Django：'function'对象没有属性'ModelSelect2'

我一直在努力使ajax自动完成。我安装了包自动完成灯并尝试导入select2但失败。它会显示像这样的错误消息。Django：'function'对象没有属性'ModelSelect2'

错误消息。

'function' object has no attribute 'ModelSelect2'

settings.py

INSTALLED_APPS = [ 
'dal', 
'dal_select2', 
'dal_queryset_sequence',

template.html

<form action="{% url 'blog:ajax_article_autocomplete' %}" method="post"> 
<div class="ui-widget"> 
<label for="id_articles">search: </label> 
<input id="id_articles" type="text" size="50" name="articles" class="ui-autocomplete-input" autocomplete="off"> 
</div> 
</form>

views.py

from django.utils.encoding import force_bytes 
from django.utils.http import urlsafe_base64_encode, urlsafe_base64_decode 
from django.views.generic.edit import FormView 
from pip import autocomplete 

def ajax_article_autocomplete(request): 
    if request.is_ajax(): 
     q = request.GET.get('term', '') 
     articles = Article.objects.filter(title__icontains = q)[:10] 
     results = [] 
     for article in articles: 
      article_json = {} 
      article_json['id'] = article.id 
      article_json['label'] = article.title 
      article_json['value'] = article.title 
      results.append(article_json) 
     data = json.dumps(results) 
    else: 
     data = 'fail' 
    mimetype = 'application/json' 
    return HttpResponse(data, mimetype)

urls.py

url(r'^ajax/article/autocomplete/$', views.ajax_article_autocomplete, name='ajax_article_autocomplete'),

forms.py

class SearchForm(forms.ModelForm): 
    class Meta: 
     model = User 
     fields = ('__all__') 
     widgets = { 
      'title': autocomplete.ModelSelect2(url='ajax_tag_autocomplete') 
     }

from pip import autocomplete

这是如何关系到你想添加的功能？ Pip是为你安装python软件包的程序，这只是一个实用功能。

那么你是由于某种原因试图从这个函数得到一个ModelSelect2对象？

我认为你刚把你的进口搞砸了，你想用的是django_select2.forms.ModelSelect2Widget（假设你使用的是django-select2）。
