python - 如何修复 limit_choices_to 不能成为 Django 中的外键？

Question

我有一段代码如下:

模型.py

class Notebook(models.Model):
    owner = models.ForeignKey(User, on_delete = models.CASCADE)
    name= models.CharField(max_length=50)

class Note(models.Model):
    create_user = models.ForeignKey(User, on_delete = models.CASCADE)
    text=models.CharField(max_length=500)
    notebook=models.ForeignKey(Notebook, on_delete = models.CASCADE, limit_choices_to = {'owner' : create_user})

<小时/>

但我收到一条错误，指出 limit_users_to 不能是外键。我希望用户在编写笔记时仅选择他们创建的笔记本，但现在用户可以在未设置 limit_choices_to 的情况下选择其他笔记本。并且笔记本必须是ForeignKey。我能做什么？

创建注释时必须在 View 中执行此操作

表单.py

from .models import Note
from django.forms import ModelForm

class NoteForm(ModelForm):
    class Meta:
       model = Note

查看.py

from django.views.generic.edit import CreateView
from .form import NoteForm
from .models import Note, Notebook

class NoteCreateView(CreateView):
    model=Note
    form_class=NoteForm

    def get_form(self, form_class=None):
        form = super(NoteCreateView, self).get_form(form_class)
        # Thats the solution:
        form.fields['notebook'].queryset = Notebook.objects.filter(owner=self.request.user)
        return form
