SOLUTION: Here's an update - I did figure out why my custom constraint
wasn't working correctly and here's the changes I made:
In PersonalizedDomain I changed the self.matches? method from a class
method to an instance method as such:
[code]
# lib/personalized_domain.rb
class PersonalizedDomain
def matches?(request)
case request.host
when "www.#{APP_CONFIG[:domain]}", "#{APP_CONFIG[:domain]}", nil
false
else
true
end
end
end
[/code]
and in routes I did this:
[code]
constraints(PersonalizedDomain.new) do
resources :posts
resources :personalized
end
[/code]
