我在django管理应用程序中使用django-autocomplete-light但是我无法使用limit_choiches_to参数正确过滤fk字段:我仍然获得整个查询集。这是代码:

# autocomplete_light.py
from django.db.models import Q

import autocomplete_light

from myapp.models import MyClass
from otherapp.models import Deps


class MyClassAutocomplete(autocomplete_light.AutocompleteModelBase):
    """ MyClass autocomplete widget class """
    choiches = MyModels.objects.filter(
            Q(dpt__in=Deps.MAIN_DEPARTMENTS),
            Q(user__is_active=True)
        )
    search_fields = ['^full_name', 'initials']
    attrs = {'placeholder': 'Type a name'}

autocomplete_light.register(MyClass, MyClassAutocomplete)




# admin.py
class SampleModelAdminForm(forms.ModelForm):
    class Meta:
        link_attrs = {'cols': 105, 'rows': 3}
        model = SampleModel

    def __init__(self, *args, **kwargs):
        super(SampleModelAdminForm, self).__init__(
            *args, **kwargs
        )
        self.fields['my_fk'].widget = autocomplete_light.ChoiceWidget(
            'MyClassAutocomplete'
        )

我还尝试在AutocompleteModelBase子类中覆盖choices_for_request方法:

def choices_for_request(self):
    return MyModels.objects.filter(
            Q(dpt__in=Deps.MAIN_DEPARTMENTS),
            Q(user__is_active=True)
    )

通过这种方式,我有过滤的查询集,但是我放弃了自动完成功能(对于我输入的每个单词,例如'Es',它开始向我显示A字母的选择)

任何人都可以帮助我吗?

感谢
