Make a custom helper available to both Mailer and View in Rails 3.1

Question

is this the best way to make a helper available to both Mailer and view in Rails 3.1?

class EventMailer < ActionMailer::Base
  include MailerHelper
  helper :         


        

Answer 1

The rails helpers are supposed to be view helpers.

You will notice that the following code :

class MyController < ApplicationController
    helper :my
end

will make the methods in MyHelper available to the views, but not to your controller actions. include MyHelper will make the helper methods available in the controller.

Summarized :

helper :my and you can use the helpers in your views

include MyHelper and you can use the helpers in your controller

I explained a bit more, but you already answered your question :

class EventMailer < ActionMailer::Base
    include MailerHelper
    helper :mailer

    # rest of the code goes here ...
end

will do what you want and allow you to use your helper in both your mailer and your views.

Hope this helps.
