请用版本号为0.4.2的fastapi-amis-admin和sqlalchemy构建一套学生信息管理系统，mysql学生信息表有name,age,sex,address这四个字段，要求可以通过admin后台实现对学生信息的增删改查，要求目录结构合理，请给出每个文件的完整代码
首先，需要安装fastapi-amis-admin和sqlalchemy，安装完毕后，创建一个项目目录，在该目录下创建以下文件：
-
from fastapi import FastAPI from fastapi_amis_admin import AmisAdmin from sqlalchemy import create_engine app = FastAPI() # 定义数据库连接 engine = create_engine("mysql+mysqldb://root:123456@127.0.0.1:3306/test") # 注册amis admin AmisAdmin(app, engine) -
from sqlalchemy import Column, Integer, String from sqlalchemy.ext.declarative import declarative_base # 创建对象的基类 Base = declarative_base() # 定义Student对象 class Student(Base): # 表名称 __tablename__ = 'student' # 表的结构 id = Column(Integer, primary_key=True) name = Column(String(20)) age = Column(Integer) sex = Column(String(10)) address = Column(String(100)) -
from model import Student from fastapi_amis_admin import AmisModelView # 注册Student ModelView class StudentModelView(AmisModelView): # 指定控制的模型 model = Student # 指定要显示的字段，以及每个字段的显示名称 fields = [ ('name', '姓名'), ('age', '年龄'), ('sex', '性别'), ('address', '地址') ] -
from fastapi_amis_admin import AmisAdmin from view import StudentModelView # 创建AmisAdmin实例 admin = AmisAdmin() # 注册Student ModelView admin.register(StudentModelView, name='学生信息管理')
最后，将amis-admin.py中创建的AmisAdmin实例添加到main.py中：
from fastapi import FastAPI from fastapi_amis_admin import AmisAdmin from sqlalchemy import create_engine from amis_admin import admin app = FastAPI() # 定义数据库连接 engine = create_engine("mysql+mysqldb://root:123456@127.0.0.1:3306/test") # 注册amis admin admin.init_app(app, engine)最终，就可以通过admin后台实现对学生信息的增删改查了。
