What happened to session in rails 4? Why is a hash-shaped mess displayed?

Question

Ruby on Rails

I display the query <%= session.inspect %> in the view and get quite adequate session hash data:

{"session_id"=>"22e0842b51f9e20d8a996081045b61c6", "_csrf_token"=>"ZRfXBRBEn2wKegymFjKyjSm7tS4E39JWoyuHuLs3YMU=", "hi"=>"привет"}

This is the picture in rails 3.2. But in version 4, instead I get not quite pleasant phrases:

Part of the upper text has been cut. Tell me what is the reason, and how can I see the session hash data on version 4?

Answer 1

= session.to_hash

Answer 2

Can't you see the name of the class in "not quite nice phrases"?
Working with the brain, we switch to rubidox in the description of the ActionDispatch::Request::Session class, and lo and behold, we see all the methods of the class, and among them there is the treasured to_hash www.rubydoc.info/docs/rails/4.1.7/ActionDispatch/R.. .

Answer 3

= session[:session_id]
= session[:_csrf_token]
= session[:any_of_your_identifier]

Answer 4

Thank you, but using the key to find the value is NOT what I need. I need a session hash with all my key - values, as in the first code example.
