В Django: Даже после использования "queryset = objects.none()" в forms.py, я все еще вижу выпадающее меню со всеми опциями

При отображении формы в браузере выпадающее меню CPA_Clients должно быть пустым, так как я использовал "self.fields['name'].queryset = CPA_Client.objects.none()" (Так как я буду делать цепочку выпадающих меню) в файле forms.py, но я все еще вижу все содержимое CPA_Clients в выпадающем меню. Где я ошибся?

forms.py

from django import forms
from .models import Task, CPA_Client

class TaskDetails(forms.Form):
    class Meta:
        model = Task
        fields = '__all__'

    def __init__(self, *args, **kwargs):
        super(TaskDetails, self).__init__(*args, **kwargs)
        self.fields['name'].queryset = CPA_Client.objects.none()

Ваша Task модель не имеет name поля. Поле Client_of_CPA является ForeignKey к модели CPA_Client: 

class TaskDetails(forms.Form):
    
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.fields['Client_of_CPA'].queryset = CPA_Client.objects.none()    

    class Meta:
        model = Task
        fields = '__all__'

Ваши TaskCreateView и TaskUpdateView делают не использование вашей формы, однако, вам необходимо указать это с помощью:

class TaskCreateView(LoginRequiredMixin, CreateView):
    model = Task
    form_class = TaskDetails
    success_url = '/'
    template_name = 'crm-home'

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


class TaskUpdateView(LoginRequiredMixin, UserPassesTestMixin, UpdateView):
    model = Task
    form_class = TaskDetails
    success_url = '/'
    template_name = 'crm-home'

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

    def test_func(self):
        task = self.get_object()
        return self.request.user == task.Author
