Converting a rails app from 1.2.6 to 2.1

This is the first in a series(???) of posts detailing things that I’ve found in the process of updating rails (and other plugins/gems) for an application.  Due to politics, it’s using JRuby, running inside a JBoss container, with a Derby backend.

Things which are getting updated include:

• Rails
• ActiveRecord-JDBC
• ActiveScaffold
• ActiveScaffoldExport
• Goldspike is being replaced with Warbler

Here’s a list of what I’ve encountered thus far:

1. Due to an issue with older versions of activescaffoldexport, I’d had to explicitly list the plugin order in the environment.rb file.  This is because activescaffoldexport (now named active_scaffold_export) came alphabetically before active_scaffold.  So when I removed goldspike and installed the new plugin, this needed to be updated.
2. I needed to run a rake rails:update to update to the latest version.
3. I needed to edit the environment.rb for active_scaffold — these two lines:
   
   Ruby

   require 'helpers/view_helpers' require 'helpers/controller_helpers'

   1 2	require 'helpers/view_helpers' require 'helpers/controller_helpers'

   
   need to be replaced by:
   
   Ruby

   require "#{File.dirname __FILE__}/lib/helpers/view_helpers" require "#{File.dirname __FILE__}/lib/helpers/controller_helpers"

   1 2	require "#{File.dirname __FILE__}/lib/helpers/view_helpers" require "#{File.dirname __FILE__}/lib/helpers/controller_helpers"

4. Deprecated functions used in various plugins need to be updated/rewritten. Those will be detailed later.

I’ll add updates as I come across them.
