To interact with multiple databases you can use Connection Ninja. Please follow this link. There you can see that works even with rails 3, just install it using:

gem install connection_ninja

Hope that helps,

Thanks for reply. But once i generated model. I have mentioned in migration file like require 'connection_ninja' use_connection_ninja(database_name). Now i run rake db:migrate then it is throwing error like undefined method `use_connection_ninja' for main:Object. what i need to do now?

Please note that you must use it not in migrations but in Models: class MyModel < ActiveRecord::Base use_connection_ninja(:other_database) end There is a good abstraction to use it along many models in the link I mentioned to you. Hope that helps
