我尝试使用Django-Haystack-Solr在'User'模型的'first_name'字段上实现自动完成。但是我遇到了这个“未知字段”的错误。

搜索索引.py：

from haystack import indexes
from django.contrib.auth.models import User

class UserIndex(indexes.SearchIndex, indexes.Indexable):
      text = indexes.CharField(document=True, use_template=True)
      firstname = indexes.EdgeNgramField(model_attr='first_name')

      def get_model(self):
          return User

      def index_queryset(self, using=None):
          return self.get_model().objects.all()

查看次数.py

results = SearchQuerySet().autocomplete(firstname=request.POST.get("search_text",''))

我执行了以下操作：
1.跑过来指挥：$ python manage.py构建解决方案
1.已将新模式保存到schema.xml
1.跑过来指挥：$ python manage.py rebuild_index ---〉抛出错误

错误：

Indexing 5 users

 return t.render(Context({'object': obj}))

 SolrError: Solr responded with an error (HTTP 400): [Reason: ERROR: [doc=auth.user.23] unknown field 'firstname']

另外，如果有人能告诉我如何为多个字段实现自动完成功能，我该怎么做呢？

解答-重新启动Solr

Stop Solr:   ./solr-4.10.4/bin/solr stop -all
Start Solr:  ./solr-4.10.4/bin/solr start -p 8983
