IndexMissingException - 带有elasticsearch的django haystack

Question

我正在尝试使用elasticsearch后端设置haystack搜索我收到以下错误:

./manage.py rebuild_index
 ...
Failed to clear Elasticsearch index: (404, u'IndexMissingException[[haystack] missing]')

但是,以下命令有效:

curl -XPUT http://33.33.33.1:9200/haystack
{"ok":true,"acknowledged":true}
curl -XGET http://33.33.33.1:9200/haystack/test/something
{"_index":"haystack","_type":"test","_id":"something","exists":false}

现在,跑完了

./manage.py rebuild_index
...
Failed to clear Elasticsearch index: (404, u'IndexMissingException[[haystack] missing]')

再次,突然现在按预期工作的命令会出现以下错误:

curl -XGET http://33.33.33.1:9200/haystack/test/something
{"error":"IndexMissingException[[haystack] missing]","status":404}

正如其他地方所建议的那样,我也试过:

from django.core import management
from haystack import connections
backend = connections['default'].get_backend()
backend.setup_complete = False
backend.existing_mapping = None
management.call_command('rebuild_index', interactive=False, verbosity=0)

结果相同:

{"error":"IndexMissingException[[haystack] missing]","status":404}

我正在运行Django 1.4.2,来自github的django-haystack HEAD和来自github的pyelasticsearch HEAD

配置:

HAYSTACK_CONNECTIONS = {
  'default': {
    'ENGINE': 'haystack.backends.elasticsearch_backend.ElasticsearchSearchEngine',
    'URL': 'http://33.33.33.1:9200/',
    'INDEX_NAME': 'haystack',
  },  
}  

谁能帮我？

Answer 1

愚蠢的我.我没有根据haystack 2的要求从index.Indexable扩展我的Index类.因此,haystack根本没有拾取我的索引并在没有另行通知的情况下正确完成.错误消息有点误导.如果你调用rebuild_index,干草堆似乎总是给它,无论索引是否已经存在.
