【中文标题】错误问题 * 发生服务器错误。请联系管理员 * django rest framework【英文标题】：Problem with the error * A server error occurred. Please contact the administrator * django rest framework 【发布时间】：2020-10-25 09:44:34 【问题描述】：

我正在尝试测试一些基本的支持功能，但我似乎遇到了这个错误发生了服务器错误。请在尝试连接到本地主机http://127.0.0.1:8000 或http://127.0.0.1:8000/sise/ 时联系管理员。

起初我有这个错误显示 django.core.exceptions.ImproperlyConfigured: The included URLconf 'Dashboard_sise.urls' 似乎没有任何模式。如果您在文件中看到有效模式，则问题可能是由循环导入引起的。但是在我在设置文件 ROOT_URLCONF = 'Dashboard_sise.urls' 中评论了这一行之后，错误发生了变化发生服务器错误。请联系管理员。

谁能帮我解决这个问题，我已经尝试更改 urls.py 文件中的 urlpatterns 但它不起作用，我还尝试操作设置文件中的 MIDDLEWARE 部分但没有任何改变。

这是 Dashboard_sise.urls 代码

from django.contrib import admin
from django.urls import include, path

urlpatterns = [
    path('admin/', admin.sites.urls),
    path('sise/', include('Dashboard.urls')),
]

这是 Dashboard.urls 代码

from rest_framework.routers import DefaultRouter
from Dashboard.views import *

router = DefaultRouter()

router.register(r'accee', AcceeViewSet, basename='accee')
router.register(r'rapport', RapportViewSet, basename='rapport')
router.register(r'prise_fonction', PointageUtilisateurViewSet, basename='prise_fonction')

urlPatterns = router.urls

最后是设置文件

提前谢谢你

【问题讨论】：

第一个错误可能是主要问题，它表示可能存在循环导入。也许您可以在 urls 文件中包含完整的代码。我编辑了代码，现在我只尝试在 Dashboard.urls 代码中测试这 03 个 url 【参考方案1】：

如果有人遇到同样的错误，我会回答这个问题。我的数据库结构有问题..在models.py文件中实现的模型和创建的数据库不匹配，所以它一直向我显示这个错误......一旦我修复了models.py文件，它就一切正常

【参考方案2】：

也许这就是原因。
