params

问题 This question already has answers here : C# 4.0, optional parameters and params do not work together (3 answers) Closed 7 years ago .

Example: MyMethod(string Name, int blah=0).

问题 I'm trying to allow non-signed-in users to change a time of day display, and it seems like the best way would be through params in the url. I have: class ApplicationController < ActionController::Base around_filter :use_time_zone private def use_time_zone(&block) Time.use_zone((params[:time] || Time.zone), &block) end end And this works great for something like 'www.mysite.com?time=Hawaii' However, it cannot handle some of the more intricate ones (e.g. 'Eastern Time (US & Canada)'), plus this

All my attempts to use the 'params' keyword in this context have failed.
