Question

在MongoDB教程（http://django-mongodb-engine.readthedocs.org/en/latest/tutorial.html）之后，我在名为＆＃39;教程的应用程序中有一个名为Post的模型。＆＃39;我安装了应用程序以及djangotoolbox：

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',
    'tutorial'
)

我有以下连接设置，其中包含在MongoLab上设置的名称，用户和密码：

DATABASES = {
    'default': {
       'ENGINE': 'django_mongodb_engine',
       'NAME': '*****',
       'USER': '*****',
       'PASSWORD': '******',
       'HOST': 'ds047720.mongolab.com',
       'PORT': '47720' 
    }
}

当我通过SSH连接到我的主机时，我可以运行manage.py验证，然后发现错误。＆＃34; 0错误。当我进入shell并按照教程创建一个新帖子时，会发生这种情况：

(InteractiveConsole)
>>> from tutorial.models import Post
>>> post = Post.objects.create(
... title='123',
... text='test',
... tags=['a','b']
... )

显然，Django很难连接到数据库，但是我能够使用Mongo Management Studio进行连接。我在这里阅读了类似的教程：http://compsocsci.blogspot.com/2012/02/getting-started-with-django-heroku-and.html 和这里： http://dennisgurnick.com/2010/07/06/bootstrapping-a-django-with-mongo-project/

但我不知道是什么阻止django连接到我的数据库。有没有人用mongodb引擎克服类似的问题？有谁知道我错过了什么？

使用Django MongoDB Engine连接到MongoLab数据库：＆＃34; DatabaseError：超时＆＃34;
