`method_missing': undefined method `mail' for Emailer:Class (NoMethodError)

Didn't have a yahoo account to check, but this configuration has worked with my gmail account:

require 'action_mailer'

ActionMailer::Base.delivery_method = :smtp
ActionMailer::Base.smtp_settings = {
    :address => "smtp.gmail.com",
    :port => 587,
    :authentication => :plain,
    :user_name => "sender@gmail.com",
    :password => "<password>",
    :enable_starttls_auto => true
}

class Emailer < ActionMailer::Base
  def test_email(email_address, email_body)
    mail(to: email_address, from: 'sender@gmail.com', subject: 'action mailer test', body: email_body)
  end
end

Emailer.test_email('recipient@gmail.com', 'This is a test e-mail!').deliver_now

update_rubygems throws undefined method `find_by_path' for Gem::Specification:Class (NoMethodError)

Downgrading my Ruby version to 1.8.7 solved this problem.

Getting undefined method `name' for actionmailer:String when installing Webistrano

This worked for me.

rvm rubygems 1.6.2

Rails NoMethodError (undefined method `humanize' for nil:NilClass) in mail to:

Several suggestions:

• You should use ActionMailer class methods directly instead of instantiating a new mailer with new. This is probably the source of the bug
• Since your NewAnswerNotify is nested under Services, it would also make it less ambiguous to use the root namespace ::NewAnswerNotifyMailer (some people may disagree with me on this one, but I've had so many root namespace bugs in the past that I tend to systematically use the :: prefix now)
• Beware of class loading that works differently for class Services::NewAnswerNotify and module Services class NewAnswerNotification (lots of existing questions on this topic)

module Services
  class NewAnswerNotify
    def send_notify(answer)
      ::NewAnswerNotifyMailer.notify(answer).deliver_now # instead of .new.notify
    end
  end
end

Also some side comments regarding the variables and the english

I would rather use

• Services::NewAnswerNotification
• NewAnswerNotificationMailer
• def send_notification(answer) or def notify(answer)

And maybe one last piece of advice from experience after maintaining a code base in the long run: to be more explicit regarding who you are notifying of what def notify_question_author_of_new_answer because later you might have a notify_question_subscribers_of_new_answer or someone else who might need to be notified (it totally depends on your business model of course, feel free to ignore this remark)
