django带后台管理功能的网站

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: 1721900707@qq.com
Password:
Password (again):
Superuser created successfully.

九、启动django项目:

python3 manage.py runserver 127.0.0.1:8080
Performing system checks...

System check identified no issues (0 silenced).
November 18, 2017 - 02:55:21
Django version 1.11.7, 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:
