There are some reasons that you may need link_to in a model. Yes, @andy, it's a violation of MVC, but that doesn't mean you should get points for not answering the question.

@schwabsauce, it's easier than that. The first line isn't even strictly necessary if you do it in an initializer or something. Same thing works for .sanitize and .raw and a whole load of other awesome functions.

ActionView::Base.send(:include, Rails.application.routes.url_helpers)
ActionController::Base.helpers.link_to(whatever)

If you want to use autopaths you may have to do this inside your link_to:

Rails.application.routes.url_helpers.page_path(@page)
