如何在Django通用视图中访问URL的命名组?

您可以覆盖get_form_kwargs或get_initial,具体取决于将实例传递给表单的方式:

class MyView(CreateView):
    def get_form_kwargs(self):
        """Return the keyword arguments for instantiating the form."""
        kwargs = super().get_form_kwargs()
        kwargs['foo'] = Foo.objects.get(id=self.kwargs['foo_id'])
        return kwargs

或

class MyView(CreateView):
    def get_initial(self):
        """Return the initial data to use for forms on this view."""
        initial = super().get_initial()
        initial['foo'] = Foo.objects.get(id=self.kwargs['foo_id'])
        return initial
