python-3.x - 无法解析 ID 为 'DEMO_54ddab6' 的文档中 [date] 类型的字段 [review_start_datetime]

Question

索引映射

"review_start_datetime" : {
   "type" : "date"
},
"review_start_time" : {
   "type" : "date"
}

类

from elasticsearch_dsl import Document, Date

class DocumentX(Document):
    review_start_datetime = Date(format='yyyy-MM-dd HH:mm:ss',
                            default_timezone="UTC")

创建数据

doc = DocumentX.get('DEMO_54ddab6')
doc.review_start_time = datetime.datetime.now()
doc.review_start_datetime = datetime.datetime.now()
doc.save()

在执行保存方法时，它仅针对 review_start_datetime 字段给出以下错误，而不针对 review_start_time。

elasticsearch.exceptions.RequestError: RequestError(400,'mapper_parsing_exception', "failed to parse field[review_start_datetime] of type [date] in document with id'DEMO_54ddab6'")

Answer 1

通过在索引映射中添加 DateTime 格式，它将解决。

"review_start_datetime" : {
    "type" : "date",
    "format" : "yyyy-MM-dd HH:mm:ss"
},
