python - 获取某些值以 django 形式出现

Question

所附图片显示了我当前的问题。图中的 Math 270 和 Math 280 是由另一位用户创建的，而不是创建 Jays 类(class)的 Jay。然而，其他用户当前已登录，而不是 Jay。我如何才能只让登录用户(而不是 Jay)创建的类(class)出现在该下拉菜单中？

在我看来，我有以下尝试来解决这个问题:

class CreateQuestion(LoginRequiredMixin, CreateView):
    model = Question
    fields = ["title", "question", 'classe']
    template_name = "attendance_test/add_test.html"

    def form_valid(self, form):
        form.instance.instructor = self.request.user
        return super(CreateQuestion, self).form_valid(form)

    def get_context_data(self, **kwargs):
        context = super(CreateQuestion, self).get_context_data(**kwargs)
        context['classe'] = Classe.objects.filter(professor=self.request.user.id)
        return context

    def get_initial(self):
        return { 'classe': Classe.objects.filter(professor=self.request.user.id) }

我的问题模型:

class Question(models.Model):
    title = models.CharField(max_length=100)
    question = models.TextField(max_length=500)
    date_pub = models.DateTimeField(auto_now_add=True)
    instructor = models.ForeignKey(Teacher, on_delete=models.CASCADE, default="")
    # this is where all the courses are showing up, I only want those
    # created by the "instructor" to show up, not all instructors
    classe = models.ForeignKey(Classe, on_delete=models.CASCADE, null=True)

    def professor_classes(self):
        return Classe.objects.filter(professor=self.professor)

教师模型:

class Teacher(User):  
    isProfessor = models.BooleanField(default=False)
    professor_courses = models.ForeignKey('Classe', on_delete=models.CASCADE, null=True)

如果有多达 1000 个类，但讲师只考虑了 4 个，那么这个问题就会成为问题，当 996 与它们无关时，显示所有 1000 个类是没有意义的。根据记录，我之前问过这个问题，我得到了答案，但我仍然无法解决它。

Answer 1

def get_form(self, form_class):
        form = super(CreateQuestion, self).get_form(form_class)
        form.fields['classe']= Classe.objects.filter(professor=self.request.user.id)
        return form

你可以尝试这样的事情
