object exists
body: <p>I need to check if <code>Model.objects.filter(...)</code> turned up anything, but do not need to insert anything. My code so far is:</p>
  
  <pre><code>user_pass = log_in(request.POST)  # form class
  if user_pass.is_valid():
      cleaned_info = user_pass.cleaned_data
      user_object = User.objects.filter(email = cleaned_info['username'])
  </code></pre>
