I get this error after trying to send an email:
can't convert nil into String
I only have one model to send emails:
class MyMailer < ActionMailer::ARMailer
I have put this in config/development.rb:
config.action_mailer.delivery_method = :activerecord require 'action_mailer/ar_mailer'
Where is the problem?
I think the problem is located in ActionView/base, so thats what my log tells.
I hope you've found a solution by now but I got the same error until I double checked the model I was associating with ARMailer and found I had it pointing to my personal email-forming class, not the blank Email class ARMailer desired. Once that was corrected, the error went away and I've been firing emails with no problem.
