如何将createview中创建的对象传递给django中的updateview

from django.views.generic.edit import CreateView

class MyCreateView(CreateView):
    model = MyModel
    form_class = MyForm
    template_name = 'my_template.html'
    success_url = '/success/'

    def form_valid(self, form):
        self.object = form.save()  # 保存对象
        return super().form_valid(form)

from django.urls import reverse

class MyCreateView(CreateView):
    # ...

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

from django.views.generic.edit import UpdateView

class MyUpdateView(UpdateView):
    model = MyModel
    form_class = MyForm
    template_name = 'my_template.html'
    success_url = '/success/'

    def get_object(self, queryset=None):
        return self.model.objects.get(pk=self.kwargs['pk'])
