Approval function

Hello Django folks

I would like to add the Approval function within my project my views look like this so far:
def view_application(request, application_id):

if request.user.userprofile.is_client:

    application = get_object_or_404(Application, pk=application_id ,job__created_by=request.user)

else:

    application = get_object_or_404(Application, pk=application_id, created_by=request.user)

if request.method == 'POST':

    content = request.POST.get('content')

    if content:

        conversationmessage = ConversationMessage.objects.create(application=application, content=content, created_by=request.user)


        create_notification(request,application.created_by, 'message',extra_id=application.id)

        return redirect('view_application',application_id=application_id)

return render(request, 'view_application.html', {'application':application})
