how to get the persistent cookie value and session cookie value in rails application

问题

Im developing ruby on rails application. I want to get the persistent cookie value and session cookie value in the application. Can any please guide me on this

I have read that request.session_options[:id] will fetch the session_id, is that the one that is usually stored in session cookie? Please guide me if my way of understanding is wrong.Thanks in advance

回答1:

In Rails, it is simple as calling the session or cookies hash.

# Set a simple session cookie
cookies[:user_name] = "david" 
# Read a cookie 
cookies[:user_name]  # => "david"
# Delete a key
cookies.delete :user_name

The same goes for session. So, the information that you are looking for is probably inside one of these two.

Take a look at the examples at http://www.tutorialspoint.com/ruby-on-rails/rails-session-cookies.htm
