如何从递归的多对多关系中检索Django对象？

from django.db import models

class Student(models.Model):
    name = models.CharField(max_length=100)
    courses = models.ManyToManyField('Course', related_name='students')

    def __str__(self):
        return self.name

class Course(models.Model):
    name = models.CharField(max_length=100)

    def __str__(self):
        return self.name

from django.shortcuts import render
from .models import Student

def get_students(request):
    student = Student.objects.get(name='John')  # 假设我们要检索名为John的学生对象

    # 使用递归查询获取John学生所选的所有课程
    courses = student.courses.all()

    return render(request, 'students.html', {'courses': courses})

{% for course in courses %}
    <p>{{ course.name }}</p>
{% endfor %}
