title: Django forms: reload view after post
body: <p>I have the following view code:</p>
  
  <pre><code>def activate( request = '', actkey = "" ):
      message = ""
      if len( actkey ) != 40:
          message += str( len(actkey))
          if request.method == 'POST':
              form = ActivateForm( request.POST )
              if form.is_valid():
                  actkey = request.POST['actkey']
                  activate( '', actkey )
          else:
              form = ActivateForm()
      else:
          profile = userprofile.objects.get( actkey = actkey )
          user = User.objects.get( id = profile.user_id )
          user.is_active = True
          user.save()
          profile.actkey = ""
          profile.save()
          message += "Uw account is succesvol geactiveerd."
          return render_to_response( 'profile/register.html', { 'message' : message } )
      return render_to_response( 'profile/register.html', { 'message' : message, 'form' : form } )
  </code></pre>
  
  <p>What it does is simple, when the activation key is given through the URL, it goes to:
  profile = userprofile.... etc.
  But when it's not given it loads the django form so the user can type it's activation code (all works well so far)
  But when the user posts his activation key it comes in the <code>if len( actkey ) != 40:</code>
  That shouldn't happen because the activation key is 40... But since it shows the form again, but activates the user as well i get unwanted behavior... </p>
  
  <p>How can i fix this?</p>
  
  <p>Thanks for the help </p>
