我已将Sunsport Solr添加到我的Rails应用程序中。搜索时我收到此错误。

我的型号代码Ad.rb

class Ad < ActiveRecord::Base
validates_presence_of :name
validates_numericality_of :price
validates_numericality_of :seller_id
validates_format_of :email, :with => /\A([^@\s]+)@((?:[-a-z0-9]+\.)+[a-z]{2,})\Z/i
searchable do
text :name
end
end

我的控制器代码ads_controller.rb

 def find
 @ads = Ad.search do
 fulltext params[:search]
 end.results
 end

的routes.rb

 post '/ads/find' => 'ads#find'

布局/ application.erb

<span align="right">
<%= form_tag "/ads/find" do %>
<%= text_field_tag :search_string %>
<%= submit_tag 'Search'  %>
 <% end %>
</span>

我的观点find.html.erb

 <% @ads.each do |ad| %>
