Question

I want to loop through all the variables stored in the session. I checked and it appears that sessions are stored as a hash:
request.session.kind_of?(Hash) – returns true

I wasn’t sure why the following code didn’t work:
request.session.each {|key, value| puts keys + ” –> ” + value

I am trying to output all session variables as part of a debug view.

Answer 1

Instead of:

request.session.each {|key, value| puts keys + " --> " + value

Use:

request.session.each {|key, value| puts key.to_s + " --> " + value.to_s }
