How to make the django redirects a user to the page I need?

How to make the django redirects a user to the page I need?

I have a web app. For example a user is on a page with an address local:8000/detail-order/18. This page is detail info of the order 18. On this page is link to edit this order. When a user clicks this link a order editing form shows up. When a user writes in this form and click the submit button, he has an error. I whould like that a user goes back to local:8000/detail-order/18.

You can override the .get_success_url(..) method [Django-doc] and thus inject parameters:

from django.urls import reverse

class UpdateOrderView(CustomSuccessMessageMixin, UpdateView):
    model = Order
    template_name = 'orders.html'
    form_class = OrderForm
    success_msg = 'Изменения сохранены'

    def get_context_data(self, **kwargs):
        kwargs['update'] = True
        return super().get_context_data(**kwargs)

    def get_success_url(self):
        return reverse('detail_order', kwargs={'pk': self.object.pk})
