Rails:使用模型关联进行太阳黑子文本搜索,使用:through

Question

如何搜索关联和太阳黑子？

class StaticController < ApplicationController

  def search
    @search = Sunspot.search Business, Service do
      fulltext params[:q]
      paginate :per_page => 10
      order_by_geodist(:location, *Geocoder.coordinates(params[:loc]))
    end
      @biz = @search.results

end

---

class Business < ActiveRecord::Base
  attr_accessible :name
  has_many :services, :through => :professionals

  searchable  do
    text :name #name in business column
    # how to do I get the services?
  end

end

---

class Service < ActiveRecord::Base
  attr_accessible :service
  belongs_to :professional
end

---

class Professional < ActiveRecord::Base
  belongs_to :business
  has_many :services, as: :servicable
end

---

在视图中,我有这个(很多循环)

<%= @biz.each do |b| %>
  <%= b.name %>

  <!-- looping through professionals model -->
  <% b.professionals.each do |prof| %>

    <!-- looping through services model -->
    <% prof.services.each do |s| %>
      <%= s.service %>
    <% end %>

  <% end %>
<% end %>

如果我搜索商业模型中的名称,这是有效的,但如果我在搜索Service模型中的术语,该怎么办？它无法正确显示,因为我的观点仅来自业务方面.如何搜索Service模型,如何创建商业名称？

谢谢

您需要为调用模型中的关联模型创建其他索引才能实现此目的.例如:

class Business < ActiveRecord::Base
 attr_accessible :name
 has_many :services, :through => :professionals

 searchable  do
  text :name #name in business column
  text :services do  # this one for full text search
     services.map(&:service).compact.join(" ")
  end
  string :services , :multiple => true do #this one for exact searches
     services.map(&:service).compact
  end
 end
end 

之后,您可以执行以下查询:

Bussines.search do 
  with(:services, "some_service")
end.execute.results

现在,您不再需要连接mysql表来获取数据.您可以从solr中获取数据.这是solr的最大优势之一.

我希望这说清楚.如果您需要更多详细信息,请随意删除评论.
