This is kinda of a basic little helper to tell you if the page that you are on is the one you were looking for

application_helper.rb

module ApplicationHelper  

# A nice way to help the views tell if you are on the current page you want to be on.
  def current_view(params, options = {})
    results = options[:result] || "true"

    valid = true

    options.each do |option|
      for param in params
        if param[0].to_s == option[0].to_s
          unless param[1].to_s == option[1].to_s 
            valid = false
          end
        end
        if options[:ignore]
          options[:ignore].each do |ignore|
            if param[0].to_s == ignore[0].to_s && param[1].to_s == ignore[1].to_s
              valid = false
            elsif ignore[0].to_s == param[0].to_s && ignore[1].to_s == "all"
              valid = false
            end
          end
        end
      end
    end

    if valid
      return results
    end
  end
end
