truncate_html helper inside mailer views with rails 3

[hyperrjas]

I'm using helpers inside mailer views and this it works fine:

class UserMailer < Devise::Mailer

  helper :home
  helper :post
  .
  .
  .
end

However, I need to use truncate_html gem inside mailer views

How can I add this helper to mailer views?

Thanks

Hi,

Add this to the top of your Mailer class:

add_template_helper(TruncateHtmlHelper)

Hope this helps!
