  <p>I know how to get the file extension in the form, but how can I get this in the view. I'm aware I can access the file thru - </p>
  
  <pre><code>docfile=request.FILES['docfile']
  </code></pre>
  
  <p>View - </p>
  
  <pre><code>from django.shortcuts import render_to_response

  def list(request):
      # Handle file upload
      if request.method == 'POST':
          form = DocumentForm(request.POST, request.FILES)
          if form.is_valid():     
              docfile=request.FILES['docfile']
  
              # Redirect to the document list after POST
              return HttpResponseRedirect(reverse('myproject.myapp.views.list'))
      else:
          form = DocumentForm()  # A empty, unbound form
  
      # Load documents for the list page
      documents = Document.objects.all()
  
      # Render list page with the documents and the form
      return render_to_response(
          'list.html',
          {'documents': documents, 'form': form},
          context_instance=RequestContext(request)
      )
