Question

我意识到当我通过本地postfix服务器在localhost网站上发送邮件（信件）时，它们已成功发送，但每次我需要包含存储在我的徽标中的字母链接：

公共/ castle.jpg

应用程序/邮寄者/的 review_mailer .RB：

class ReviewMailer < ApplicationMailer
  default from: 'no-reply@kalinin.ru'

  def welcome_email(review)
    @review = review
    mail(to: 'bla@bla.ru', subject: 'New review create')
  end  
end

视图/ review_mailer /的 welcome_email .html.erb：

<!DOCTYPE html>
<html>
  ...........................
    <p>logo: <%= image_tag 'public/castle.jpg' %></p>
  </body>
</html>

application.rb中：

config.action_mailer.default_url_options = { host: 'localhost' }

development.rb：

  config.action_mailer.raise_delivery_errors = false
  config.action_mailer.delivery_method = :sendmail
  config.action_mailer.default_url_options = { :host => 'localhost:3000' }

reviews_controller：

  def create
    @review = current_user.reviews.build(review_params)
    if @review.save
      ReviewMailer.welcome_email(@review).deliver_now
      redirect_to root_path
  end

创建新评论后，这是控制台输出：

邮件（信件）没有被发送，可能是什么错误？

Answer 1

我认为你应该在你的环境文件中写这个：

config.action_mailer.asset_host = "http://localhost:3000"

或

config.asset_host = 'http://localhost:3000'

这将暗示下一个配置：

config.action_controller.asset_host = 'http://localhost:3000'
config.action_mailer.asset_host = 'http://localhost:3000'
