Python 将Django连接到MongoLab数据库

我目前正在运行Django 1.4.3，我想连接我自己在MongoLab中创建的数据库，与我的Django网站进行对话。我已经尝试了很多关于如何实现这一点的教程；我在Django settings.py文件中遇到的问题是，由于无法连接，我的数据库设置不正确。我是Django和MongoDB的新手，所以如果有任何帮助，我将不胜感激

以下是我遵循的教程之一：

注：我使用的是Mac电脑，如果这很重要的话，我会用终端来编程

这里是my settings.py中的问题区域most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：

您需要配置设置文件中的值。正如您所看到的，它们大部分是空字符串。MongoLab将在您创建的数据库主页上为您提供所需的所有连接信息

似乎是个bug

检查

如果你点击链接，开发者会说：

mongodb引擎目前不支持django 1.4。所以，坚持下去 1.3

这是昨天的评论。就是这样，您使用的Django版本不兼容。

您可以发布您的settings.py和您的完整错误吗？尽管它主要是从Djangopost错误消息自动生成的，但刚刚发布了，请您可以发布您的settings.py和您的完整错误吗？尽管它主要是从Djangopost错误消息自动生成的，请把它们拿出来，我有所有这些正确的值，我只是无法通过django_mongodb_引擎连接。我不知道为什么它无法连接。你能发布一条错误消息吗？你能处理stacktrace吗？隐藏所有密码该文件是用新项目自动创建的。该文件是完全空白/空的。关于错误消息中引用的文件msg:build/bdist.macosx-10.8-intel/egg/django\u mongodb\u engine/\uuuuu init\uuuuu.py，我发布了它，但在从教程链接下载后，我也没有修改它。我取出了它们，我有所有这些正确的值，我无法通过django_mongodb_引擎连接。我不知道为什么它无法连接。你能发布一条错误消息吗？你能处理stacktrace吗？隐藏所有密码该文件是用新项目自动创建的。该文件是完全空白/空的。关于错误消息中引用的文件msg:build/bdist.macosx-10.8-intel/egg/django\u mongodb\u engine/\uuuu init\uuuu.py，我发布了它，但在从教程链接下载后，我也没有修改它。

    # It might be irritating that django-mongodb-engine registers itself as an app,

    # 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.
