Question

我一直试图破解一个基本的应用程序，我到了我想发送欢迎信息的地步......我以为我把所有内容排成一行，但它只是不发送。我确信这只是一个基本的错误，但我把头发拉出来了。

应用程序/视图/ user_mailer文件/ welcome_email.html.erb

<!DOCTYPE html>
<html>
  <head>
    <meta content="text/html; charset=UTF-8" http-equiv="Content-Type" />
  </head>
  <body>
    <h1>Welcome to example.com</h1>
    <p>
      You have successfully signed up to example.com,
      your username is:.<br/>
    </p>
    <p>
      To login to the site, just follow this link:
    </p>
    <p>Thanks for joining and have a great day!</p>
  </body>
</html>

配置/环境/ production.rb

Scratch::Application.configure do

....
  # Mandrill Connectivity
  config.action_mailer.smtp_settings = {
    :address   => "smtp.mandrillapp.com",
    :port      => 587, # ports 587 and 2525 are also supported with STARTTLS
    :enable_starttls_auto => true, # detects and uses STARTTLS
    :user_name => "REMOVED",
    :password  => "REMOVED", # SMTP password is any valid API key
    :authentication => 'login', # Mandrill supports 'plain' or 'login'
    :domain => 'yourdomain.com', # your domain to identify your server when connecting
    }
....

应用程序/邮寄者/ user_mailer.rb

class UserMailer < ActionMailer::Base
  default from: "info@overflowapp.com"

  def welcome_mail(email)
    mail(:to => email, :subject => "Welcome to Overflow").deliver
  end
end

应用程序/模型/ user_observer.rb

Class UserObserver < ActiveRecord::Observer
  # We check if it's a new user
  def before_save(user)
    @is_new_record = user.new_record?
    true
   end

  def after_save(user)
  # If it's not a new user we don't want to send them another welcome email
    if @is_new_record then
      UserMailer.welcome_mail(user.email)
    end
  end
end

配置/ application.rb中

....
config.active_record.observers = :user_observer
....

Answer 1

看起来你的user_mailer.rb中的函数被称为welcome_mail，而你的模板被称为welcome_email.html.erb（注意函数名中没有'e'）。添加e，它应该发送。

您还可以尝试支持Mandrill的mailchimp gem：
