Mailer method missing

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…

NoMethodError: undefined method `request_admin_approval’ for

SiteMailer.method_defined? :request_admin_approval
=> true

It is true… there is a method named request_admin_approval for SiteMailer… but it is an instance method (as in:
s =

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.
