Question

当我在终端上运行Django应用程序时，我收到以下错误：

我的主urls.py文件

^{pr2}$

这是我的Trip应用程序的视图，我在所有url文件中都遵循相同的模式。在

from django.conf.urls import url
from wheredego_service.trip import trip_views
from wheredego_service.trip.itinerary import itinerary_views

urlpatterns =[
url(r'^/(?P<trip_id>[0-9,a-z,_]+)/itinerary', itinerary_views.ListItineraryTripView.as_view()), url(r'^/me', trip_views.ListMyTripsView.as_view()), ]

请帮助解决此错误。在

在一个urls.py文件中，URL模式列表中有一个字符串。这可能是因为您在从patterns(prefix, ...)切换到url()列表时忘记删除前缀

你需要看看你的网址.py找到一些类似的东西：

urlpatterns =[
    '' # <- this is the problem, remove this string
    url(...)
    url(...)
]

不幸的是，我们不可能分辨出问题出在哪个urls.py。您可以尝试逐个注释includes()。如果错误停止，则您已找到导致问题的原因。在

在django1.10中，url检查有了一些改进，check_pattern_startswith_slash不会再失败了，您将得到关于字符串的特定警告。在
