Rails - Jun 2005 - Website absolute path & url_for, link_to, image_tag etc

Hi!

How can I make my Rails apps independant of the directory they reside in?

I.e. on my local PC I might develop the app in:
http://localhost/rails-app/public/

on the server I have the app in:
http://www.someserver.com/some-subdir/

Hence I want my app to reference links always correctly, i.e. reference 
them by their absolute path.

Now my problem:
When I do:
 image_tag "/images/people/1.jpg" it returns  
http://localhost/rails-app/public/images/people/1.jpg  --- that works fine

However
 link_to "Link", "/images/people/1.jpg" returns 
http://localhost/images/people/1.jpg --- the /rails-app/public/ part is 
missing

Is there some kind of constant that I can put into my link?
E.g.  link_to "Link", BASE_PATH+"/images/people/1.jpg"




Thanks,
Rob

If you are using apache, then place a symlink to public/ in apache''s 
document tree. Rails will do all the work for you.
If you''re using lighttpd, you can set relative_url_root in your config.
Put something like this in one of you environments:

class ActionController::AbstractRequest
  def relative_url_root() "/some/path" end
end
