如果在一项ake忙的任务中也需要,那么在鲁比对铁路实施“利用”模式的职能在哪里?
原标题:Where to put model “utility” functions in Ruby on Rails, if it is also required in a rake task?

这是以下问题的第二部分:

如果将“利用”模式功能引入Rub,则列入铁路。

Problem is, I need access to these utility functions from a rake task as well. Using the accepted technique in in the other thread, I get an "undefined method" error when accessing my model from a rake task.

What is the best way to fix this? Thanks

You probably need to define your rake task as dependent on the Rails environment:

task :my_task => :environment do
  # Will load Rails stack before executing this block

  MyModel.foo
end

The default behavior is to load almost nothing, so you won t have access to your models unless you ask for it.
