Rails sms_fu error

Question

brendan lims instructions for setting up the sms_fu gem say run either

sms_fu = SMSFu::Client.configure(:delivery => :action_mailer)

or

sms_fu = SMSFu::Client.configure(:delivery => :pony, :pony_config => { :via => :sendmail })

or

PONY_CONFIG = { 
 :via => :smtp, 
 :via_options => {
 :address              => 'smtp.gmail.com',
 :port                 => '587',
 :user_name            => 'username',
 :password             => 'password',
 :authentication       => :plain, 
 :enable_starttls_auto => true,
 :domain               => "localhost.localdomain"
}}
sms_fu = SMSFu::Client.configure(:delivery => :pony, :pony_config => PONY_CONFIG)

I tried the first (assuming actionmailer is set up by default, maybe thats wrong). Then the second (after installing pony and mailing something to be sure it works, which was fine) and the last. No errors show in anthing above. The instructions say after this set up, a command like this is supposed to work

sms_fu.deliver("5558675309","at&t","message")

In all set ups i get this error

NameError: uninitialized constant RAILS_ROOT

from script/rails:6:in `<main>'

How do i solve this.

P.S.

Im on rails 3

• Edit

Now i get, after changing RAILS_ROOT to Rails.root in line 102 of lib/sms_fu/sms_fu.rb (according to Dogbert's answer)

Answer 1

This plugin hasn't been updated for a while. Rails deprecated RAILS_ROOT in favor of Rails.root

You'll need to remove RAILS_ROOT from this file, line 102, and replace with Rails.root

  directory = defined?(Rails) ? "#{RAILS_ROOT}/config" : "#{File.dirname(__FILE__)}/../../templates"

to

  directory = defined?(Rails) ? "#{Rails.root}/config" : "#{File.dirname(__FILE__)}/../../templates"
