Question

我正在使用Django + Haystack + Elasticsearch。

当我向此视图发送请求时

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

引发了这个错误：

    response = callback(request, *callback_args, **callback_kwargs)

    raw_suggest = raw_results['suggest']['suggest']

KeyError: 'suggest'

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

项目/ settings_production.py

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

在制作中，我只使用简单的FastCGI。

这就是让我烦恼的事情：有时候我对这个观点没有错误，一切都运转得很好......

请有人知道发生了什么事吗？

非常感谢！

更新

所以，我将我的整个项目安装在另一台计算机上。经过一些测试后，我确认了：

此问题与我的生产设置无关如上所述;
当弹性搜索服务停止时，不会引发错误;
如果该服务正在运行：
- 当方法Object.objects.all()返回一些QuerySet结果时，我没有错误;
- 当方法Object.objects.all()返回空 QuerySet时，问题仍然存在;

我想这是Haystack的elasticsearch_backend模块中的某种错误。

仍然，我不确定。

是的，这是大海捞针中的一个错误。我已经输入了pull request，但与此同时，选项可以运行：
