Rails 2.1 migration

2008-06-17T14:25:27+10:00

I've hacked together a simple script for converting timezones from the local timezone to utc for Rails 2.1

#!env ruby
class DummyTable
  def initialize(tablename)
    @@tablename=tablename
  end
  def self.method_missing(m, *args); end
  
  def self.datetime(name,options={})
    puts "execute \"UPDATE #{@@tablename} SET #{name}=CONVERT_TZ(#{name},'SYSTEM','+00:00');\""
  end
end

def create_table(tablename,options,*block)
  dummy_table=DummyTable.new(tablename)
  yield DummyTable
end

def add_index(name,fields,options={}); end

class ActiveRecord;end

class ActiveRecord::Schema
  def self.define(options={}, *block)
    yield
  end
end

require 'db/schema.rb'

Drop this file in the root of your project and just run it with plain Ruby. I wrote it this way so I could avoid ActiveRecord, it will spit out a bunch of execute commands ready for plugging in to a migration
