我有一个 STI 模型，我想用 ElasticSearch 和 Tire 进行搜索。我遇到的问题是当轮胎创建映射时，它似乎忽略了第二个模型的自定义分析器。下面是我的模型示例。
class Account < ActiveRecord::Base
attr_accessible :name, :type
include Tire::Model::Search
include Tire::Model::Callbacks
tire.settings :analysis => {
:analyzer => {
"custom_search_analyzer" => {
"tokenizer" => "keyword",
"filter" => "lowercase"
},
"custom_index_analyzer" => {
"tokenizer" => "keyword",
"filter" => ["lowercase","substring"]
}
},
:filter => {
:substring => {
"type" => "nGram",
"min_gram" => 1,
"max_gram" => 20
}
}
} do
mapping do
indexes :id, :type => 'integer', :include_in_all => false
indexes :name, :type => 'string', :search_analyzer => :custom_search_analyzer, :index_analyzer=>:custom_index_analyzer
end
end
def to_indexed_json
hash = {}
hash[:id] = id
hash[:name] = name
hash.to_json
end
end
class StandardAccount < Account
tire.index_name 'accounts'
end
class SuperAccount < Account
tire.index_name 'accounts'
end
当我通过轮胎创建索引时，无论是使用 rake 任务还是通过创建模型，它都会创建映射，但对于继承的模型，它不会将自定义分析器应用于它们。如果我查看映射使用
curl -XGET 'http://127.0.0.1:9200/accounts/_mapping?pretty=1'
我得到：
{
"accounts" : {
"account" : {
"properties" : {
"id" : {
"type" : "integer",
"include_in_all" : false
},
"name" : {
"type" : "string",
"index_analyzer" : "custom_index_analyzer",
"search_analyzer" : "custom_search_analyzer"
}
}
},
"standard_account" : {
"properties" : {
"id" : {
"type" : "long"
}
"name" : {
"type" : "string"
}
}
},
"super_account" : {
"properties" : {
"id" : {
"type" : "long"
}
"name" : {
"type" : "string"
}
}
}
}
}
即使我将映射声明移动到继承的类，它似乎只是创建的第一个模型，它选择了额外的选项。我可以通过 ElasticSearch 手动创建索引，但想知道是否有办法使用 Tire 来创建索引？还是我设置不正确
