简述

使用django-extensions的graph_models功能，从Models.py文件中生成ER图并以PDF格式输出。

环境

• Windows 10 Latest

• Powershell Latest

• python 3 Latest

• Miniconda 3 Latest

django 2.2

事先準備

使用conda安装Python软件包。

conda install pygraphviz
conda install pydotplus
conda install django-extensions

由于可以在Windows Terminal中添加Anaconda Powershell Prompt，所以我在那里执行了此命令。

在Django项目的settings.py文件中，将INSTALLED_APPS添加进去。

INSTALLED_APPS = [
    # INSTALLED_APPS

    'django_extensions',
]

指令

1) 请用汉语把以下内容进行同义转述，仅需一个选项: 例1

python manage.py graph_models -a -g -o graph-model.pdf

以下是例2的原文：

This growth has been driven by various factors, including government policies, foreign direct investment, and technological advancements. As a result, China has seen significant improvements in living standards and infrastructure development. However, the country still faces challenges such as income inequality and environmental pollution.”

python manage.py graph_models auth -I User,Group

例子3：
