ActionMailer(1.3.5) model problem in my Rails1.2.5

Hi all:    I user the command : ruby script/generate mailer FinanceMailer alert_customer_balance, then ,i have this files:

class FinanceMailer < ActionMailer::Base

  def alert_customer_balance(sent_at = Time.now)     @subject = 'FinanceMailer#alert_customer_balance'     @body = {}     @recipients = 'qiang.zhou@qunar.com'     @from = 'qiang.zhou@qunar.com'     @sent_on = sent_at     @headers = {}   end end

After this ,i start ruby with: ruby script/console。 at this consoel enviroment, i put "FinanceMailer.alert_customer_balance", But system return : NoMethodError: undefined method `alert_customer_balance' for FinanceMailer:Class

        from c:/ruby/lib/ruby/gems/1.8/gems/actionmailer-1.3.5/lib/ action_mailer /base.rb:335:in `method_missing'         from (irb):13

I think maybe some inint method error?

I think my problem is :

FinanceMailer.new

=> nil

That's not how Action Mailer works. If you define the instance method foo, then it creates for you two class methods:

FinanceMailer.create_foo (creates a TMail object representing an email from your foo method) FinanceMailer.deliver_foo (creates and sends an email)
