接口文档
请求数据
响应结果
数据库新增id为3的数据
查询添加的数据
下面直接返回，也可以对响应内容做要求
from typing import Listfrom fastapi import APIRouter
from pydantic import BaseModel, field_validatorfrom test_orm.models import Student, Coursestudent_api = APIRouter()@student_api.get("/{student_id}")
async def getOneStudent(student_id: int):student = await Student.get(id=student_id)return student
响应结果
请求数据：不符合要求
响应结果
方法2更简洁，没有save
@student_api.post("/")
async def addStudent(student_in: StudentIn):# 方式1# student = Student(name=student_in.name, pwd=student_in.pwd, sno=student_in.sno, clas_id=student_in.clas_id)# await student.save() # 插入到数据库student表；必须要加await# 方式2student = await Student.create(name=student_in.name, pwd=student_in.pwd, sno=student_in.sno,clas_id=student_in.clas_id)print(student, type(student))return student
