将Mongodb与Django连接起来

问题描述 投票：0回答：5

我正在尝试将mongodb与django连接，但我收到此错误

ImproperlyConfigured: 'djongo' isn't an available database backend.
Try using 'django.db.backends.XXX', where XXX is one of:
    'mysql', 'oracle', 'postgresql_psycopg2', 'sqlite3'

我看过帖子，但他们都老了，没帮我。我用studio 3T创建了mongodb数据库，数据库名是New DataBase用户是gsc-30310端口是27017主机是localhost

我使用的版本是：

python3

Django==2.1.1
mongoengine==0.15.3
pymongo==3.7.1

这是我的settings.py文件，请告诉我如何设置新版本的django和python 3.谢谢

在django视图中使用pymongo：

client = pymongo.MongoClient(MONGO_URI)
mongodb = client[MONGO_DB_NAME]
...
class MongoClassView(View):
   def post(request):
       ...
       mapped_data = {'name': 'John'}
       mongodb.get_collection('mycollection').insert(mapped_data)
       return JsonResponse({})

希望这可以帮助

您可以尝试以下步骤将django 2.0或更多版本与MongoDB数据库连接：

1）为django 2.0安装另一个版本

pip install -e git+https://github.com/MongoEngine/django-mongoengine.git#egg=django-mongoengine

2）在您的设置文件中添加这些：

from mongoengine import *

'django_mongoengine', // Add this line to installed app

MONGODB_DATABASES = {
"default": {
"name": '<db_name>',
"host": 'localhost',
"password": '',
"username": '',
"tz_aware": True, # if you using timezones in django (USE_TZ = True)
},
}

您可以找到查询数据库here的详细信息

Django适用于PostGreSQL，MySQL等关系数据库。每个django设置都需要使用'default'配置定义数据库配置，它还需要数据库各自的引擎，如PostGreSQL的psycopg2，MySQL的mysqlclient - 如果你有多个数据库配置，那么你需要使用数据库路由器检查here作为参考。对于MongoDB - 它是一个NoSql数据库，Django官方不支持如果你真的需要使用MongoDB在视图中创建一个mongoengine配置，你可以在settings.py中定义mongo凭据

首先感谢您在这个问题上的答案和支持。

我同意Sanchit和shreesh katti的答案，我们可以使用mongoclient和mongoengine连接MongoDB，两者都很好用。

我找到了另一种方式，有一个开源项目djongo，我使用djongo连接MongoDB数据库。 djongo的主要好处是它可以让你使用django提供的所有东西（例如models.Model）。

这里是djongo GitHub页面https://github.com/nesdis/djongo的链接

这是我们需要使用djongo settings.py的设置

DATABASES = {
'default': {
    'ENGINE': 'djongo',
    'NAME': 'MyDB',
}

}

使用mongoengine和djongo连接。在settings.py文件中进行以下更改

mongoengine.connect(
        db=config.main_db,
        host=config.host,
        #username=config.username_admin,
        #password=config.password_admin,
        #authentication_source=config.authSource_admin,
        #authentication_mechanism=config.authenticationMechanisms)



DATABASES = {
        'default': {
            'ENGINE': 'djongo',
            'NAME': config.main_db,
            # 'USER': config.username_admin,
            # 'PASSWORD': config.password_admin,
            # 'HOST': config.host,
            # 'PORT': config.port,
        }
    }
