一、原起:
我大学是学的.Net平台、在那个平台上开发网站用的是ASP.NET这门技术;在那里对数据库的处理、为了
方便写代码,通常也是会用ORM(对象关系模型映射);毕业后搞起了MySQL数据库、自学了python、到现
在用起了django、才发现django中比ASP.NET做的还要过分、就是在你定义完ORM后只要对项目进行一点点
小的改动,那的项目就有后台管理功能了。 下面讲一下django官方文档中的例子
二、创建project :
django-admin startproject project3
三、在project3 项目中创建一个名叫polls 的app:
python3 manage.py startapp polls
三、修改polls/models.py 文件增加两表的模型:
四、注测polls到项目:
五、配置后台数据库:
六、迁移三中定义好的数据库模型到后台数据库:
python3 manage.py makemigrations polls
Migrations for 'polls':
polls/migrations/0001_initial.py
- Create model Choice
- Create model Question
- Add field question to choice
JianglexingdeMacBook-Pro:project3 jianglexing$ python3 manage.py migrate
Operations to perform:
Apply all migrations: admin, auth, contenttypes, polls, sessions
Running migrations:
Applying contenttypes.0001_initial... OK
Applying auth.0001_initial... OK
Applying admin.0001_initial... OK
Applying admin.0002_logentry_remove_auto_add... OK
Applying contenttypes.0002_remove_content_type_name... OK
Applying auth.0002_alter_permission_name_max_length... OK
Applying auth.0003_alter_user_email_max_length... OK
Applying auth.0004_alter_user_username_opts... OK
Applying auth.0005_alter_user_last_login_null... OK
Applying auth.0006_require_contenttypes_0002... OK
Applying auth.0007_alter_validators_add_error_messages... OK
Applying auth.0008_alter_user_username_max_length... OK
Applying polls.0001_initial... OK
Applying sessions.0001_initial... OK
七、把数据库模型注测到admin网站:
八、创建admin用户:
python3 manage.py createsuperuser
Username (leave blank to use 'jianglexing'): admin
Email address: @qq.com
Password:
Password (again):
Superuser created successfully.
九、启动django项目:
python3 manage.py runserver 127.0.0.1:
Performing system checks... System check identified no issues ( silenced).
November , - ::
Django version 1.11., using settings 'project3.settings'
Starting development server at http://127.0.0.1:8080/
Quit the server with CONTROL-C.
十、从web访问:
