title: Django 1.5 giving error 405 for simple form
body: <p>I made a form for including Auth Groups. But when I post it I get a blank page (url /groups/) with an Error on terminal: <strong>"POST /grupos/ HTTP/1.1" 405 0</strong> This is so weird, when I give refresh I see the list of groups, with nothing added.</p>
  
  <p>=== urls.py</p>
  
  <pre><code>    url(r'^groups/$', login_required(TemplateUtilsListView.as_view(model=Group)), name='group_list'),
  url(r'^groups/add$', login_required(CreateView.as_view(model=Group, form_class=GroupForm, template_name='generic_insert.html')), name='group_create'),
  </code></pre>
