Unable to set/use session variables in ruby on rails controller

Question

Can somebody tell me the right way to set/use session variables in a ruby on rails application from scratch. I am not able to set/use a session variable in my controller bet

Answer 1

Your session cookie settings might be wrong. You should inspect the headers of the response and see what the Set-Cookie header looks like.

It might have a wrong domain or perhaps your cookie is https only and you're on http.

The configuration is usually done in some place like config/initializers/session_store.rb

Myapp::Application.config.session_store :cookie_store, {
  :key =>           '_appname_session_id',
  :path =>          '/',
  :domain =>        nil,   # accepted domain, for example '.example.com'  
  :expire_after =>  nil,   # the session will be expired in X seconds unless active
  :secure =>        false, # if true, cookie is valid only on https
  :httponly =>      true   # if true, javascript can't access the cookie
}

Answer 2

Try this in config/initializers/session_store.rb

AppName::Application.config.session_store :cookie_store, key: '_app-name_session'
