Rails dies when I try to call a method from my Mailer. But I have  
defined my method. What could I have missed? Here is the irb session:

> > p = Person.find(1)  
> > =\> Person data…

> > SiteMailer.request\_admin\_approval§  
> > NoMethodError: undefined method `request\_admin\_approval’ for  
> > SiteMailer:Class

> > SiteMailer.method\_defined? :request\_admin\_approval  
> > =\> true

The method code:

class SiteMailer \< ActionMailer::Base

def request\_admin\_approval(person)  
@subject = ‘Watercooler - New User Notification’  
@body[“person”] = person  
@recipients = “me”  
@from = ‘removed\_email\_address@domain.invalid’  
@sent\_on = Time.now  
@headers = {}  
end

To call your mail methods, you dont call them directly:

SiteMailer.deliver\_request\_admin\_approval(person)

Which sends the email and returns a TMail object.

It is true… there is a method named request\_admin\_approval for  
SiteMailer… but it is an instance method (as in:  
s = SiteMailer.new  
s.request\_admin\_approval(p)  
)

You’re trying to access it as a class method… which means, you would  
need  
to define self.request\_admin\_approval in the SiteMailer class instead of  
just request\_admin\_approval.

Or, you will have to make an instance of your SiteMailer object in order  
to  
call the function.

The method code:
