[英]ElasticSearch + Tire how to force term to return same value as in field
我有國家列表,我希望用戶能夠按縣對結果進行排序。 所以我有這個幫手:
def facets_for model, field
ul = ""
links = ""
model.facets[field]['terms'].each do |facet|
links << content_tag('li') do
link_to("#{facet['term']} #{facet['count']}", params.merge(field => facet['term']))
end
end
ul << content_tag("ul", class: field) do
links.html_safe
end
ul.html_safe
結束
並在模型中:
class model
....
mapping do
indexes :country do
indexes :name, :type => :string, index: "not_analyzed"
end
end
def self.search params
...
filter :term, destination: params[:destination] if params[:destination].present?
facet("destination") { terms 'country.name' }
...
end
但
面[“術語”]
始終以小寫形式返回國家/地區名稱。 我可以使用Country.find(facet).name做到這一點,但我認為這是不必要的。 有什么辦法可以存儲與字段中相同的字符串值?
更新
我的映射:
{
"wishes" : {
"wish" : {
"properties" : {
"body" : {
"type" : "string"
},
"country" : {
"properties" : {
"name" : {
"type" : "string"
}
}
},
"country_id" : {
"type" : "string"
},
"created_at" : {
"type" : "date",
"format" : "dateOptionalTime"
}
} ... }}}
您的映射創建不正確,您可以嘗試重新索引數據。
Model.index.delete # to delete index with bad mapping
Model.create_elasticsearch_index # this should create index with mapping defined in Model
之后,您可以嘗試再次運行Model.import
。
