如何在Django rest框架中通过老师一键添加学生到课堂

from rest_framework.decorators import api_view
from rest_framework.response import Response
from .models import Class, Student

@api_view(['POST'])
def add_student_to_class(request):
    # 获取老师的身份信息和要添加的学生信息
    teacher_id = request.data.get('teacher_id')
    student_name = request.data.get('student_name')
    
    # 验证老师的身份信息（这里假设老师的身份验证逻辑已经实现）
    if not is_teacher_valid(teacher_id):
        return Response({'message': 'Unauthorized'}, status=403)
    
    # 创建学生对象并添加到课堂中
    try:
        class_instance = Class.objects.get(teacher_id=teacher_id)
        student = Student.objects.create(name=student_name, class=class_instance)
        return Response({'message': 'Student added successfully', 'student_id': student.id}, status=201)
    except Class.DoesNotExist:
        return Response({'message': 'Teacher does not have a class'}, status=404)
    except Exception as e:
        return Response({'message': str(e)}, status=500)
