Problem
Upgrading an existing Ruby on Rails application from 1.2.3, to 2.0.2, presents few problems. I will try and keep a record of the ones I encounter along the way, here.
Solution
- Change the config/environment.rb to let the application know to use the 2.0.2 gem rail version,
- Run the following to generate the secret key for the application:
- Copy the magic key in a new section in your config/environment.rb as in:
change the following line from:
1 |
RAILS_GEM_VERSION = '1.2.3' unless defined? RAILS_GEM_VERSION |
to:
1 |
RAILS_GEM_VERSION = "2.0.2" unless defined? RAILS_GEM_VERSION |
1 |
rake secret |
1 2 3 4 5 6 7 8 9 10 11 12 |
... # config.log_level = :debug # Your secret key for verifying cookie session data integrity. # If you change this key, all old sessions will become invalid! # Make sure the secret is at least 30 characters and all random, # no regular words or you'll be exposed to dictionary attacks. config.action_controller.session = { :session_key => '_yourapplication_session', :secret => 'long_string_generated_from_rake_secret' } |
