Urls with params cause request to be routed to wrong action

So I'm having a strange problem with my rails routing, when I go to the apps index path it's fine but if the index path has any routes it doesn't work. I have a controller that looks something like:

class开发者_Python百科 ThingsController < ApplicationController
  def index
    @things = Thing.search params[:q]
  end

  def show
    @thing = Thing.find params[:id]
  end
end

Pretty generic in my opinion, the search method takes the :q param as its input, here is my routes:

MyApp::Application.routes.draw do
  root :to => "things#index"
  resources :things
end

Any thoughts at why this is happening?

You could add a custom route that passes 'q' along to the controller:

resources :things
map.connect '/things/:q', :controller => :things, :q => :q
root :to => "things#index"

It will match the top first, then move down if it doesn't exist. Then you can call params[:q] no problem.
