I wanted to help out a open source project by migrating from 3 to 3.1

But I have never had to migrate a large project before so I am looking for some advise ?

this is the project - https://github.com/locomotivecms/engine

Thanks, Alex

here it is an "almost working" locomotivecms code, migrated on rails 3.1:

https://github.com/lgs/engine/tree/rails-3.1

... it is not ready for pull request,

infact it miss to replace /images/ whith /assets/ in all the relative path ..., anyway it start and stay up (despite many "DEPRECATION WARNING"), on rails 3.1 server:

Rails console works fine as well :

Reposting from GitHub:

It looks like the new sessions in 3.1 require 4 params: https://github.com/rails/rails/blob/master/actionpack/lib/action_dispatch/middleware/session/cookie_store.rb Line 61

def set_session(env, sid, session_data, options)

The store in locomotive only takes three: https://github.com/lgs/engine/blob/rails-3.1/lib/locomotive/session_store.rb Line 31 def set_session(env, sid, session_data)

Looks like options are being passed also that we are not expecting.
