我目前正在运行Django 1.4.3,我想连接我自己的数据库(在MongoLab中创建)与我的Django网站交谈。我已经尝试过如何实现这一目标的大量教程;我在Django settings.py文件中遇到的问题是我的数据库设置不正确(由于无法连接)。我是Django和MongoDB的新手,所以任何帮助都会受到赞赏。
以下是我遵循的教程之一:http://www.allbuttonspressed.com/blog/django/2010/05/MongoDB-backend-for-Django-nonrel-released
注意:如果重要的话,我正在使用Mac并使用终端对所有内容进行编程。
这是我的settings.py中的麻烦区域(大多数是由Django自动生成的)
DATABASES = {
'default': {
#'ENGINE': 'django_mongodb_engine', ### This wasn't working ###
'ENGINE': '',
'NAME': '', # Or path to database file if using sq$
'USER': '', # Not used with sqlite3.
'PASSWORD': '', # Not used with sqlite3.
'HOST': '', # Set to empty string for localhost. N$
'PORT': '', # Set to empty string for default. Not$
}
}
以下是错误消息:

# It might be irritating that django-mongodb-engine registers itself as an app,
# and I think this is worth an explanation - so here you go:
# django-mongodb-engine provides a way to set MongoDB-specific options for a
# certain model via the 'MongoMeta' class/attribute (similar to the Django-style
# 'Meta' class). We want those options to be copied into the model's
# '_meta' object, right after the class has been defined.
# For this, we have to listen to the 'class_prepared' signal from
# 'django.db.models.signals'. Because the 'django_mongodb_engine' module gets
# imported as part of the initialization process of Django's ORM ('django.db'),
# we can *not* import anything from 'django.db' in this file (or any other
# submodule that is imported while the ORM initialization) because that would
# get us into recursive import hell which the Python interpreter doesn't allow.
# The only way to make sure certain code is executed after Django's ORM has been
# initialized is registering an app. After initializing itself, Django imports
# all apps defined in the project's 'settings.py' in the order implied by
# iterating over the INSTALLED_APPS list. As we have to make sure that
# django-mongodb-engine is loaded very first, we prepend it to the list.

您需要在设置文件中配置值。如你所见,它们大多是空字符串。 MongoLab将在您创建的数据库的主页上为您提供所需的所有连接信息。

似乎有一个错误。
检查this report。
如果您按照链接,here开发人员说:
mongodb-engine目前不支持django 1.4。所以坚持下去 1.3。
该评论来自昨天。就是这样,你使用的Django版本不兼容。
