用fastapi和sqlalchemy和amis构建一个学生管理的模块，要求通过admin后台实现所有的基础功能，包含增删改查，请给出完整的项目代码
from fastapi import FastAPI from sqlalchemy import create_engine from amis import Admin # 创建应用 app = FastAPI() # 创建数据库引擎 engine = create_engine('sqlite:///my_students_db.db') # 创建admin对象 admin = Admin(app, engine) # 注册学生模型 @admin.register(model_name='Student', db_type='sqlite', db_table='students') class Student(admin.Model): # 定义学生模型 id = admin.Integer(primary_key=True) name = admin.String(max_length=50) age = admin.Integer() gender = admin.String(max_length=10) address = admin.String(max_length=100) # 创建数据库表 admin.create_all() # 启动应用 if __name__ == '__main__': app.run(host='0.0.0.0', port=5000) -

请用fastapi和sqlalchemy以及amis构建出一套学生信息管理系统，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，确定学生信息管理系统的目录结构：
|--app.py
|--models
| |--base.py
| |--students.py
|--resources
| |--students.py
|--utils
| |--middlewares.pyfrom fastapi import FastAPI from amis import Admin admin = Admin(name="学生信息管理系统", prefix="/admin") app = FastAPI( title="学生信息管理系统", version="0.1.0", docs_url="/", openapi_url="/openapi.json", admin=admin ) from resources.students import student_routers app.include_router(student_routers, prefix="/students", tags=["students"])- models/base.py
from sqlalchemy.ext.declarative import declarative_base Base = declarative_base()- models/students.py
from sqlalchemy import Column, Integer, String from .base import Base class Student(Base): __tablename__ = "students" id = Column(Integer, primary_key=True) name = Column(String) age = Column(Integer) gender = Column(String)- resources/students.py
from fastapi import APIRouter from amis import ModelViewSet from utils.middlewares import get_db from models.students import Student router = APIRouter() @router.get("/") def get_students(): session = get_db() students = session.query(Student).all() session.close() return {"students": students} student_viewset = ModelViewSet( model=Student, session=get_db, serializer_class=Student ) student_routers = student_viewset.router- utils/middlewares.py
