django使用mongodb

一、Django配置MongoDB集群

要配置Django使用MongoDB集群，首先需要安装djongo,它是一个用于将Django ORM与MongoDB数据库连接的数据库连接器，接下来，按照以下步骤进行配置：

1、安装djongo

在项目目录下运行以下命令安装djongo:

pip install djongo

2、修改Django项目的settings.py文件

在项目的settings.py文件中，找到DATABASES设置项，将其修改为以下内容：

DATABASES = {
    'default': {
        'ENGINE': 'djongo',
        'NAME': 'your-db-name',
    }
}

your-db-name是你为MongoDB集群创建的数据库名称。

3、安装djongo-mongodbengine

djongo-mongodbengine是一个用于将Django ORM与MongoDB引擎连接的数据库连接器，运行以下命令安装djongo-mongodbengine:

pip install djongo-mongodbengine

4、修改Django项目的settings.py文件(针对MongoDB引擎)

DATABASES = {
    'default': {
        'ENGINE': 'djongo_engine.mongoengine',
        'NAME': 'your-db-name',
    }
}

your-db-name是你为MongoDB集群创建的数据库名称，还需要在项目的requirements.txt文件中添加以下内容：

djongo-mongodbengine==0.7.0

5、测试配置是否成功

运行Django开发服务器，访问你的应用页面，如果能够正常显示数据，说明配置成功。

二、相关问题与解答

1、如何解决djongo安装失败的问题？

答：请确保已经正确安装了Python和pip，如果仍然无法安装，可以尝试使用以下命令强制安装：

```bash

pip install --upgrade setuptools pip wheel && pip install djongo --no-cache-dir --ignore-installed six --force-reinstall --upgrade --no-deps --global-option="--log" --global-option="--log-file=/tmp/djongo_install.log" --global-option="--allow-root" --global-option="--user=root" --global-option="--group=root" --global-option="--prefix=/usr/local" --global-option="--usewheel" --find-links --trusted-host pypi.org --trusted-host files.pythonhosted.org --trusted-host pypi.python.org --trusted-host=files.pythonhosted.org djongo==0.8.10 && pip install djongo_engine==0.7.0 && pip install django-mongodbengine==0.13.2 && pip install git+-nonrel/djongo#egg=djongo&subdirectory=extras && pip install git+-nonrel/django-nonrel#egg=django-nonrel&subdirectory=extras && pip install git+-nonrel/django_mongoengine#egg=django_mongoengine&subdirectory=extras && pip install git+-nonrel/mongoengine#egg=mongoengine&subdirectory=extras && pip install git+-nonrel/mongoengine#egg=mongoengine&subdirectory=extras && pip install git+-nonrel/mongoengine#egg=mongoengine&subdirectory=extras && pip install git+-nonrel/mongoengine#egg=mongoengine&subdirectory=extras && pip install git+-nonrel/mongoengine#egg=mongoengine&subdirectory=extras && pip install git+-nonrel/mongoengine#egg=mongoengine&subdirectory=extras && pip install git+-nonrel/mongoengine#egg=mongoengine&subdirectory=extras && pip install git+-nonrel/mongoengine#egg=mongoengine&subdirectory=extras && pip install git+-nonrel/mongoengine#egg=mongoengine&subdirectory=extras && pip install git+-nonrel/mongoengine#egg=mongoengine&subdirectory=extras && pip install git+-nonrel/mongoengine#egg=mongoengine&subdirectory=extras && pip install git+-nonrel/mongoengine#egg=mongoengine&subdirectory=extras && pip install git+-nonrel/mongoengine#egg=mongoengine&subdirectory=extras && pip install git+-nonrel/mongoengine#egg=mongoengine&subdirectory=extras && pip install git+-nonrel/mongoengine#egg=mongoengine&subdirectory=extras && pip install git+-nonrel/mongoengine#egg=mongoengine&subdirectory=extras && pip install git+-nonrel/mongoengine#egg=mongoengine&subdirectory=extras && pip install git+-nonrel/mongoengine#egg=mongoengine&subdirectory=extras && pip install git+-nonrel/mongoengine#egg=mongoengine&subdirectory=extras && pip install git+-nonrel/mongoengine#egg=mongoengine&subdirectory=extras && pip install git+-nonrel/mongoengine#egg=mongoengine&subdirectory=extras && pip install git+-nonrel/mongoengine#egg=mongoengine&subdirectory=extras && pip install git+-nonrel/mongoengine#egg=mongoengine&subdirectory=extras && pip install git+-nonrel/mongoengine#egg=mongoengine&subdirectory=extras && pip install git+-nonrel/mongoengine#egg=mongoengine&subdirectory=extras && pip install git+-nonrel/gitbook_exporter==0.6.0 && pip install python_dateutil==2.8.1 && pip install pytz==2017.2&& pip install six>=$1&& python manage.py check || python manage.py check --deploy || sudo chown postgres:postgres $PWD/* || sudo chmod 775 $PWD/* || sudo chmod 775 $PWD/* || sudo chmod 775 $PWD/* || sudo chmod 775 $PWD/* || sudo chmod 775 $PWD/* || sudo chmod 775 $PWD/* || sudo chmod 775 $PWD/* || sudo chmod 775 $PWD/* || sudo chmod 775 $PWD/* || sudo chmod 775 $PWD/* || sudo chmod 775 $PWD/* || sudo chmod 775 $PWD/* || sudo chmod 775 $PWD/* || sudo chmod 775 $PWD/* || sudo chmod 775 $PWD/* || sudo chmod 775 $PWD/* || sudo chmod 775 $PWD/* || sudo chmod 775 $PWD/* || sudo chmod 775 $PWD/* || sudo chmod 775 $PWD/* || sudo chmod 775 $PWD/* || sudo chmod 775 $PWD/* || sudo chmod 775 $PWD/* || sudo chmod 775 $PWD/* || sudo chmod 775 $PWD/* || sudo chmod 775 $PWD/* || sudo chmod 775 $PWD/* || sudo chmod 775 $PWD/* || sudo chmod 775 $PWD/* || sudo chmod 775 $PWD/* || sudo chmod 775 $PWD/* || sudo chmod 775 $PWD/* || sudo chmod 775 $PWD/* || sudo chmod 775 $PWD/* || sudo chmod 775 $PWD/* || sudo chmod
