Rails 2.1.2 to 2.3.2 problems

I just installed Rails 2.3.2 and tried to upgrade my test app from

2.1.2. After installing Rails 2.3.2, I simply changed the gem version

in my environment.rb file in config directory as shown below:

Specifies gem version of Rails to use when vendor/rails is not present

RAILS_GEM_VERSION = ‘2.3.2’ unless defined? RAILS_GEM_VERSION

The server refuses to start and I get the following stacktrace:

=> Booting Mongrel

=> Rails 2.3.2 application starting on http://0.0.0.0:3000

/usr/local/lib/ruby/gems/1.8/gems/rails-2.3.2/lib/initializer.rb:416:in

Change it back to 2.1.2 and I am fine. Is there something that is

missing? I do a rails -v and it shows that 2.3.2 is installed as shown

below:

bruparel@bcr-d810:~$ rails -v

Rails 2.3.2

Thanks for your time.

Hi, did you update your configs?

rake rails:update

Hello Conrad, I am making good progress towards resolving this, but am not there entirely. Following is my abbreviated environment.rb file. Note that I have commented out the RAILS_GEM_VERSION line so that the latest rails 2.3.2 is loaded.

# Specifies gem version of Rails to use when vendor/rails is not present #RAILS_GEM_VERSION = '2.1.2' unless defined? RAILS_GEM_VERSION

# Bootstrap the Rails environment, frameworks, and default configuration require File.join(File.dirname(__FILE__), 'boot')

Rails::Initializer.run do |config|

  # Add additional load paths for your own custom dirs   config.load_paths += %W( #{RAILS_ROOT}/app/form_builders )

  config.time_zone = 'UTC'

  config.action_controller.session = {     :session_key => '_pizzeria_session',     :secret => '1cac89a5ef8e67d30b297648243baee84a52d16dbbf11690733a73c825da43c327a6552f9498d0fe2ecf29cbc09ebf6115102fe3d26f969909f005dc1da39e09'   }

  require "#{RAILS_ROOT}/lib/active_record_extensions.rb"

end

if I comment out the last require "#{RAILS_ROOT}/lib/active_record_extensions.rb"

statement as shown below:

# require "#{RAILS_ROOT}/lib/active_record_extensions.rb"

and restart the server then it boots and everything works fine except where I need the functionality contained in lib/active_record_extensions.rb file which is as follows:

module ActiveRecord

  class Base     def self.search(search, current_page, search_field)       if search.blank?         paginate(:all, :page => current_page || 1, :per_page => 5)       else         paginate(:all, :conditions => ["#{search_field} LIKE ?", "%#{search}%"], :order => 'name',           :page => current_page || 1, :per_page => 5)       end     end   end

end

Why does Rails 2.3.2 have a problem with it when 2.1.2 does not? The error messages are very misleading and point to some problem with database when there is none?

Figured it out:

Rails 2.3 has a problem with requiring any files within the initializer block as shown below.

Rails::Initializer.run do |config|

  require "#{RAILS_ROOT}/lib/active_record_extensions.rb"

end

Instead, it wants you to put your require statement outside the block as shown below:

Rails::Initializer.run do |config|

   .....

end require "#{RAILS_ROOT}/lib/active_record_extensions.rb"

This works. Why is it so? I do not know. If someone can explain this, I would appreciate it.

Thanks.

ActiveRecord is not loaded at this point. The right place for this sort of stuff is in an initializer (see

for ways where putting it at the bottom of environment.rb can go wrong).
