BrainBuster Globalized !

Posted by Sandro Paganotti in Ruby on Rails - comments are closed

During the last week I created a small patch that allows Brain Buster Logic Capthca plugin to cooperate with Globalize by asking only questions that match the specified language.

To archive this I’ve changed ‘brain_buster.rb’ as follow:

  ...

  def self.find_random_or_previous(id = nil)
    @loc = (Locale.language_code.to_s.blank? ? "en" : Locale.language_code.to_s)
    if id.nil?
      self.find(random_id(first_id, count(:conditions=>["lang = ?",@loc])),:conditions=>["lang = ?",@loc])
    else
      find(id,:conditions=>["lang = ?",@loc])
    end
  end

  private
 ...

  # return first valid id
  def self.first_id
    if find(:all,:conditions=>["lang = ?",@loc], :order => "id").length == 0 
      @loc = "en" 
    end
    @first_id = find(:all,:conditions=>["lang = ?",@loc], :order => "id").first.id
  end

and then I created a migration which add a ‘lang’ column to the brain buster table:

class BusterAndLanguage < ActiveRecord::Migration
  def self.up
    add_column :brain_busters, :lang, :string, :default=>"en" 
  end

  def self.down
    remove_column :brain_busters, :lang
  end
end

That’s it; now we need just to fill the table with questions and answers for the languages we want to add to our application.
