1. Write Console Methods

在~/.irbrc定義ActvieRecord::Base.connection.select_all方法

1.# ~/.railsrc2.def?sql(query)3.ActiveRecord::Base.connection.select_all(query)4.end1.# ~/.irbrc2.if?ENV['RAILS_ENV']3.load?File.dirname(__FILE__) +?'/.railsrc'4.end

這樣就可以在直接在script/console下面執(zhí)行sql查詢

1.$ script/console2.>> sql?'show databases'

2. Log to the console

ActiveRecord Logger

01.# ~/.railsrc02.def?loud_logger03.set_logger_to Logger.new(STDOUT)04.end05.?06.def?quiet_logger07.set_logger_to?nil08.end09.?10.def?set_logger_to(logger)11.ActiveRecord::Base.logger = logger12.ActiveRecord::Base.clear_active_connections!13.end

ActionPack Logger

view sourceprint?1.# ~/.railsrc2.require?'logger'3.Object.const_set(:RAILS_DEFAULT_LOGGER, Logger.new(STDOUT))

3. Play in the Sandbox

使用sandbox參數(shù)來(lái)啟動(dòng)script/console

1.script/console --sandbox

這樣所有的數(shù)據(jù)庫(kù)修改都會(huì)在退出console時(shí)被恢復(fù)

4. Access Helpers

直接調(diào)用helper方法

1.helper.pluralize(3,?'blind mouse')

調(diào)用自定義的helper方法

1.helper.extends BlogsHelper2.helper.archive_dates
