Question

Title says it all. It’s pretty easy from controllers – just using “view_context”. But it doesn’t work with models.

E.g ApplicationController.new.view_context.url_for yields in: “undefined method ‘host’ for nil:NilClass”

ActionView::Base.new(Rails.configuration.paths["app/views"].first).url_for doesn’t work as well.

Can this be done without so much pain ?

P.S I need it for my Prawn gem! I wanted to generate the PDF from the model. And apart from generating the links inside of it – it is very successful!

Hope for your help! Thanks in advance!

It might depend on Rails version, but generally this method is now defined in Rails.application.routes. It expects you to provide hash with url_options, with :host key among others.
