ruby-on-rails-3 - 使用轮胎持久性时出错

Question

我有一个带有简单模型的 ActiveAdmin 应用程序，我想在使用轮胎的弹性搜索中坚持：

class Person
  include Tire::Model::Persistence

  property :firstName
  property :lastName
end

但我在索引操作中收到此错误：

NoMethodError (undefined method `quoted_table_name' for Person:Class)

我错过了什么？

Answer 1

首先，我跳过了启用轮胎持久性的几个步骤。感谢Chris Berkhout 关于这个主题的帖子，我的模型现在看起来像这样：

class Person
  include Tire::Model::Persistence
  include Tire::Model::Search
  include Tire::Model::Callbacks

  index_name ES_INDEX_NAME

  # Refresh ES so any changes are immediately visible
  refresh = lambda { Tire::Index.new(ES_INDEX_NAME).refresh }
  after_save &refresh
  after_destroy &refresh

  property :firstName
  property :lastName
  property :updated_at

  before_save { |n| n.updated_at = Time.now }

  def self.touch_es
    # Ensure a mapping in a fresh index, so that Note.all can sort on updated_at
    n = Person.new
    n.save
    n.destroy
  end

  def self.all
    # Override so that Note.all comes back sorted on updated_at, rather than _id
    search { sort { by :updated_at, 'desc' } }
  end

  def self.q(q)
    search { sort { by :updated_at, 'desc' }; query { string q } }
  end

end

我需要在 lib/tasks 中添加一个 es.rake 任务来设置索引：

namespace :es do
  desc "Delete the ElasticSearch index for the current environment"
  task :drop => :environment do
    Tire::Index.new(ES_INDEX_NAME).delete
  end
  desc "Create the ElasticSearch index for the current environment"
  task :create => :environment do
    Tire::Index.new(ES_INDEX_NAME).create
    Person.touch_es
  end
end

以及 config/initializers 中的初始化程序 es.rb 来定义索引名称：

ES_INDEX_NAME = "#{Rails.application.class.parent_name.downcase}_#{Rails.env}"

工作一种享受！

至于尝试让 ActiveAdmin 与 ES 持久性一起工作，我看到 AA 与 ActiveRecord 相关联，尽管 ActiveModel 或独立于 ORM 的版本正在开发中。
