django - Elasticsearch 模型 init() 引发关键错误

Question

根据文档，我创建了包含一些模型字段的类，以便稍后执行搜索。我还使用默认参数创建了连接。但是我不能为 UserIndex

调用 init()

from elasticsearch_dsl import DocType, Text, Boolean, Date, Keyword
from elasticsearch_dsl.connections import connections

connections.create_connection(hosts=['localhost'], timeout=20)

class UserIndex(DocType):
    pk = Text()
    phone_number = Text()
    nickname = Text()
    name = Text()
    birth_date = Date()
    class Meta:
        index = 'user'

在执行 UserIndex.init() 命令后出现错误:

  File ".../lib/python3.6/site-packages/elasticsearch_dsl/document.py", line 138, in init
    i.save(using=using)
  File ".../lib/python3.6/site-packages/elasticsearch_dsl/index.py", line 289, in save
    current_settings = self.get_settings(using=using)[self._name]['settings']['index']
KeyError: '*'

您使用的是什么版本的 elasticsearch-dsl？最新版本 (6.3.0) 似乎有问题 (This posted issue seems similar)。

回滚到 6.2.1 为我解决了这个错误。
