尝试在 Django 中查看用户配置文件，但在搜索 URL 时找不到页面

Question

我正在尝试使用 Detail CBV 查看我网站的用户配置文件。下面是 views.py、urls.py、models.py 和 profile.html.

的代码

存在一个用户名为 "brian_weber" 的用户，但由于某种原因，当我导航到此 link 时：http://0.0.0.0:8000/accounts/profile/brian_weber 找不到该页面。我的应用名为 "accounts"。

如果有人能给我指出正确的方向，让视图与 url 一起显示，那将不胜感激！我搜索了 Stack Overflow，但没有任何效果。

提前致谢，

布莱恩

你的错误很小，url中提供的配置文件正则表达式，(?P<username>[a-zA-Z0-9]+)不匹配brian_weber，因为_.

您也可以简单地更新正则表达式以匹配 _。

username_regex = r'[a-zA-Z0-9_]+'

urlpatterns = [
    url(r'^logout/$', views.logout_view, name="logout"),
    url(r'^signup/$', views.SignUp.as_view(), name="signup"),
    url(r'^profile/(?P<username>{username})$'.format(username=username_regex), 
        views.UserProfile.as_view(), 
        name="profile"),
    url(r'^profile/update/(?P<username>{username})$'.format(username=username_regex),
        views.UserProfileUpdate.as_view(), 
        name="update_profile"),
]
