[Facebooker-talk] link_to issue when running outside of web server

[Lee Mallabone]

Hi all,

I've created a class that I want to run outside of my web server using
the standard rails "script/runner".

The script works fine, loading ActiveRecord objects etc, until I try
and use the link_to helper.

I've included the following in my class:
    include ActionView::Helpers::UrlHelper
    include ActionController::UrlWriter
but when I try and call link_to I get the following error:

/Library/Ruby/Gems/1.8/gems/actionpack-2.2.2/lib/action_controller/url_rewriter.rb:138:in
`url_for': Missing host to link to! Please provide :host parameter or
set default_url_options[:host] (RuntimeError)

I'm calling link_to like this:
link_to('link test', :canvas => true, :controller => :job, :action =>
:show, :id => user_job)

It almost looks as though facebooker's URL helper methods are not
getting mixed in properly, so it's not picking up facebooker's host or
canvas prefix. Anyone know how to fix this? I've attached a tiny class
that demonstrates the problem in my environment. run it with:
script/runner /path/to/link_to_issue.rb

Regards,
Lee.
