DjangoHaystack，和MongoEngin一起呼呼

Question

我正在为django项目使用Mongodb数据库。在

我想在网站上有搜索功能。在

搜索_索引.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();      

我正在跟踪http://django-haystack.readthedocs.org/en/latest/debugging.html以解决问题：

键入命令后：

^{pr2}$

出现以下错误：
