Errno::ECONNREFUSED: Connection refused - connect(2)

If you get this error, one of the reason could be incorrect or no ActionMailer settings. The following structure needs to be present in your production.rb (or whatever config file):

ActionMailer::Base.smtp_settings = {
:address => 'smtp.gmail.com',
:port => 587,
:domain => 'mydomain.com',
:authentication => :plain,
:user_name => 'user@mydomain.com',
:password => 'password'
}

Example:

Setting.all.each do |setting|
define_method setting.name do |*a|
  r = find(:first, :include => :setting, :conditions => ["setting_id = ?", setting.id])
  full_record = (a.length == 0) ? false : a[0]
  full_record ? r : r.value
end
