Ruby on rails 3.2 思考Sphinx 3.1 NameError：在生产模式下未初始化常量

在rails 3.2.17上有一个使用db MySQL的项目。 使用思考狮身人面像3.1。 我在索引中只有两个模型：组和产品

在开发模式下，即使在生产服务器上，一切都可以完美地工作。 我在生产服务器上创建了用于测试的开发数据库

但当我尝试跑步时： 导出RAILS_ENV=生产 rake ts：重建 或 rake ts：配置

我得到一个错误：

app/index/product_index.rb

ThinkingSphinx::Index.define :product, :with => :active_record do
  # fields
#  indexes subject, :sortable => true
#  indexes content
#  indexes author.name, :as => :author, :sortable => true

  # attributes
#  has author_id, created_at, updated_at

    indexes :title_ua
    indexes :title_ru
    indexes :description_ua
    indexes :description_ru
    indexes :brief_ua
    indexes :brief_ru
    indexes :permalink
    indexes :asin
    indexes :article
    indexes :mpn

end

组模型迁移文件：

class CreateGroups < ActiveRecord::Migration
  def change
    create_table :groups do |t|
      t.string     :permalink
      t.integer    :position
      t.string     :title_ua
      t.string     :title_ru
      t.text       :description_ua, default: ''
      t.text       :description_ru, default: ''
      t.text       :content_ua,     default: ''
      t.text       :content_ru,     default: ''
      t.integer    :code_1c
      t.integer    :main_page_position
      t.string     :ancestry
      t.string     :category
      t.references :author
      t.references :update_by_user

      t.timestamps
    end
    add_index :groups, :permalink
    add_index :groups, :ancestry
  end
end

class CreateGroups

如评论中所述，使用threadsafe会导致问题。我以前遇到过这种情况（我认为这与思考Sphinx无关，只是在3.2.x中启用threadsafe时Rails的自动加载和Rake如何协同工作

我使用了以下方法-如果没有rake任务执行任何多线程的任务，我很确定这应该是很好的：

config.threadsafe! unless defined?($rails_rake_task) && $rails_rake_task

详细讨论。

您能分享您的索引定义吗？错误指向group_index.rb文件的第10行-但是，那里没有10行。实际文件中有什么不同吗？我发布了我的组模型迁移文件。但我认为索引文件中没有问题，首先-非常简单，其次-它在deve中工作开发模式。您的生产环境是否启用了线程安全？是的，这就是问题所在！谢谢！！！

config.threadsafe! unless defined?($rails_rake_task) && $rails_rake_task
