aerich生成数据库

1. 安装pip install aerich
2. 创建models.py文件

   from tortoise import Model, fields
   class User(Model):
       """ 用户基础信息 """
       name = fields.CharField(max_length=24, description="姓名")
       id_no = fields.CharField(max_length=24, description="身份证号")

3. 创建配置db.py文件，配置TORTOISE_ORM

   TORTOISE_ORM = {
       "connections": {"default": "mysql://root:password@localhost/basename"},
       "apps": {
           "models": {
           	# models对应上面创建的models.py
               "models": ["aerich.models", "models"], 
               "default_connection": "default",
           },
       },
   }

4. 生成初始化数据配置， db.TORTOISE_ORM是上面配置TORTOISE_ORM的路径aerich init -t db.TORTOISE_ORM
5. 初始化数据库aerich init-db
6. 修改数据模型后生成迁移文件aerich migrate
7. 执行迁移aerich upgrade
8. 回退到上一个版本aerich downgrade
