如何从rails gem读取应用程序的cookie

Question

I wrote a gem which will read the cookies of an application that installs my gem. But, I am not able to do that because when I try to add the line cookies[:name] , it is throwing the exception undefined method "cookies" .

How to achieve this? Your help is appreciated.

Answer 1

First of all, applications don't store cookies, only browsers do. That said, you can access those cookies from your controllers. See the documentation on cookies here: http://guides.rubyonrails.org/action_controller_overview.html#cookies

Your question is kind of vague. You might have to share some code to get a quality answer.
