Client Database Switching

How to automatically switch client databases using Rails.

This is the code that accompanies my Tutorial on the matter and is based on the orignal solution Mark Somerville wrote at PCCL in 2007.

  2. Create Directory /config/databases in your Rails app root
  3. Create /config/databases/localhost.yml in your Rails app root
  4. With contents:

	prepend_before_filter :choose_database_from_host
