我最近将Django版本从2.2迁移到3.2，之后登录就停止了。在2.2中，它运行良好。它给出了一个错误：-

这就是我的urls.py的样子-
from django.conf import settings
from django.conf.urls import include, url
from django.contrib import admin
from django.views.generic import RedirectView
from empereon.views import home, security_question, back_to_login
from django.conf.urls.static import static
from django.contrib.auth.decorators import login_required
from allauth.account.views import login
from . import views
from users.views import password_change
from .views import back_to_dashboard, handler404, handler500
from rest_framework_swagger.views import get_swagger_view
urlpatterns = [
# allauth urls.
url(r'^accounts/login', login),
]
这是我正在使用的数据库详细信息
DATABASES = {
'default': {
'ENGINE': 'sql_server.pyodbc',
'NAME': 'db name',
'USER': 'db user',
'PASSWORD': 'password',
'HOST': 'ip',
'PORT': 'port',
'OPTIONS': {
'driver': 'ODBC Driver 17 for SQL Server',
'host_is_server': True,
'unicode_results': True,
'extra_params': 'tds_version=7.0'
},
}
}
它可能与不同的密码哈希方法有关吗？或者在迁移到Django 3.2后，我还需要做其他事情吗。有人能帮我弄清楚问题出在哪里吗？
[更新]我已经在下面发布了解决方案
[根本原因]
django-mssql后端仅支持django 2.2和3.0
【解决方案】
- 安装pyodbc 3.0(或更新版本(
- 安装库mssql-django
pip安装mssql-django
-
将Django应用程序或项目使用的settings.py文件中的ENGINE设置设置为'mssql'：
"引擎"："mssql">
