ruby-on-rails - Thinking Sphinx——在配置文件中找不到索引

Question

尝试使用 Thinking Sphinx 进行搜索。已关注 this Railscast通过自制安装 TS 和 MySQL(虽然我在我的应用程序中使用 pg，它显然是必需的)，将这些行添加到我的 gemfile 中:

gem 'mysql2'
gem 'thinking-sphinx'

并将以下内容放入我的模型中，低于其他所有内容

post.rb

class Post < ActiveRecord::Base
    #...

    define_index do 
      indexes content
      indexes :name
    end
end

然后我进入终端并尝试 rake ts:index，但我收到此错误:

 using config file '/Users/<personal>/rails_projects/<personal>/config/development.sphinx.conf'...
    FATAL: no indexes found in config file '/Users/<personal>/rails_projects/<personal>/config/development.sphinx.conf'

Fished around on the internet并没有发现什么可以完全回答这个问题。我试过运行 rake ts:configure(它不会提示)然后 rake ts:index，但它不起作用。

一些背景:我刚刚更改了我的终端 shell (使用 zsh)，这进行了各种奇怪的意外更改。我不得不重新安装bundler，然后重新捆绑安装我所有的gem，然后独立gem install rake。然后我捆绑更新以进行良好的衡量。现在 rake 似乎可以工作了，但我仍然收到错误消息。

错误提示的配置文件:

indexer
{
}

searchd
{
  listen = 127.0.0.1:9306:mysql41
  log = /Users/<personal>/rails_projects/<personal>/log/development.searchd.log
  query_log = /Users/<personal>/rails_projects/<personal>/log/development.searchd.query.log
  pid_file = /Users/<personal>/rails_projects/<personal>/log/development.sphinx.pid
  workers = threads
  binlog_path = /Users/<personal>/rails_projects/<personal>/tmp/binlog/development
}

任何想法发生了什么/答案可能在什么代码中？

有趣的更新 -- 我关注了 this Google Group 上的问答进入我的 rails 控制台并输入“Post.sphinx_indexes.length”，但我得到了这个非常不同的错误作为返回。看起来我的模型以某种方式无法访问 gem？

还将这个问题发布到 Thinking Sphinx Google Group 并在那里得到了答案，所以我将其粘贴在下面。在回答上述问题后，我遇到了另一个错误并在那里进行了跟进，所以如果有人想了解更多信息，this discussion应该希望继续有帮助。

我引用:

Hi Sasha The issue is that Thinking Sphinx's documentation is mostly for v2, but v3 is what you're using (and much better). Index definitions are now located in app/indices - the README is your best source of information (but anything it doesn't cover is probably the same as earlier versions): https://github.com/pat/thinking-sphinx/blob/master/README.textile

Have a read through of that, move your index definition, and you should be good to go. Any further issues, get in touch :)

在那个问题之后，我遇到了这个问题，这显然是因为 Sphinx 无法访问我的 PostgreSQL 数据库。

indexing index 'post_core'...
ERROR: source 'post_core_0': unknown type 'pgsql'; skipping.
ERROR: index 'post_core': failed to configure some of the sources, will not index.
total 0 reads, 0.000 sec, 0.0 kb/call avg, 0.0 msec/call avg
total 0 writes, 0.000 sec, 0.0 kb/call avg, 0.0 msec/call avg

我通过卸载 Sphinx 和两个 gems(thinking_sphinx 和 mysql2)来解决这个问题，然后使用 mysql 和 pgsql 标志 brew 安装 Sphinx，然后重新安装 gems。

在那之后， rake ts:index 就像一个魅力。
