Question

我有一个Django环境设置为使用ElasticSearch作为我们CMS的后端，这是Wagtail。我安装了最新版本的ES（根据我的CURL时的服务为5.6.5），并使用'wagtail.wagtailsearch.backends.elasticsearch5'作为WAGTAILSEARCH_BACKENDS的'BACKEND'设置我的设置文件。根据我的pip冻结，Wagtail在1.13.1版本上，而弹性搜索Python包是在5.5.2。根据{{3}}的阅读，这一切似乎都是正确的。

我遇到的问题是，当我尝试执行'./manage.py update_index'时，它会给我以下错误：

$ ./manage.py update_index 
Updating backend: default
default: Rebuilding index wagtail__wagtailcore_page
Traceback (most recent call last):

正如我所提到的，ES服务正在运行并给出了对CURL的预期回复。我在这里不知道如何解决这个错误。谷歌搜索错误并没有多大帮助：http://docs.wagtail.io/en/v1.13.1/topics/search/backends.html似乎表明问题可能是'延迟/仅用于模型中具有明确删除的反向关系的字段'，但我已经搜索了我们的代码，我很确定我们根本没有使用only()或defer()，更不用说删除了反向关系的表/字段。任何帮助当然非常感谢！

我发现了麻烦。这个问题不在我们项目的代码中，而是在wagtailgridder（v.9.2.18）中的GridIndexPage类的search_fields中。我知道wagtailgridder的开发者，他将在那里做出必要的改变。谢谢你的帮助，@ gasman！你的建议把我带到了正确的地方。
