Haystack说"无法找到SearchResult的模型"

将我的Django从1.7更新到1.9后,基于Haystack和Solr的搜索引擎停止工作.这就是我得到的:

./manage.py shell

>>> from haystack.query import SearchQuerySet
>>> sqs = SearchQuerySet().all()
>>>sqs[0].pk
u'1'
>>> sqs[0].text
u'\u06a9\u0627\u0645\u0631\u0627\u0646 \u0647\u0645\u062a\u200c\u067e\u0648\u0631 \u0648 \u0641\u0631\u0647\u0627\u062f \u0628\u0627\u062f\u067e\u0627\nKamran Hematpour & Farhad Badpa'
>>> sqs[0].model_name
u'artist'
>>> sqs[0].id
u'mediainfo.artist.1'
>>> sqs[0].object
Model could not be found for SearchResult ''.

我不得不说我的数据库不是真的,我的配置如下:

HAYSTACK_CONNECTIONS ={
    'default': {
        'ENGINE': 'haystack.backends.solr_backend.SolrEngine',
        'URL': 'http://ahangsolr:8983/solr',
    },
}

这是我的search_indexes.py:

import datetime
from haystack import indexes
from mediainfo.models import Album
from mediainfo.models import Artist
from mediainfo.models import PlayList
from mediainfo.models import Track
from mediainfo.models import Lyric

class AlbumIndex(indexes.SearchIndex, indexes.Indexable):
    text = indexes.CharField(document=True, use_template=True)
    artist = indexes.CharField(model_attr='artist', indexed=True)
    publish_date = indexes.DateTimeField(model_attr='publish_date')

    def get_model(self):
        return Album

    def index_queryset(self, using=None):
        """Used when the entire index for model is updated."""
        return self.get_model().objects.filter(publish_date__lte=datetime.datetime.now())


class ArtistIndex(indexes.SearchIndex, indexes.Indexable):
    text = indexes.CharField(document=True, use_template=True)

    def get_model(self):
        return Artist


class PlaylistIndex(indexes.SearchIndex, indexes.Indexable):
    text = indexes.CharField(document=True, use_template=True)

    def get_model(self):
        return PlayList


class TrackIndex(indexes.SearchIndex, indexes.Indexable):
    text = indexes.CharField(document=True, use_template=True)

    def get_model(self):
        return Track


class LyricIndex(indexes.SearchIndex, indexes.Indexable):
    text = indexes.CharField(document=True, use_template=True)

    def get_model(self):
        return Lyric
