Question

我正在django中创建一个应用程序，我想从mongolab获取数据。但是，我不知道如何将mongolab连接到django。我把mongodb连接到django，但现在我想连接mongolab。怎么做？

我在我的setting.py文件中使用过它，

INSTALLED_APPS = (
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.sites',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'django.contrib.admin', 
    'django.contrib.admindocs',
    'djangotoolbox',
    'app'
)

在DATABASE：中，

DATABASES = {
    'default': {
       'ENGINE': 'django_mongodb_engine',
       'NAME': '*****',
       'USER': '*****',
       'PASSWORD': '******',
       'HOST': 'ds129469.mongolab.com',
       'PORT': '26469' 
    }
}

运行命令后，运行python manage.py runserver 我得到以下错误，

life@life-All-Series:~/mongo/env1/project7/project$ python manage.py runrver
/home/life/.local/lib/python2.7/site-packages/djangotoolbox/db/utils.py:1: RemovedInDjango19Warning: The django.db.backends.util module has been renamed. Use django.db.backends.utils instead.
  from django.db.backends.util import format_number

如何将mongolab连接到django？
