如何使用嵌套模型限制太阳黑子搜索? [英] How to restrict Sunspot search with nested models?

问题描述

我想用 with(:is_available, true) 过滤 Sunspot 搜索结果.这适用于 User 模型，但我无法使其与 Itinerary 模型一起使用.

I want to filter the Sunspot search results with with(:is_available, true). This is working with the User model, but I can't make it work with the Itinerary model.

app/controllers/search_controller.rb:

app/controllers/search_controller.rb:

class SearchController < ApplicationController
  before_filter :fulltext_actions
  private
    def fulltext_actions
      @itineraries = do_fulltext_search(Itinerary)
      @users = do_fulltext_search(User)
      @itineraries_size = @itineraries.size
      @users_size = @users.size
    end
    def do_fulltext_search(model)
      Sunspot.search(model) do
        with(:is_available, true)
        fulltext params[:search]
      end.results
    end
end

app/models/user.rb:

app/models/user.rb:

class User < ActiveRecord::Base
  has_many :itineraries, :dependent => :destroy
  searchable do
    text :first_name, :boost => 3
    text :last_name, :boost => 3
    text :status
    boolean :is_available, :using => :available?
  end
  def available?
    !self.suspended
  end
end

app/models/itinerary.rb:

app/models/itinerary.rb:

class Itinerary < ActiveRecord::Base
  belongs_to :user
  searchable do
    text :title, :boost => 3
    text :budget
    text :description
    boolean :is_available, :using => :available?
  end
  def available?
    !self.user.suspended
  end
end

有什么想法吗?

谢谢！

推荐答案

嗯，我真正的问题是索引.

Well, my real problem was the indexation.

当我更新 User 模型时，我在我的控制器中设置了一个标志(如 user_instance.update_index_flag = true).

When I update the User model, I set a flag (like user_instance.update_index_flag = true) in my controller.

在 User 模型中:

attr_accessor :update_index_flag
after_save :reindex_sunspot
def reindex_sunspot
  if self.update_index_flag
    Sunspot.index(self.itineraries.to_a)
  end
end

就是这样...
