django - ListView 调用 `get_template_names` 而不调用它

Question

我正在阅读 Django 源代码ListView： django/list.py

class MultipleObjectTemplateResponseMixin(TemplateResponseMixin):
    template_name_suffix = '_list'
    def get_template_names(self):
       try:
            names = super().get_template_names()

class ListView(MultipleObjectTemplateResponseMixin, BaseListView):
    """
    Render some list of objects, set by `self.model` or `self.queryset`.
    `self.queryset` can actually be any iterable of items, not just a queryset.
    """

当我定义ListView时，template_name自动分配

class IndexView(generic.ListView):
    pass

MultipleObjectTemplateResponseMixin我认为应该有一个分配步骤

class MultipleObjectTemplateResponseMixin(TemplateResponseMixin):
    template_name_suffix = '_list'
    def get_template_names(self):
       try:
            names = super().get_template_names()
            ....
    template_name = self.get_template_names()

它如何调用get_template_names而不调用它？
