我正在尝试查看每个客户的订单，但出现此错误

这是错误

File "C:\Users\user\anaconda3\envs\myenv\lib\site-packages\django\urls\resolvers.py", line 694, in _reverse_with_prefix
    raise NoReverseMatch(msg)
django.urls.exceptions.NoReverseMatch: Reverse for 'update_order' with arguments '('',)' not found. 1 pattern(s) tried: ['update_order/(?P<pk>[^/]+)$']

当我尝试访问视图以查看有关客户订单的详细信息时收到错误消息。不知道是不是数据库中的订单有问题，还是跟模板中的路由声明有关

有人可以帮我弄这个吗？
