Elasticsearch的{{3}}面临一个奇怪的问题。
一切正常(索引,查询...),但是有时(并且我无法确定根本原因),查询索引崩溃并出现以下错误:
File "/usr/local/lib/python3.5/dist-packages/django/core/handlers/exception.py" in inner
35. response = get_response(request)
File "/usr/local/lib/python3.5/dist-packages/django/core/handlers/base.py" in _get_response
128. response = self.process_exception_by_middleware(e, request)
File "/usr/local/lib/python3.5/dist-packages/django/core/handlers/base.py" in _get_response
126. response = wrapped_callback(request, *callback_args, **callback_kwargs)
File "/usr/local/lib/python3.5/dist-packages/django/contrib/auth/decorators.py" in _wrapped_view
21. return view_func(request, *args, **kwargs)
File "/home/django/prod/mysite/forum/api.py" in get_topics
66. topics_list = SearchQuerySet().filter(**filter).models(Topic)
File "/usr/local/lib/python3.5/dist-packages/haystack/query.py" in __init__
29. self._determine_backend()
File "/usr/local/lib/python3.5/dist-packages/haystack/query.py" in _determine_backend
55. backend_alias = connection_router.for_read(**hints)
File "/usr/local/lib/python3.5/dist-packages/haystack/utils/loading.py" in for_read
167. return self._for_action('for_read', False, **hints)[0]
Exception Type: IndexError at /forum/api/get-topics/
Exception Value: list index out of range
问题似乎出在_determine_backend
函数上。
我的后端在Django设置文件中以这种方式配置:
HAYSTACK_CONNECTIONS = {
'default': {
'ENGINE': 'haystack.backends.elasticsearch2_backend.Elasticsearch2SearchEngine',
'URL': 'http://127.0.0.1:9200/',
'INDEX_NAME': 'myindex',
},
}
在我的生产服务器(Python 3.5)和我的开发人员(Python 3.6)上都是相同的。
干草堆版本为:
django-haystack==2.8.1
- Django [required: >=1.11, installed: 2.0.6]
- pytz [required: Any, installed: 2018.4]
elasticsearch==2.4.1
- urllib3 [required: <2.0,>=1.8, installed: 1.23]
您经历过这样的事情吗?
提前谢谢!
