我正在使用 Django + Haystack + Elasticsearch。

当我向这个视图发送请求时

from haystack.views import FacetedSearchView

from .models import Object


class ObjectView(FacetedSearchView):

    def extra_context(self):
        extra = super(ObjectView, self).extra_context()

        if not self.results:
            extra['objects'] = Object.objects.all()
        else:
            searchqueryset = self.form.search()
            results = [ result.pk for result in searchqueryset ]
            extra['facets'] = self.results.facet_counts()
            extra['objects'] = Object.objects.filter(pk__in=results)
            extra['results'] = self.results
        return extra

引发此错误:

  File "/home/deploy/.virtualenvs/deploy/local/lib/python2.7/site-packages/django/core/handlers/base.py", line 115, in get_response
    response = callback(request, *callback_args, **callback_kwargs)

    return self.create_response()

    distance_point=kwargs.get('distance_point'), geo_sort=geo_sort)

  File "/home/deploy/.virtualenvs/deploy/local/lib/python2.7/site-packages/haystack/backends/elasticsearch_backend.py", line 571, in _process_results
    raw_suggest = raw_results['suggest']['suggest']

KeyError: 'suggest'

一个奇怪的事实:只有在项目处于生产设置时才会出现问题,即使我没有更改 settings_production 模块中涉及 Haystack 或 Elasticsearch 的任何内容(URL 键除外)。

项目/settings_production.py

'URL': 'http://0.0.0.0:9200/'

在生产中,我只使用一个简单的 FastCGI。

这就是真正困扰我的地方:有时我在这个视图上没有任何错误,而且一切都很好......

拜托,有人知道发生了什么吗?

非常感谢!

更新:

所以,我在另一台计算机上设置了我的整个项目。经过一些测试,我验证了:

  1. 这个问题与我上面描述的我的生产设置无关;

  2. 停止弹性搜索服务时不会引发错误;

  3. 如果服务正在运行

    • 当该方法Object.objects.all()返回一些 QuerySet 结果时,我没有收到任何错误;
    • 当方法Object.objects.all()返回一个的QuerySet 时,问题仍然存在;

我猜这是 Haystack 的 elasticsearch_backend 模块中的某种错误。

不过,我不确定。

是的,这是大海捞针中的一个错误。我已经提出了一个拉取请求,但与此同时,运行的选项是:

  1. INCLUDE_SPELLING在您的 haystack 设置中设置为,False
  2. 使用我们的分叉:https ://github.com/greenkahuna/django-haystack
