Ruby on Rails SOLR 两个模型之间的方面

Question

在我的分类应用中，我的“主要”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，我会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。 导航栏通过下拉菜单显示 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！

所以问题就在这里： 在我的Classifieds - index.html.erb 中，我成功实现了 Solr facets ，它们用作过滤器，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，我如何保留构面功能，这意味着他随后与Category controller进行交互

型号：

class Classified < ApplicationRecord


    belongs_to :user
    belongs_to :category


    has_many :photos, dependent: :destroy, inverse_of: :classified

    has_many :favorite_classifieds, dependent: :destroy
    has_many :favorited_by , through: :favorite_classifieds , source: :user #for the favorite_by to work :source is needed

    accepts_nested_attributes_for :photos


    searchable do 
        text :title, :boost => 5
        text :model , :created_month , :make , :make_country , :condition ,:treecat,:cat,:price #TO BE CHANGED TO CURRENCY FORMAT

        time :created_at

        string :treecat
        string :price #TO BE CHANGED TO CURRENCY FORMAT
        string :created_month   
        string :cat
        string :make_country
        string :condition
        string :make    
        string :model
    end

    def cat 
        category.root.name
    end

    def treecat
        category.name unless category.name == category.root.name
    end

    def created_month 
        created_at.strftime("%B")
    end    
end



class Category < ApplicationRecord

    acts_as_nested_set
    has_many :classifieds
end




 Classifieds controller index action 
        def index

            @search = Classified.search do 
                paginate(:page => params[:page] || 1, :per_page => 10)

                active_subcategory = with(:treecat,params[:treecat]) if params[:treecat].present?

                facet(:model)                   
                facet(:make)        
                facet(:make_country)

                facet(:treecat)                 
            end
            @classifieds = @search.results

我是菜鸟，我知道我在 html 中的缩进有问题，抱歉！

Answer 1

好的，我通过嵌套路由并从类别模型中获取一些字段来做到这一点。

    resources :categories do
      resources :classifieds do 
      end
    end

类别型号：

 def nested_classifieds
    Classified.where(category_id: self_and_descendants.select(:id))
end

def nested_categories
    self_and_descendants    
end

        nested_categories << f.id
      end

      @search = Sunspot.search(Classified ) do
