Question

So I am using a SearchController to manage sitewide searches (user queries are full-text searched in two different models), and it works in the rails development server, but it doesn’t work on Heroku. I suspect this means I am committing some sort of MVC or RESTful logic error because I think I have had this issue before with heroku and my localhost server where the latter was more lenient with my code. Should I be using a collection or member route of some sort?

Search Controller:

  def index
    @search = Post.search do
      fulltext params[:search]
    end
    @posts = @search.results
    @search = Group.search do
      fulltext params[:search]
    end
    @groups = @search.results
  end

Route:

resources :search, :only => [:index]

Search form (in HAML):

-form_tag '/search', :method => :get do
        =text_field_tag :search, params[:search], :id => 'searchfield'
        =submit_tag 'search',:name => nil, :id => 'searchbutton'

Heroku Logs from the failed action:

Thanks for your help. Let me know if I should give any more information

Answer 1

Your code is fine, the only problem is that your Heroku application can’t connect to any Solr host.

If you’re using the Websolr addon in Heroku then you should open a support ticket because this should be working. Otherwise, you should run this in the heroku console:

Sunspot.config.solr.url

If that points to “http://127.0.0.1:8983/solr” or similar then that’s your problem. You need that to point to some internet-accessible Solr server.
