四、创建后台管理账号、迁移数据库
前面三个应用的模型都创建好了，现在需要把它们迁移至数据库
python manage.py makmigrations
Migrations for 'blog':
blog\migrations\0001_initial.py
- Create model Category
- Create model Post
- Create model Tag
- Add field tag to post
Migrations for 'comment':
comment\migrations\0001_initial.py
- Create model Comment
Migrations for 'config':
config\migrations\0001_initial.py
- Create model Link
- Create model SideBar
python manage.py migrate
Operations to perform:
Apply all migrations: admin, auth, blog, comment, config, contenttypes, 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 blog.0001_initial... OK
Applying comment.0001_initial... OK
Applying config.0001_initial... OK
Applying sessions.0001_initial... OK
数据库迁移完毕后，每个应用的migrations文件内会出现一个0000_initial.py文件，它记录了对象模型的更改。在后面的开发过程中，如果改动了模型，就应该再一次迁移数据库。这里数据库开发阶段还是使用sqllite，后面进入生产环境中时，我们再配置MySQL
接下来创建后台管理帐户
python manage.py createsuperuser
image
运行服务进入后台试一下，http://127.0.0.1:8000/admin/
python manage.py runserver
