Ruby app responding until stack goes too deep

I'm at a loss here. I have a fairly simple thing going but seem to run into problems a lot with this. I have straight forward web crawler in the works. People post requests and send it on to the queue. If they want to query whats in the queue: the route is

127.0.0.1:8080/requests/id/1.json

response is the action (def) CrawlerController is controller. request is the model.

Heres the route: (although I don't think its relevant)

  match 'requests/id/:id' => 'crawler#response'

And here is the def within the controller:

  def response
    @request = Request.find(params[:id])
   respond_to do |format|
     #format.html { render :action => "new"}
     format.json { render :json => @request.to_json }
    end
  end

The error I'm getting is stack level too deep. If i look at the console output:

EDIT: lines 21 and 19 are the @respond to do and format.json

pretty strange huh?

Try renaming your method from response to something else. I think response might be used by Rails for something else.

Try renaming your variable from @request to something else. I think @request might be used by Rails for something else.

Also try renaming your action from response to something else. I think response might be used by Rails for something else.
