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 = ‘removed\_email\_address@domain.invalid’  
@from = ‘removed\_email\_address@domain.invalid’  
@sent\_on = sent\_at  
@headers = {}  
end  
end

After this ,i start ruby with: ruby script/consolee$B!#e(B 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

> >

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)
