升级Django后，在/ admin /处出现NoReverseMatch错误

Question

将Django项目从1.8升级到2.0后，我尝试登录到管理页面，并收到此错误消息。我可以看到登录页面以及其他管理员链接，例如“ http://159.203.172.178/admin/QI/page/”，但我只能看到首页。

我肯定在这里包括太多代码，因为我现在确实不在问题所在。预先非常感谢。

用于管理员的urls.py：

from django.conf.urls import *
from django.contrib import admin
from django.contrib.admin.views.decorators import staff_member_required
from . import views
from django.urls import path,re_path,reverse,include

app_name="QI"

urlpatterns = [
    path('admin/', admin.site.urls),
]

settings.py：

 import os
 from .settings_secret import *

 BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))

 STATIC_URL = '/static/'

 STATIC_ROOT = os.path.join(BASE_DIR, 'static')

此html文件中包含的review_transcription_lists：

{% extends 'admin/base_site.html' %}

{% load staticfiles %}


{% block extrastyle %}
