How to use my view helpers in my ActionMailer views?

Question

I want to use the methods I defined in app/helpers/annotations_helper.rb in my ReportMailer views (app/views/report_mailer/usage_report.text.html.erb

Answer 1

in my case for Rails4, i do like this:

# app/mailers/application_mailer.rb
class ApplicationMailer < ActionMailer::Base
  add_template_helper ApplicationHelper
  ...
end

and

# app/mailers/user_mailer.rb
class AccountMailer < ApplicationMailer
  def some_method(x, y)
  end
end

so that you do not have to specify add_template_helper everywhere.
