Python Django-将不同模型的信息显示到同一HTML模板中

我正在使用Django和MySQL数据库 因此，我知道views.py中的1个视图与1个HTML模板相关联，并且我无法将2个不同的视图与同一个模板相关联。 我试图创建一个“关于”视图，其中包含关于我的数据库的一些统计信息。 不幸的是，它不起作用

以下是我迄今为止为“关于”的观点所做的工作：

这是在我的终端中返回的错误：

我的观点的语法对我来说似乎很好

有人建议我应该像这样在我的视图函数中添加“poll_id”：

def about(request,poll_id):

这是什么“民意测验”？这是从哪里来的

如果有人知道发生了什么，我将非常感谢您提供详细的答案/解决方案，因为我是Django的初学者。

您缺少逗号：

context = {
    'namelist': namelist,
    'pdbcount': pdbcount,
    'structcount': structcount
}

有人跑得真快！非常感谢你的回答，我觉得自己好笨。。。

def about(request,poll_id):

context = {
    'namelist': namelist,
    'pdbcount': pdbcount,
    'structcount': structcount
}
