您好我正在使用我的第一个Django应用程序，我遇到了下一个问题：
包含的URLconf'aventus.urls'似乎没有任何内容 其中的模式。如果您在文件中看到有效模式，那么问题就出现了 可能是由循环导入引起的。

我不知道是什么问题，因为在它工作正常之前，但现在我不知道是什么问题，我只从基于视图的视图中的视图中更改我的events / urls.py class，但在文件中注释文件中新视图之前的旧视图。
答案 0 :(得分：2)
回溯显示events/views.py的第97行出现错误：
success_url = reverse_lazy(reverse('events_app:panel'))
为视图设置reverse时，您无法致电success_url。它导致Django在加载url配置之前尝试反转url，这导致“似乎没有任何模式”错误消息。
解决方案是使用reverse_lazy。你有reverse_lazy(reverse(...))没有意义。将其更改为仅使用reverse_lazy：
success_url = reverse_lazy('events_app:panel')
您的第二个错误“视图必须是可调用的”是因为您为媒体文件提供服务的代码使用字符串'django.views.static.serve'。这已过时，不适用于Django 1.10+。将其更新为src：
from django.conf.urls.static import static
urlpatterns = [
# ... the rest of your URLconf goes here ...
] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
答案 1 :(得分：-1)
在base.py中添加
INSTALLED_APPS += ['myapps.events',]
