使用 FOSElastica 为特定实体定义 ElasticSearch 映射

Defining an ElasticSearch mapping for a particular entity with FOSElastica

我目前正在尝试使用 FOSElastica,但在配置方面遇到了问题。我想对我的大部分实体使用序列化程序,但我想为特定实体指定映射,我该怎么做?

我试过定义 "properties" 选项,但是定义了 "serializer" 选项后它似乎忽略了它。

我想做这样的事情,但是 "table_content" 属性被忽略了。

fos_elastica:
    serializer: 
        serializer: jms_serializer
    clients:
        default: { host: localhost, port: 9200 }
    indexes:
        table_content: 
            types: 
                table_content: 
                    properties:
                        id: ~
                    persistence: 
                        driver: orm 
                        model: TAMAS\AstroBundle\Entity\TableContent
        astonomical_object:
            types:
                astonomical_object:
                    serializer:
                        groups: [astonomicalobject]
                        serialize_null: true
                    persistence:
                        driver: orm
                        model: TAMAS\AstroBundle\Entity\AstronomicalObject

所以,事实上,当您在配置文件中手动映射时,FOSElastica 确实可以识别类型,这对我来说是一个错误的理解。但它仍然很乏味,因为我在对象中有对象......

所以,过了一段时间我找到了解决问题的方法:Dynamic templates and Index templates

实际上,我在 ElasticSearch 无法识别某些类型的字段(如日期或 geo_point)时遇到了麻烦,因此我在模板的帮助下将它们强制用于特定命名的字段。

如果您想要我在 FOSElastica 中的配置示例 (doc is here):

fos_elastica:
    serializer: 
        serializer: jms_serializer
    clients:
        default: 
            host: localhost 
            port: 9200
    index_templates: # https://www.elastic.co/guide/en/elasticsearch/reference/6.8/indices-templates.html
        base_template: # this is a custom name for the index template
            client: default
            template: "*" # this is where you define which indices will use this template
            types:
                _doc: # this is where you define which types will use this (_doc stands for every type/documents)
                    dynamic_templates: # https://www.elastic.co/guide/en/elasticsearch/reference/6.8/dynamic-templates.html
                        dynamic_date_template: # this is a custom name for the dynamic field template
                            match_pattern: regex
                            match: created|updated|tpq_date|taq_date
                            mapping:
                                type: date
                        dynamic_location_template:
                            match: location
                            mapping:
                                type: geo_point
