【问题描述】：
我正在尝试在我的导航栏中创建一个“编辑设置/查看个人资料页面”下拉项目。该功能在从下拉列表调用之前正在工作，现在抛出 NoReverseMatch 错误，如下所示：
未找到带有参数 '('',)' 的 'show_profile_page' 的反向操作。尝试了 1 种模式：['subs/(?P[0-9]+)/profile/\Z']
我很难理解为什么当我在其他模板中调用此 url 时会出现此错误，但现在我尝试将其放入下拉列表中，我得到了这个。我应该在views.py 中进行反向调用吗？将不胜感激任何指针...

我尝试了以下方法：
- 检查错别字
- 通过添加“/”作为后缀更改了 urls.py
- 删除了 user.profile.id 以查看是否引发错误
【问题讨论】：
-
user.profile.id来自哪里？ -
根据您的错误消息，
user.profile.id似乎传递的是一个空字符串，而不是反向匹配所期望的 int。您能否分享您链接到 User 的配置文件模型并确保它具有有效值？同样关于您的最后一点，删除user.profile.id仍然会引发错误，因为需要一个 int 。 -
@shriakhilc 添加了我的 models.py。
-
@SunderamDubey 添加了 models.py
-
0 注意：因为我一直在搞乱，我发现如果我只用一个整数替换“user.profile.id”作为参数，比如这个显示配置文件页面，它会让我转到该页面，然后让我去到表格并填写它，一切正常，但显然这不起作用，因为它将表格内容发送到那里列出的任何 id，而不是适当的 id。
