设置MongoDB + Django [英] Setting up MongoDB + Django

问题描述

我是Mongo DB和Django的新手.我一直在尝试使用Mongo DB作为Django的主要数据库.我已经按照以下链接安装了MongoDB和Django-nonrel:

I am new to Mongo DB and Django. I've been trying to use Mongo DB as my primary Database for Django. I've installed MongoDB and Django-nonrel as per the following link:

Django-MongoDB设置

我正在使用的django-nonrel版本是1.7.克隆到它的链接:

The version of django-nonrel, i am using is 1.7. Clone link to it:

pip安装git + https://github.com/django-nonrel/django@nonrel-1.7

完成所有步骤后，django项目文件中的settings.py看起来像这样:

After following all steps, my settings.py in the django project file looks something like this:

DATABASES = {
    'default': {
        'ENGINE': 'django_mongodb_engine',
        'NAME': 'blink',
        'USER': '',
        'PASSWORD': '',
        'HOST': '127.0.0.1',
        'PORT': 1234,
    }
}

INSTALLED_APPS = (
    'djangotoolbox',
)

但是在使用以下命令运行manage.py时:

But while running the manage.py using the following command:

python manage.py runserver

我遇到这样的错误，

我无法理解该错误是什么.有人可以帮忙吗?

I am not able to understand what the error is. Can somebody please help.?

推荐答案

似乎您正在使用Python3.但是 django-mongodb-engine ，在其上的 django-nonrel 取决于，甚至还不支持Python 3.

It seems that you are using Python 3. But django-mongodb-engine, on which django-nonrel depends, doesn't even support Python 3 yet.

上面的语法错误实际上在py3中有效，但在py2中无效.因此错误.

The syntax error above is actually valid in py3, but not in py2. Thus the error.

也许您应该考虑在该项目中使用py2.

Perhaps you should consider using py2 for this project.
