Redirect to next parameter in Django 1.5

Question

I have an input field <input type="hidden" name="next" value="{{ next }}" />, but it wont replace {{ next }} with the value of the GET parameter. I can't find how to replace the value.

My view

class LoginView(FormView):
    form_class = AuthenticationForm
    redirect_field_name = REDIRECT_FIELD_NAME
    template_name = 'user/login.html'

    @method_decorator(csrf_protect)
    @method_decorator(never_cache)
    def dispatch(self, *args, **kwargs):
        return super(LoginView, self).dispatch(*args, **kwargs)

    def form_valid(self, form):
        login(self.request, form.get_user())
            return super(LoginView, self).form_valid(form)

    def get_success_url(self):
        if self.success_url:
            redirect_to = self.success_url
        else:
            redirect_to = self.request.REQUEST.get(self.redirect_field_name, '')

        if not redirect_to:
            redirect_to = resolve_url(settings.LOGIN_REDIRECT_URL)

        return redirect_to

Override method get_context_data on class LoginView.

def get_context_data(self, **kwargs):
    context = super(LoginView, self).get_context_data(**kwargs)
    context['next'] = self.request.REQUEST.get('next')
    return context

This assumes that the GET parameter will have the next url where user should be redirected in param next. So, request should be of form localhost.com/login?next=/accounts/
