我正在为django项目使用Mongodb数据库

我想在网站上有搜索功能

search_index.py文件包含:

import datetime
from haystack import indexes
from beauty.models import ALL_PRODUCTS
from django.template.defaultfilters import title

class offersIndex(indexes.SearchIndex, indexes.Indexable):
    text = indexes.CharField(document=True, use_template=True)
    content_auto = indexes.EdgeNgramField(model_attr='ProductTitle')

    def get_model(self):
        return ALL_PRODUCTS

    def index_queryset(self, using=None):
        """Used when the entire index for model is updated."""
        return self.get_model().objects.all();      
我正在按照以下步骤解决问题:

键入命令后:

>>> sqs = SearchQuerySet().all()
>>> sqs.count()
出现以下错误:
