当我 {% url 'client_detail' client.id %} 时出现 Python Django NoReverseMatch 错误

Question

我知道我的问题对其他人来说似乎很熟悉，但事实并非如此。当我访问我的主页时，我被困在下面的错误中。问题是 {% url 'client_detail' client.id %}。我很确定我做得对，但它没有发生。

NoReverseMatch 在 / 未找到带有参数 '('',)' 的 'client_detail' 的反向操作。尝试了 1 种模式：['client/(?P[0-9]+)/$']

非常感谢任何帮助

查看您的 crm/crm_home.html 文件并修复如下：<td><a href="{% url 'client_detail' i.id %}">{{i.client_name}}</a></td>
