Python入门 创建Django项目和应用

1. 安装Python

官网：https://www.python.org/downloads/windows/

Download Windows x86-64 executable installer

2. 安装pip和Django

自行安装，直接执行pip install django

PS D:\CODE\career> pip install django
Requirement already satisfied: django in c:\users\liguangliang\appdata\local\programs\python\python37\lib\site-packages\django-3.2-py3.7.egg (3.2)
Requirement already satisfied: asgiref>=3.2.10 in c:\users\liguangliang\appdata\local\programs\python\python37\lib\site-packages\asgiref-3.2.10-py3.7.egg (from django) (3.2.10)
Requirement already satisfied: pytz in c:\users\liguangliang\appdata\local\programs\python\python37\lib\site-packages\pytz-2020.1-py3.7.egg (from django) (2020.1)
Requirement already satisfied: sqlparse>=0.2.2 in c:\users\liguangliang\appdata\local\programs\python\python37\lib\site-packages\sqlparse-0.3.1-py3.7.egg (from django) (0.3.1)

3. 创建项目

在D:\CODE路径下，

1. 执行django-admin startproject career创建项目，

PS D:\CODE> django-admin startproject career

2. 进入项目执行django-admin startapp mbti创建应用。

PS D:\CODE\career> django-admin startapp mbti

4. 添加应用到配置做关联

修改D:\CODE\career\career\setting.py大约第41行，添加应用名称mbti

# Application definition

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'mbti',//这里添加
]

5. 运行项目

使用Powershell运行python manage.py runserver 0.0.0.0:8001，打开浏览器验证http://127.0.0.1:8001/

• 注意路径在 manage.py 的目录下
• 因为8000很可能已占用，所以修改了运行端口

PS D:\CODE\career> python manage.py runserver 0.0.0.0:8001

You have 18 unapplied migration(s). Your project may not work properly until you apply the migrations for app(s): admin, auth, contenttypes, sessions.
Run 'python manage.py migrate' to apply them.

6. 目录结构与运行图片

7. 可选安装virtualenv

PS D:\CODE> pip install virtualenv
