【问题描述】：

我正在尝试在我的Django 中使用Mongodb。

下面有settings.py中的连接设置

DEBUG = True
TEMPLATE_DEBUG = DEBUG

ADMINS = (
    # ('Your Name', 'your_email@example.com'),
)


MANAGERS = ADMINS



DATABASES = {
    'default': {
        'ENGINE': 'django_mongodb_engine', 
        'NAME': '',                      
        'USER': '',                      
        'PASSWORD': '',                  
        'HOST': 'localhost',                      
        'PORT': 27017,                      
    }
}

当我尝试运行 python manage.py syncdb 时，我收到如下错误：

Traceback (most recent call last):

django.core.exceptions.ImproperlyConfigured: name must be an instance of basestring

我正在使用 django 1.3

提前致谢

【问题讨论】：

你没有定义数据库
你为什么还要在 Mongo 上使用 syncdb？它将在首次访问时创建集合。

标签： django mongodb django-nonrel django-mongodb-engine

【解决方案1】：

我从未将 mongodb 与 django 一起使用，但我会通过跟踪跟踪来尝试一下。您需要在 DB 配置中为 NAME 设置添加一个值

DATABASES = {
    'default': {
        'ENGINE': 'django_mongodb_engine', 
        'NAME': 'foobar',                      
        'USER': '',                      
        'PASSWORD': '',                  
        'HOST': 'localhost',                      
        'PORT': 27017,                      
    }
}

错误被抛出here in pymongo 这是创建around here via django_mongo_engine
