Rails 3 Routing Constraint and Regex

Question

I\'m looking to match the pattern state/city in the path, unless the state variable equals \"auth\"

match \'/:state/:city\' => \'cities#index         


        

Answer 1

Based on mu is too short's comments, here is the answer I've come up with:

match '/:state/:city' => 'cities#index', :as => :state_cities, :constraints => OmniauthPassThru.new

lib/omniauth_pass_thru.rb

class OmniauthPassThru
    def initialize
        @passthru = ["/auth/facebook", "/auth/twitter"]
    end

    def matches?(request)
        return false if @passthru.include?(request.fullpath)
        true
    end
end
