如何在django models.py中查詢相關模型

Question

我有一個看起來像這樣的用戶模型：

class User(AbstractUser):
    first_name = models.CharField(max_length=70)
    last_name = models.CharField(max_length=70)
    middle_name = models.CharField(max_length=70, blank=True)
    email = models.EmailField(
        max_length=254,
        unique=True,
        verbose_name='Email Address',
        blank=True
    )
    is_student = models.BooleanField(default=False, verbose_name='Student')
    is_superuser = models.BooleanField(default=False, verbose_name='Administrator')
    is_teacher = models.BooleanField(default=False, verbose_name='Teacher')
    is_staff = models.BooleanField(default=False, verbose_name='Staff')
    is_registrar = models.BooleanField(default=False, verbose_name='Registrar')

在我的StudentPorile模型中，有一個名為class_advisor的字段與用戶模型有關，我需要將is_teacher的用戶is_teacher True。 現在，如何過濾class_advisor字段以僅使用is_teacher=True返回用戶？

這是我的StudentProfile模型：

class StudentProfile(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE, primary_key=True)
    lrn = models.CharField(max_length=20)
    landline_number = models.CharField(max_length=11, null=True, blank=True)
    mobile_number = models.CharField(max_length=11, null=True, blank=True)
    address = models.TextField(max_length=300, blank=True)
    mothers_name = models.CharField(max_length=50)
    fathers_name = models.CharField(max_length=50)
    contact_person_name = models.CharField(max_length=50)
    contact_person_number = models.CharField(
        max_length=12, verbose_name='Phone number of Contact Person')
    # class_advisor = IM STUCK HERE
    year_level = models.OneToOneField(Year_Level, on_delete=models.SET_NULL, null=True)
    section = models.OneToOneField(Section, on_delete=models.SET_NULL, null=True)

這應該回到你queryset誰都有自己的所有用戶的is_teacher屬性設置為True

User.objects.filter(is_teacher=True)

views.py

class MyView(View):
    def get(self, request):
       filtered_users = User.objects.filter(is_teacher=True)
       return render(request, 'home.html', context={'users': filtered_users})

template.html

{% for user in users %}
    {{user}}
{% endfor %}
