Where do I put helper methods for ActionMailer views?

Question

I have a method that takes an array of strings and joins them so they do something like this:

>> my_arr
=> [\"A\", \"B\", \"C\"]
>> and_join(m         


        

Answer 1

+1, worked fine, just a little correction:

You have to use module instead of class in the helper file:

# mailer_helper.rb
module MailerHelper
  def and_join(arr)
    # whatever …
  end
end
