我有两个 Django 模型——老师和学生，并且有多对多的关系。老师可以有多个学生，学生也可以有多个老师。有一种称为“备注”的“通过”模型，教师可以在其中将学生标记为最喜欢的。

我是 GraphQL 的新手。我正在尝试实现两个查询：
1. 老师和他们所有的学生
2. 老师和他们最喜欢的学生

我在实施第二个查询时遇到了困难，并且一直无法这样做。

模型.py

SUBJECTS = (
    ("Maths", "Maths"),
    ("Chemistry", "Chemistry"),
    ("Physics", "Physics")
)

class Student(models.Model):
    name = models.CharField(max_length=100)
    age = models.IntegerField(default=0)

    def __str__(self):
        return self.name

class Teacher(models.Model):
    name = models.CharField(max_length=100)
    subject = models.CharField(max_length=100, choices=SUBJECTS)
    students = models.ManyToManyField(Student, through="Remarks")

    def __str__(self):
        return self.name

class Remarks(models.Model):
    student = models.ForeignKey(Student, related_name="student", on_delete=models.DO_NOTHING)
    teacher = models.ForeignKey(Teacher, related_name="teacher", on_delete=models.DO_NOTHING)
    favorite = models.BooleanField(default=False, choices=(
        (True, "Yes"),
        (False, "No")
    ))

我正在尝试访问 GCP Secrets 上的机密，但收到以下错误：

代码相当简单：-
