I wanted to be able to have things work ‘just like in rails’, so I hacked up a quick script that runs all the migrations in the
require 'rubygems' require_gem 'activerecord' if ARGV =~ /VERSION=d+/ version = ARGV.split('=').to_i else version = nil end @logger = Logger.new $stderr ActiveRecord::Base.logger = @logger ActiveRecord::Base.colorize_logging = false ActiveRecord::Base.establish_connection(:adapter => "mysql", :username => "dbuser", :host => "localhost", :password => "xxx", :database => "yyy") ActiveRecord::Migrator.migrate("files/", version)
It would be even nicer to have a config file, but that should be very easy to do with YML.
I run it like so:
ruby domigrations.rb. I believe that the
Migrator.migrate call isn’t documented, so I don’t know how safe it is to count on it, but for the moment things seem to work quite nicely…
