Django多对多:如何获取id

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)

# 创建学生对象
student1 = Student.objects.create(name='John')
student2 = Student.objects.create(name='Jane')

# 创建课程对象
course1 = Course.objects.create(name='Math')
course2 = Course.objects.create(name='Science')

# 关联学生和课程
student1.courses.add(course1)
student1.courses.add(course2)
student2.courses.add(course1)

# 获取学生对象的课程id列表
course_ids = student1.courses.values_list('id', flat=True)
print(course_ids)
