rails--rails/actionmailer/CHANGELOG.md

Rails 5.0.0.beta4 (April 27, 2016)

• Disallow calling #deliver_later after making local modifications to the message which would be lost when the delivery job is enqueued.

  Prevents a common, hard-to-find bug like:

  message = Notifier.welcome(user, foo)
  message.message_id = my_generated_message_id
  message.deliver_later
  

  The message_id is silently lost! Only the mailer arguments are passed to the delivery job.

  This raises an exception now. Make modifications to the message within the mailer method instead, or use a custom Active Job to manage delivery instead of using #deliver_later.

  Jeremy Daer

• Removes -t from default Sendmail arguments to match the underlying Mail::Sendmail setting.

  Clayton Liggitt

Rails 5.0.0.beta3 (February 24, 2016)

• Add support for fragment caching in Action Mailer views.

  Stan Lo

• Reset ActionMailer::Base.deliveries after every test in ActionDispatch::IntegrationTest.

  Yves Senn

Rails 5.0.0.beta2 (February 01, 2016)

• No changes.

Rails 5.0.0.beta1 (December 18, 2015)

• config.action_mailer.default_url_options[:protocol] is now set to https if config.force_ssl is set to true.

  Andrew Kampjes

• Add config.action_mailer.deliver_later_queue_name configuration to set the mailer queue name.

  Chris McGrath

• assert_emails in block form, uses the given number as expected value. This makes the error message much easier to understand.

  Yuji Yaginuma

• Add support for inline images in mailer previews by using an interceptor class to convert cid: urls in image src attributes to data urls.

  Andrew White

• Mailer preview now uses url_for to fix links to emails for apps running on a subdirectory.

  Remo Mueller

• Mailer previews no longer crash when the mail method wasn't called (NullMail).

  Fixes #19849.

  Yves Senn

• Make sure labels and values line up in mailer previews.

  Yves Senn

• Add assert_enqueued_emails and assert_no_enqueued_emails.

  Example:

  def test_emails
    assert_enqueued_emails 2 do
      ContactMailer.welcome.deliver_later
      ContactMailer.welcome.deliver_later
    end
  end
  
  def test_no_emails
    assert_no_enqueued_emails do
      # No emails enqueued here
    end
  end
  

  George Claghorn

• Add _mailer suffix to mailers created via generator, following the same naming convention used in controllers and jobs.

  Carlos Souza

• Remove deprecated *_path helpers in email views.

  Rafael Mendonça França

• Remove deprecated deliver and deliver! methods.

  claudiob

• Template lookup now respects default locale and I18n fallbacks.

  Given the following templates:

  mailer/demo.html.erb
  mailer/demo.en.html.erb
  mailer/demo.pt.html.erb
  

  Before this change, for a locale that doesn't have its associated file, the mailer/demo.html.erb would be rendered even if en was the default locale.

  Now mailer/demo.en.html.erb has precedence over the file without locale.

  Also, it is possible to give a fallback.

  mailer/demo.pt.html.erb
  mailer/demo.pt-BR.html.erb
  

  So if the locale is pt-PT, mailer/demo.pt.html.erb will be rendered given the right I18n fallback configuration.
