ruby-on-rails - 思考狮身人面像无法配置开发配置

Question

我已经安装了 thinking sphinx 并且在运行 rake ts:index 之后，它无法配置开发文件。文件已创建，但它是空的。

Tasks: TOP => ts:index

我不确定这是否与我在 indices 文件夹下的 user_index.rb 有关。

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

# attributes
  has user_id, created_at, updated_at, ethnicity, religion

end

这是我的 thinking_sphinx.yml 文件:

development:
  mysql41: 9312
test:
  mysql41: 9313
production:
  mysql41: 9312

如有任何帮助，我们将不胜感激。

这个错误，虽然不清楚，是由于你的属性引用之一不太正确......如果你正在索引 User 模型，那么我猜它没有一个名为 user - 所以，user_id 应该只是 id，而 user.name 应该只是 name:

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

  # attributes
  has id, created_at, updated_at, ethnicity, religion
end
