ruby-on-rails - Learn-Rails 教程错误 "An SMTP To address is required to send a message"

Question

我在 Learn Ruby on Rails 上的“发送邮件”部分不断收到错误消息教程。

我试过克隆https://github.com/RailsApps/learn-rails.git在我的本地机器上，但问题仍然存在。

下面是我的代码:

user_mailer.rb

class UserMailer < ApplicationMailer
  default from: "do-not-reply@example.com"

  def contact_email(contact)
    @contact = contact
    mail(to: Rails.application.secrets.owner_email, from: @contact.email, :subject => "Website Contact")
  end
end

development.rb

config.action_mailer.smtp_settings = {
    address: "smtp.gmail.com",
    port: 587,
    domain: Rails.application.secrets.domain_name,
    authentication: "plain",
    enable_starttls_auto: true,
    user_name: Rails.application.secrets.email_provider_username,
    password: Rails.application.secrets.email_provider_password
  }
  # ActionMailer Config
  config.action_mailer.default_url_options = { :host => 'localhost:3000' }
  config.action_mailer.delivery_method = :smtp
  config.action_mailer.raise_delivery_errors = true
  # Send email in development mode?
  config.action_mailer.perform_deliveries = true

secrets.yml

development:
  email_provider_username: <%= ENV["GMAIL_USERNAME"] %>
  email_provider_password: <%= ENV["GMAIL_PASSWORD"] %>
  mailchimp_api_key: <%= ENV["MAILCHIMP_API_KEY"] %>
  mailchimp_list_id: <%= ENV["MAILCHIMP_LIST_ID"] %>
  domain_name: example.com
  owner_email: <%= ENV["OWNER_EMAIL"] %>

我还确保在 .bashrc 文件上正确设置了环境变量。

任何帮助将不胜感激，在此先感谢您!

对于开发，您可以使用 letter opener gem。发送电子邮件后，它会在您的默认浏览器中自动打开。

将以下内容添加到 Gemfile 的开发部分。

gem 'letter_opener'
