Rails: best practice to scope queries based on subdomain?

Question

I\'m working on a Rails (currently 2.3.4) app that makes use of subdomains to isolate independent account sites. To be clear, what I mean is foo.mysite.com should show the f

Have you tried defining the default_scope a lambda? The lambda bit that defines the options get evaluated every time the scope is used.

class Page < ActiveRecord::Base
  default_scope lambda do 
   {:conditions => "organization_id = #{Thread.current[:organization]}"}
  end
  # yadda yadda
end

It's essentially doing your third option, by working in tandem with your before filter magic. But it's a little more aggressive than that, kicking in on every single find used on the Page model.

If you want this behaviour for all models you could add the default_scope to ActiveRecord::Base, but you mention a few being a couple of joins away. So if you go this route, you'll have to override the default scopes in those models to address the joins.
