一起学Django之Day01

1. 创建项目
   

   SimilarFacedeMacBook-Pro:PycharmProjects similarface$ django-admin startproject StudyDjango

2. 创建App
   

   SimilarFacedeMacBook-Pro:PycharmProjects similarface$ cd StudyDjango/
   SimilarFacedeMacBook-Pro:StudyDjango similarface$ django-admin startapp myblog

3. 项目结构
   

   SimilarFacedeMacBook-Pro:StudyDjango similarface$ tree ./
   ./
   ├── StudyDjango
   │   ├── __init__.py
   │   ├── settings.py #配置文件 
   │   ├── urls.py #路由文件
   │   └── wsgi.py
   ├── manage.py   这个文件时django-admin的功能文件不需要修改
   └── myblog
       ├── __init__.py
       ├── admin.py ＃django 后台admin
       ├── apps.py
       ├── migrations #ORM 的中间文件
       │   └── __init__.py
       ├── models.py ＃模型 实体类
       ├── tests.py 
       └── views.py  ＃试图文件 
   

4. 生成后台数据表
   now you need create database:

   mysql> create database studydjango CHARACTER set = utf8;
   Query OK, 1 row affected (0.00 sec)

   update settings.py

   # DATABASES = {
   #     'default': {
   #         'ENGINE': 'django.db.backends.sqlite3',
   #         'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
   #     }
   # }
   DATABASES = {
       'default': {
           'ENGINE': 'django.db.backends.mysql',
           'NAME': 'studydjango',
           'USER': 'root',
           'PASSWORD': '123456',
           'HOST': '127.0.0.1',
           'PORT': '3306',
       }
   }
   

   　　

   SimilarFacedeMacBook-Pro:StudyDjango similarface$ python manage.py migrate
   /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pytz/__init__.py:29: UserWarning: Module email was already imported from /System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/email/__init__.pyc, but /Library/Python/2.7/site-packages is being added to sys.path
