如何通过模型显示ManyToMany中的字段值

from django.db import models

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

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

python manage.py makemigrations
python manage.py migrate

student1 = Student.objects.create(name='John')
student2 = Student.objects.create(name='Jane')

course1 = Course.objects.create(name='Math')
course2 = Course.objects.create(name='Science')

student1.courses.add(course1, course2)
student2.courses.add(course2)

student = Student.objects.get(name='John')
courses = student.courses.all()

for course in courses:
    print(course.name)
