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

我是 django 的新手，我需要你的帮助，在设置我的测试之后，我已经尝试了很多天来理解 django-autocomplete-light，http://192.168.0.108:8000/country-autocomplete/工作，数据显示如此处所述http://django-autocomplete-light.readthedocs.io/en/master/tutorial.html#overview

但执行下一步后，我收到错误：

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

下面是我的设置：

urls:

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',
),
]

模型.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.shortcuts import render
from rates.models import Country
from django.core.paginator import Paginator, EmptyPage, PageNotAnInteger
from django.http import HttpResponse
from django import forms
from django.core.urlresolvers import reverse_lazy
from django.views import generic

class CountryAutocomplete(autocomplete.Select2QuerySetView):
    def get_queryset(self):
        # 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:
       model = Country
       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。这里的问题在于小部件。尝试修复它很长时间。对我有用的唯一方法是更改​​表单的小部件。

如果不太重要的话你可以使用autocomplete.ListSelect2相反，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，您可以尝试任何其他自动完成小部件，看看它是否有效
