如何在Rails 3的模型中使用路由助手？

Question

In a model callback I make an API call and need to give the API some URLs. Those URLs would be easily generated by a routing helper.

The solution given in this answer does not work anymore in Rails 3.

Any solution? Thanks :)

Answer 1

Got an answer from the rails IRC: just add

  include Rails.application.routes.url_helpers

to your model

Answer 2

In Rails 3 you can use:

Rails.application.routes.url_helpers

eg

Rails.application.routes.url_helpers.posts_path
