irbrc.rb

# In your active `rails c` session type

ActiveRecord::Base.logger = Logger.new(STDOUT)
ActiveRecord::Base.connection_pool.clear_reloadable_connections!

# or, in your ~/.irbrc add the following

require 'rubygems'

if ENV.include?('RAILS_ENV') && ENV["RAILS_ENV"] == 'development'
    ActiveRecord::Base.logger = Logger.new(STDOUT)
    ActiveRecord::Base.connection_pool.clear_reloadable_connections!
end
