where can I find the code where rails connects to the database when booted

Question

Can someone point me to the code where rails reads the database.yml file to connect to the database when booted. I am using Rails 2.3.3

thanks, ash

Answer 1

It's loaded in lib/initializer.rb (around line 900 in rails 2.3.5):

# Loads and returns the contents of the #database_configuration_file. The
# contents of the file are processed via ERB before being sent through
# YAML::load.
def database_configuration
  require 'erb'
  YAML::load(ERB.new(IO.read(database_configuration_file)).result)
end
