Access helpers from mailer?

Question

I have trying to access helper methods from a rails 3 mailer in order to access the current user for the session.

I put the helper :application in my mailer class, which seems to work, except the methods defined therein are not available to my mailer (i get undefined errors). Does anyone know how this is supposed to work?

Here's my class:

class CommentMailer < ActionMailer::Base   default :from => "Andre Fournier <[email protected]>"    helper :application end 

Thanks, Sean

Answer 1

To enable you to access application helpers from the ActionMailer views, try adding this:

add_template_helper(ApplicationHelper) 

To your ActionMailer (just under your default :from line).

Answer 2

Use helper ApplicationHelper

class NotificationsMailer < ActionMailer::Base    default from: "Community Point <[email protected]>"   helper ApplicationHelper   helper NotificationMailerHelper    # ...other code... 

NOTE: These helper methods are only available to the Views. They are not available in the mailer class (NotificationMailer in my example).

If you need them in the actual mailer class, use include ApplicationHelper, like so:

class NotificationMailer < ActionMailer::Base    include ApplicationHelper    # ... the rest of your mailer class.  end
