我正在尝试在Django中使用MongoDB数据库。为此，我将设置更改为此，我在这里使用mlab。
settings.py
DATABASES = {
'default': {
'ENGINE': 'djongo',
'NAME': 'crud-django',
'HOST': 'mongodb://adityakmr:password1@ds231956.mlab.com:31956/',
'USER': 'adityakmr',
'PASSWORD': 'password1'
}
}
但是每次我尝试运行迁移时，都会出现类似这样的错误。我不知道它来自哪里，我已经提供了正确的用户名和密码。 我还使用pip安装了djongo。

在最新版本中，使用客户端连接到数据库。 我希望遵循数据库配置可以解决您的问题。
DATABASES = {
'default': {
'ENGINE': 'djongo',
'ENFORCE_SCHEMA': True,
'LOGGING': {
'version': 1,
'loggers': {
'djongo': {
'level': 'DEBUG',
'propogate': False,
}
},
},

您必须使用USERNAME代替USER
DATABASES = {
'default': {
'ENGINE': 'djongo',
'NAME': 'test_db',
'USERNAME': 'username',
'PASSWORD': 'password',
'HOST': 'host',
'PORT': 27017,
'AUTH_SOURCE': 'test_db',
}
}
