Getting error on redirect django

Question

What am I trying to do is

if a user comes with a slug

Case 1

'new' I am either creating a new box for him or fetching his existing empty box and redirecting him based on the slug of the box

Case 2

anything else works fine

URL pattern is

url(r'^box/manage/(?P<slug>.*)/$', login_required(views.ManageBoxView.as_view()), name='manage_box'),

I am getting an error

dict' object has no attribute 'has_header'

class ManageBoxView(TemplateView):
  template_name = "art/manage_box.html"

  def get(self, request, **kwargs):
    if kwargs['slug'] == 'new':
      box = Box.get_or_create_empty_box(self.request.user)
      return redirect('manage_box', slug= box.slug)
    else:
      box = Box.objects.get(slug=kwargs['slug'])
      return {'box': box, 'drafts': box.drafts}

Answer 1

In the else condition of the get method, you are trying to return an object instead of a response. You have to return a response like return render(request, template_name, {'box': box, 'drafts': box.drafts}) instead of return {'box': box, 'drafts': box.drafts} .
