Question

我们使用Django 1.7，Mongoengine 0.8.7，MongoDB 2.4.7和Python 3.4构建了我们的环境。

我们安装了django-rest-framework，但是当我们尝试运行网站示例时，我们收到以下错误：

ImproperlyConfigured at /users/

settings.DATABASES is improperly configured. Please supply the ENGINE value. Check settings documentation for more details.

Request Method:         GET
Request URL:         http://localhost:8000/users/
Django Version:         1.7
Exception Type:         ImproperlyConfigured
Exception Value:         

settings.DATABASES is improperly configured. Please supply the ENGINE value. Check settings documentation for more details.

'/Users/user_name/Development/projects/current_project/lib/python3.4/site-packages']

根据我们找到的文档，这是我们在settings.py中所做的更改：

import mongoengine

DATABASES = {
    'default': { 
    'ENGINE': 'django.db.backends.dummy',
  }
}

mongoengine.connect('database_name', username='root', password='password')


SESSION_ENGINE = 'mongoengine.django.sessions'
SESSION_SERIALIZER = 'mongoengine.django.sessions.BSONSerializer'

对于我们所看到的，如果我们通过mongoengine.connect方法连接，则不应忽略ENGINE参数，但我们发现此错误。有谁知道我们如何解决它？

Answer 1

我在settings.py文件的末尾使用了mongodb设置，如下所示

# Mongodb settings

AUTHENTICATION_BACKENDS = (
    'mongoengine.django.auth.MongoEngineBackend',
)

MONGO_DATABASE_NAME = 'prod'


MONGOENGINE_USER_DOCUMENT = 'mongoengine.django.auth.User'

SESSION_ENGINE = 'mongoengine.django.sessions'
SESSION_SERIALIZER = 'mongoengine.django.sessions.BSONSerializer'

from mongoengine import connect
connect(MONGO_DATABASE_NAME)

Answer 2

将此添加到settings.py：

AUTHENTICATION_BACKENDS = (
    'mongoengine.django.auth.MongoEngineBackend',
)

也许这可以帮到你。

Answer 3

经过一番研究，我们找到了解决问题的方法。

我们没有按照http://www.django-rest-framework.org/上可以找到的示例，而是遵循Quickstart guide。按照本指南，我们已经解决了我们的问题。

非常感谢所有答案！
