Rails get url_for working inside model

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!
