elasticsearch - elasticsearch_dsl TypeError:index()缺少1个必需的位置参数: 'doc_type'

Question

class Article(Document):
    title = Text(analyzer='snowball', fields={'raw': Keyword()})
    body = Text(analyzer='snowball')
    tags = Keyword()
    published_from = Date()
    lines = Integer()

    class Index:
        name = 'blog45'
        settings = {
          "number_of_shards": 2,
        }

    def save(self, ** kwargs):
        self.lines = len(self.body.split())
        return super(Article, self).save(** kwargs)

    def is_published(self):
        return datetime.now() >= self.published_from

# create the mappings in elasticsearch
Article.init()

# create and save and article
article = Article(meta={'id': 42}, title='Hello world!', tags=['test'])
article.body = ''' looong text '''
article.published_from = datetime.now()
article.save() ### BOMBS HERE!!! ###

我的save()总是抛出错误:

TypeError: index() missing 1 required positional argument: 'doc_type'

上面的示例来自文档，但无法正常工作。如何指定[doc_type]？

在elasticsearch-py中，

res = elastic_client.index(index="bb8_index", body=doc, doc_type='_doc')

截至2020年2月1日:

我将避免使用elasticsearch_dsl库，因为它无法将文档保存/索引到Elasticsearch。该库与最新的Elasticsearch(7.5+)不兼容。

使用常规的elasticsearch-py库
