嘗試在Django中查看用戶配置文件，但在搜索URL時未找到頁面

Question

我正在嘗試使用Detail CBV查看我的網站的用戶配置文件。以下是views.py，urls.py，models.py和profile.html的代碼。

用戶以用戶名「brian_weber」存在，但由於某種原因導航到此鏈接時：http://0.0.0.0:8000/accounts/profile/brian_weber未找到該頁面。我的應用程序被稱爲「帳戶」。

如果有人能指出我在正確的方向，讓視圖顯示與網址，這將不勝感激！我已經搜索了堆棧溢出，但沒有任何工作，我試過。

由於提前，

你的錯誤是非常小的，在網址爲配置文件提供的正則表達式，(?P<username>[a-zA-Z0-9]+)不會因爲_匹配brian_weber。

您也可以簡單地更新正則表達式以匹配_。

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"), 
]
