Django> SyntaxError at/register/

Question

我正在設計這個應用程序，遇到了一個不尋常的錯誤，試圖修復，但我不能看到錯誤出現在哪裏。我一直在比較代碼，看看我是否可以發現錯誤，但是這兩個代碼相同的只是我的代碼不能正常工作

本教程從這裏走過http://hackedexistence.com/project/django/video7-userauthentication-2.html

你有2 else:條件。這是無效的語法。轉到您提供的鏈接正在製作縮進錯誤。它應該是這樣的。其他內部if-else和其他外部if-else。

if request.method == 'POST': 
      form = RegistrationForm(request.POST) 
      if form.is_valid(): 
        user = User.objects.create_user(username=form.cleaned_data['username'], email = form.cleaned_data['email'], password = form.cleaned_data['password']) 
        user.save() 
        drinker = Drinker(user=user, name=form.cleaned_data['name'], birthday=form.cleaned_data['birthday']) 
        drinker.save() 
        return HttpResponseRedirect('/profile/') 
      else: 
        return render_to_response('register.html', {'form': form}, context_instance=RequestContext(request)) 
    else: 
      ''' user is not submitting the form, show them a blank registration form ''' 
      form = RegistrationForm() 
      context = {'form': form} 
      return render_to_response('register.html', context, context_instance=RequestContext(request))
