Question

I have two models, an School model and Price model. Every school has a price. I would like to return in the search result school with its prices. I am using rails and sunspot.

School-controller:

class SchoolsController < ApplicationController
def index
 @query = params[:search]
 @search = School.search do 
   fulltext params[:search]
     paginate :page => params[:page], :per_page => 7
   end
 @results = @search.results
end
end

School-model:

class School < ActiveRecord::Base
 has_many :prices
 # sunspot search
  searchable do
   text :name, :locality
  end
end

Index – view

<% for result in @results %>
   <tr>
    # School name, from the school-model
    <td><h3><%= link_to result.name, result %></h3></td>
    # School price, from the price-model
    <td><h3><%= result.prices.min %> kr</h3></td>
   </tr>
<% end %>

How do I return for every school its prices, with sunspot?

Answer 1

Maybe you can do eager loading with :include:

@search = School.search(:include => :prices) do # or :include => :price, depends on the relation
 fulltext params[:search]
 paginate :page => params[:page], :per_page => 7
end

Additionnal:

If a School can only have one Price, you should replace has_many :prices with has_one :price in your School model. After doing this, you could access to the price you want by doing this: result.price.min (take a look at number_to_currency, you could be interested in this Helper)
