Rails __elasticsearch __。create_index！ “根映射定义具有不受支持的参数（mapper_parsing_exception）”

Question

在使用Business.__elasticsearch__.create_index!时，我在使用 elasticsearch-rails 时遇到了麻烦：

  

{“错误”：{“ root_cause”：[{“类型”：“ mapper_parsing_exception”，“原因”：“根映射定义具有不受支持的参数：[业务：{动态=真，属性= {id = {类型= integer}}}]“}]]”“类型”：“ mapper_parsing_exception”，“原因”：“无法解析映射[_doc]：根映射定义具有不受支持的参数：[业务：{dynamic = true，properties = {id = {type = integer}}}]“，” caused_by“：{” type“：” mapper_parsing_exception“，” reason“：”根映射定义具有不受支持的参数：[业务：{dynamic = true，properties = {id = { type = integer}}}]“}}，”状态“：400}

该请求的后面是：

  

PUT http://localhost:9200/development_businesses [状态：400，请求：0.081s，查询：不适用]   {“ settings”：{“ index”：{“ number_of_shards”：1}}，“ mappings”：{“ business”：{“ dynamic”：“ true”，“ properties”：{“ id”：{“ type” ：“整数”}}}}}

我的模型代码：

`
after_save :reindex_model
Elasticsearch::Model.client = Elasticsearch::Client.new url: ENV['BONSAI_URL'], log: true
include Elasticsearch::Model
include Elasticsearch::Model::Callbacks
index_name [Rails.env, model_name.collection.gsub('///', '-')].join('_')
document_type self.name.downcase
`

我已经定义了映射：

`
settings index: { number_of_shards: 1 } do
    mappings dynamic: 'true' do
        indexes :id, type: 'integer'
    end
end
`

Answer 1

在创建映射时删除零件{"business":{"dynamic":"true"}}。尝试像下面这样对我来说很好-

PUT /development_businesses/
{
  "settings": {
    "index": {
      "number_of_shards": 1
    }
  },
  "mappings": {
      "properties": {
        "id": {
          "type": "integer"
        }
      }
  }
}

Answer 2

从ES 7开始，已删除映射类型。您可以阅读更多详细信息here

如果您使用的是Ruby On Rails，则意味着您可能需要从模型或关注点中删除document_type。

作为映射类型的替代方法，一种解决方案是对每种文档类型使用索引。

之前：

module Searchable
  extend ActiveSupport::Concern

  included do
    include Elasticsearch::Model
    include Elasticsearch::Model::Callbacks
    index_name [Rails.env, Rails.application.class.module_parent_name.underscore].join('_')
    document_type self.name.downcase
  end
end

之后：

module Searchable
  extend ActiveSupport::Concern

  included do
    include Elasticsearch::Model
    include Elasticsearch::Model::Callbacks
    index_name [Rails.env, Rails.application.class.module_parent_name.underscore, self.name.downcase].join('_')
  end
end
