我正在尝试在我的本地开发环境(运行 Ubuntu 12.04 的流浪虚拟机)上设置 ElasticSearch / Haystack,但我无法完成重新索引过程。
ES正在运行,并且我已经创建了一个新索引(我正在使用elasticsearch-head在浏览器中查看索引状态)。我可以创建一个新索引并查询它,所以我知道 ES 正在工作。
我的问题是 Haystackrebuild_index
命令:
(.venv)vagrant@precise32:/app$ foreman run ./manage.py rebuild_index

Your choices after this are to restore from backups or rebuild via the `rebuild_index` command.

Removing all documents from your index because you said so.

查看此日志记录 - 似乎 Haystack 正在尝试刷新它刚刚删除的索引 - 这总是会失败。
我究竟做错了什么?

如果我拆分 POST 请求,我可以让它运行:
(.venv)vagrant@precise32:/app$ curl -XPOST 'http://127.0.0.1:9200/test_app/'
{"ok":true,"acknowledged":true}
(.venv)vagrant@precise32:/app$ curl -XPOST 'http://127.0.0.1:9200/test_app/_refresh' -d '""'
{"ok":true,"_shards":{"total":10,"successful":5,"failed":0}}

深入代码,运行时调用的ES后端方法clear_index
是:
def clear(self, models=[], commit=True):
[...]
if not models:
self.conn.delete_index(self.index_name)
else:
[...]
if commit:
self.conn.refresh(index=self.index_name)
哪个看起来不对,因为它会调用conn.refresh
它刚刚删除的索引?

我认为上述错误可能是一个红鲱鱼,因为管理命令将忽略错误并继续,给出这个错误,我认为这个错误更严重:
(.venv)vagrant@precise32:/app$ foreman run ./manage.py update_index --verbosity=3

好的 - 这是我的错,我使用的是旧search_indexes.py
文件,我的index_queryset()
方法不正确。我不会关闭它,因为它可能对其他人有用。
