It was working before installing Sunspot: A Solr-Powered Search Engine for Ruby.
I am working in Ubuntu 10.04.
I d need to see the full stacktrace to be sure, but this is actually probably an unhelpful HTTP connection error message bubbling up out of RSolr (the library the Sunspot uses for the low-level Solr connection). Is Solr running (i.e., did you run rake sunspot:solr:start)? Can you access http://localhost:8982/solr/admin ?
What s probably happening is you re attempting to do a substitution on some variable which you thought you were initializing, but neglected to give a real value.
For instance, if you had a form where for a Message and one of the the properties you want is the content, you would normally retrieve that information in the controller with
params[:message][:content]
And if you wanted to filter it, you would do something like
params[:message][:content].gsub(/<[^>]*>/,"")
But if the user didn t enter anything into the content field, the params[:message][:content] variable wouldn t be set. Therefore it s null and you re attempting to do nil.gsub
