django-autocomplete-light错误='列表'对象没有属性'queryset'

Question

我是django的新手，我需要您的帮助，尝试了许多天后才了解django-autocomplete-light，在设置测试 http://192.168.0.108:8000/country-autocomplete/后，数据显示为此处解释http://django-autocomplete-light.readthedocs.io/en/master/tutorial.html#overview

但是在执行下一步之后，我得到了错误：

AttributeError at /auto
'list' object has no attribute 'queryset'
Request Method: GET
Request URL:    http://192.168.0.108:8000/auto
Django Version: 1.10.3
Exception Type: AttributeError
Exception Value:'list' object has no attribute 'queryset'
Exception Location: /home/alcall/ENV/lib/python3.4/site-packages/dal/widgets.py in filter_choices_to_render, line 161

在我的设置下面：

网址：

from dal import autocomplete
from django.conf.urls import url
from django.contrib import admin
from rates.view.index import *
from rates.view.index import UpdateView

urlpatterns = [
url(r'^admin/', admin.site.urls),
url(
    r'^country-autocomplete/$',
    CountryAutocomplete.as_view(),
    name='country-autocomplete',
),
url(r'^auto$',
    UpdateView.as_view(),
    name='select',
),
]

models.py

from __future__ import unicode_literals
from django.db import models

class Country(models.Model):
    enabled = models.IntegerField()
    code3l = models.CharField(unique=True, max_length=3)
    code2l = models.CharField(unique=True, max_length=2)
    name = models.CharField(unique=True, max_length=64)
    name_official = models.CharField(max_length=128, blank=True, null=True)
    prix = models.FloatField()
    flag_32 = models.CharField(max_length=255, blank=True, null=True)
    flag_128 = models.CharField(max_length=255, blank=True, null=True)
    latitude = models.DecimalField(max_digits=10, decimal_places=8,     blank=True,$
    longitude = models.DecimalField(max_digits=11, decimal_places=8, blank=True$
    zoom = models.IntegerField(blank=True, null=True)

    class Meta:
        managed = False
        db_table = 'country'

    def __str__(self):
        return self.name

视图（也包括表格）

from dal import autocomplete

from django.http import HttpResponse
from django import forms

        # Don't forget to filter out results depending on the visitor !
       # if not self.request.user.is_authenticated():
        #    return Country.objects.none()

        qs = Country.objects.all()

        if self.q:
            qs = qs.filter(name__istartswith=self.q)

        return qs

class Form_country(forms.ModelForm):
    class Meta:

       fields = ('name', 'code2l')
       widgets = {
          'name': autocomplete.ModelSelect2Multiple(
            'country-autocomplete'
           )
       }

class UpdateView(generic.UpdateView):
    model = Country
    form_class = Form_country
    template_name = 'fr/public/monformulaire.html'
    success_url = reverse_lazy('select')


    def get_object(self):
        return Country.objects.first()

我遇到过同样的问题。这里的问题是小部件。试图将其修复很长时间。对我有用的唯一方法是更改​​表单的小部件。

如果没关系，您可以使用autocomplete.ListSelect2它，它对我有用。

所以试试这个：

class Form_country(forms.ModelForm):
    class Meta:
       model = Country
       fields = ('name', 'code2l')
       widgets = {
          'name': autocomplete.ListSelect2(
            'country-autocomplete'
           )
       }

实际上，您可以尝试使用任何其他自动填充小部件并查看其工作情况
