ActionController::UrlWriter

Write URLs from arbitrary places in your codebase, such as your mailers.

Example: 

  class MyMailer
    include ActionController::UrlWriter
    default_url_options[:host] = 'www.basecamphq.com'

    def signup_url(token)
      url_for(:controller => 'signup', action => 'index', :token => token)
    end
 end

In addition to providing url_for, named routes are also accessible after including UrlWriter.

How to deal with Missing host to link to!

You just need to define default_url_options[:host] in your class. The easiest way to do it:

class SomeClass include ActionController::UrlWriter default_url_options[:host] = YourApp::Application.config.action_mailer.default_url_options[:host]

def some_method

some_superb_url(maybe_even_some_variable_here) end end
