Forum: Ruby on Rails Two layouts in one mailer

Hi all,

I'm having problems figuring out how to know which mailer method is 
being
invoked in the layout callback.

In my controller, I have code like this and its working great:

class Users::RegistrationsController < Devise::RegistrationsController
    layout :devise_or_application

    def devise_or_application
        ["edit", "update", "destroy"].include?(params[:action]) ?
"application" : "devise"
    end
end

Now I need the same thing for my mailer, but params[:action] is not
available in mailers. Is there another way to use different layout in 
one
mailer, based on which mailer method is being called, like above?

Mailer in question is a custom Devise mailer (inheriting from default
Devise mailer), so I can't really use different mailer, as Devise allows 
me
to configure only one mailer to be used.

Thanks in advance!
