Added position on Enumeration model....

              r789
            
      class AddEnumerationsPosition < ActiveRecord::Migration

        def self.up

        Jean-Philippe Lang
    
Removed 'not null' constraint on position fields....

              r851
            
          add_column(:enumerations, :position, :integer, :default => 1) unless Enumeration.column_names.include?('position')

        Jean-Philippe Lang
    
Merged Rails 2.1 compatibility branch....

              r1609
            
          Enumeration.find(:all).group_by(&:opt).each do |opt, enums|

        Jean-Philippe Lang
    
Fixed: Migration 71 broken if run with code >= r803 (Enumeration#before_save relies on an attribute added in migration 72)....

              r798
            
            enums.each_with_index do |enum, i|

              # do not call model callbacks

              Enumeration.update_all "position = #{i+1}", {:id => enum.id}

            end
