NoMethodError: `initialize': undefined method `session_class=' for ActiveRecord::SessionStore:Module

[toshitapandey]

I recently upgraded from Rails 3.2 to Rails 4. I am getting following error now:

/usr/share/rvm/gems/ruby-2.3.7@m3/gems/rubycas-client-2.3.10.rc1/lib/casclient/tickets/storage/active_record_ticket_store.rb:20:in 'initialize': undefined method 'session_class=' for ActiveRecord::SessionStore:Module (NoMethodError)

When I looked a bit into it, I found that for rails/activerecord-session_store, method of setting session has changed: Active record session store commit

But, this gem hasn't updated it. The gem still uses following code:
active record ticket store and storage

There is another gem for rubycas-client which uses something like this: mdsol | rubycas-client's storage

As per #78, some folks can use it and others can not. Can someone confirm if this is compatible with Rails 4 (specifically Rails 4.0.8) and if yes, what steps are required to fix thee issue?

I hope this will resolve your issue: rails/activerecord-session_store@4ecd3f7#lib/action_dispatch/session/active_record_store.rb
