Ruby 在 Rails 两个模型之间的 SOLR 方面
Ruby on Rails SOLR facets between 2 models
在我的分类应用中，我的 "main" 模型是 Classifieds 但我也实现了分类所以 Categories has_many :classifieds
我还用 awesome_nested_set
实现了我的 Categories
我也有 Solr 搜索！
在我的网站 Classifieds - index.html.erb 中，我呈现分类广告，如果使用搜索，我呈现相应的分类广告。
现在我已经实现了一个导航栏，它使用 Category 模型进行导航。
导航栏通过下拉列表显示 Category.roots 和每个根的后代。这导致 Category - show.html.erb ，其中 Classifieds 根据它们所在的 Category 显示！
那么问题来了：
在我的 Classifieds - index.html.erb 中，我已经成功实现了 Solr facets ，它被用作过滤器，但这仅在用户搜索或仅在初始索引中过滤时才有效！所以简单来说，当他与 Classifieds Controller.
互动时
当用户使用导航栏时，我如何保留分面功能，这意味着他随后与 Category controller
