Globalize2 and migrations - ruby-on-rails

Question

I have used globalize2 to add i18n to an old site. There is already a lot of content in spanish, however it isn't stored in globalize2 tables. Is there a way to convert this content to globalize2 with a migration in rails?
The problem is I can't access the stored content:
>> Panel.first
=> #<Panel id: 1, name: "RT", description: "asd", proje....
>> Panel.first.name
=> nil
>> I18n.locale = nil
=> nil
>> Panel.first.name
=> nil
Any ideas?

I'm sure you solved this one way or another but here goes. You should be able to use the read_attribute method to dig out what you're looking for.
I just used the following to migrate content from the main table into a globalize2 translations table.
Add the appropriate translates line to your model.
Place the following in config/initializers/globalize2_data_migration.rb:
require 'globalize'
module Globalize
module ActiveRecord
module Migration
def move_data_to_translation_table
klass = self.class_name.constantize
return unless klass.count > 0
translated_attribute_columns = klass.first.translated_attributes.keys
klass.all.each do |p|
attribs = {}
translated_attribute_columns.each { |c| attribs[c] = p.read_attribute(c) }
p.update_attributes(attribs)
end
end
def move_data_to_model_table
# Find all of the translated attributes for all records in the model.
klass = self.class_name.constantize
return unless klass.count > 0
all_translated_attributes = klass.all.collect{|m| m.attributes}
all_translated_attributes.each do |translated_record|
# Create a hash containing the translated column names and their values.
translated_attribute_names.inject(fields_to_update={}) do |f, name|
f.update({name.to_sym => translated_record[name.to_s]})
end
# Now, update the actual model's record with the hash.
klass.update_all(fields_to_update, {:id => translated_record['id']})
end
end
end
end
end
Created a migration with the following:
class TranslateAndMigratePages < ActiveRecord::Migration
def self.up
Page.create_translation_table!({
:title => :string,
:custom_title => :string,
:meta_keywords => :string,
:meta_description => :text,
:browser_title => :string
})
say_with_time('Migrating Page data to translation tables') do
Page.move_data_to_translation_table
end
end
def self.down
say_with_time('Moving Page translated values into main table') do
Page.move_data_to_model_table
end
Page.drop_translation_table!
end
end
Borrows heavily from Globalize 3 and refinerycms.
