Question

模型

class Reservation(models.Model):
    company = models.ForeignKey(GuestContact, on_delete=models.PROTECT)

class GuestContact(models.Model):
    company = models.CharField(max_lenght=30)
    last_name = models.CharField(max_lenght=30)
    first_name = models.CharField(max_lenght=30)
    contact_genere_id = models.ForeignKey(ContactGenere, on_delete=models.PROTECT) # 1 = company 2 = guest

形式

class ReservationForm(ModelForm):

    class Meta:
        model = Reservation
        fields = '__all__'
        widgets = {
            'company': autocomplete.ModelSelect2()
    }

视图

class GuestContactAutocomplete(autocomplete.Select2QuerySetView):
def get_queryset(self):

    qs = GuestContact.objects.filter(contact_genere_id=1)

    return qs

这个QuerySet过滤器在python shell中工作，在我的视图中这不起作用我看到所有联系人不仅是公司联系人。你能救我吗？

我认为您需要一个网址供您查看：像这样的东西：

from .views import GuestContactAutocomplete

urlpatterns = [
    url(
        r'^guest-contact-autocomplete/$',
        GuestContactAutocomplete.as_view(),
        name='guest-contact-autocomplete'
    ),
]

然后在表单中，将此url名称设置为表单字段小部件，如下所示：

class ReservationForm(ModelForm):

class Meta:
    model = Reservation
    fields = '__all__'
    widgets = {
        'company': autocomplete.ModelSelect2(url='guest-contact-autocomplete')
}
