title: Django `object of type 'instancemethod' has no len()`
body: <p>I have a following code in django:</p>
  
  <pre><code>def index(request):
      template_name = 'desks.html'
  
     # query = Desk.objects.all()
  
      desk_list = Desk.objects.all
  
      paginator = Paginator(desk_list, 5)
      page = paginator.page(1)
  
      return render_to_response(template_name, {'desk_list': page}, )
  </code></pre>
  
  <p>Unfortunately, I get the following error:
  <code>object of type 'instancemethod' has no len()</code></p>
  
  <p>At my model, I have defined only attributes.</p>
  
  <p>Any idea what a mistake it can be?</p>
