        """
        在视图函数中将模板变量传递给模板是通过给 render 函数的 context 参数传递一个字典实现的，
        例如 render(request, 'blog/index.html', context={'post_list': post_list})，
        这里传递了一个 {'post_list': post_list} 字典给模板。
        在类视图中，这个需要传递的模板变量字典是通过 get_context_data 获得的，
        所以我们复写该方法，以便我们能够自己再插入一些我们自定义的模板变量进去。

        # 首先获得父类生成的传递给模板的字典。
        context = super(IndexView, self).get_context_data(**kwargs)

        # 父类生成的字典中已有 paginator、page_obj、is_paginated 这三个模板变量，
        # paginator 是 Paginator 的一个实例，
        # page_obj 是 Page 的一个实例，
        # is_paginated 是一个布尔变量，用于指示是否已分页。
        # 例如如果规定每页 10 个数据，而本身只有 5 个数据，其实就用不着分页，此时 is_paginated=False。
        # 关于什么是 Paginator，Page 类在 Django Pagination 简单分页。
        # 由于 context 是一个字典，所以调用 get 方法从中取出某个键对应的值。

        paginator = context.get('paginator')
        page = context.get('page_obj')
        is_paginated = context.get('is_paginated')

        # 调用自己写的 pagination_data 方法获得显示分页导航条需要的数据，见下方。
        pagination_data = self.pagination_data(paginator, page, is_paginated)

        # 将分页导航条的模板变量更新到 context 中，注意 pagination_data 方法返回的也是一个字典。
        context.update(pagination_data)

        # 将更新后的 context 返回，以便 ListView 使用这个字典中的模板变量去渲染模板。
        # 注意此时 context 字典中已有了显示分页导航条所需的数据。
