Sendgrid是否需要邮件gem，以及如何使用动作邮件程序进行设置？

Heroku文档说：https : //devcenter.heroku.com/articles/sendgrid#ruby-rails

To send out emails through SendGrid, you need to configure the Mail class to have the correct values:
require 'mail'

Mail.defaults do
  delivery_method :smtp, {
    :address => 'smtp.sendgrid.net',
    :port => '587',
    :domain => 'heroku.com',
    :user_name => ENV['SENDGRID_USERNAME'],
    :password => ENV['SENDGRID_PASSWORD'],
    :authentication => :plain,
    :enable_starttls_auto => true
  }
end

Mail gem docs或heroku都没有明确指定Mail类应该在哪里以及如何配置它。

过去我只是使用Action Mailer这样的东西

class UserMailer < ActionMailer::Base
  default from: '[email protected]'

  # Subject can be set in your I18n file at config/locales/en.yml
  # with the following lookup:
  #
  #   en.user_mailer.signup_confirmation.subject

  def signup_confirmation(user,subject_param='Welcome!')
    @user = user

    mail to: user.email,
         subject: subject_param  do |format|
         #format.text {render __method__}
         format.html {render __method__}
    end
  end

end

关于发生了什么变化以及如何在Herouku / Rails4.1上设置sendgrid的任何很好的例子？

法赞

Heroku为sendgrid提供添加。https://elements.heroku.com/addons/sendgrid

通过添加此选项，它将自动为您设置环境变量，即SENDGRID_USERNAME SENDGRID_PASSWORD

设置加载项后，您必须将其放入production.rb

ActionMailer::Base.smtp_settings = {
 :user_name => ENV['SENDGRID_USERNAME'],
 :password => ENV['SENDGRID_PASSWORD'],
 :domain => 'appname.herokuapp.com',
 :address => "smtp.sendgrid.net",
 :port => 587,
 :authentication => :plain,
 :enable_starttls_auto => true
}

Mailer类将保持与通常使用的类相同。
