title: django redirecting not working properly
body: <p>I'm making a simple vote class, where a user can vote up or vote down an answer. I don't want this function to return anything,as the vote for every user is created when he votes.
  The problem is that my redirection, or empty return gives me an error like: The page isn't redirecting properly from browser.</p>
  
  <p>My code:</p>
  
  <pre><code>def vote_answer_down(request,id):
     answer = Answer.objects.get(pk = id)
     VoteDownAnswer.objects.create(answer = answer, voted_down_by = request.user) 
  
     return HttpResponseRedirect('.') #or return (without httpresponse),gives the same
  </code></pre>
  
  <p>where am i wrong? 
  Thanks!</p>
