Question

我在这里遵循本指南：https://launchschool.com/blog/handling-emails-in-rails为我的ruby-on-rails项目设置邮件。

此代码有效：example_mailer.rb

ExampleMailer.sample_email(@user).deliver

当我在控制器中拨打<!DOCTYPE html> <html> <head> <meta content='text/html; charset=UTF-8' http-equiv='Content-Type' /> </head> <body> <h1>Hi <%= @user.username %></h1> <p> Sie haben folgende Tags ausgewählt: <% @user.tag_list.each do |tag| %> <%= tag %> <br> <% end %> <br><br> <% @infosall.each do |info| %> <%= info.name %><br> <% end %><br> </p> </body> </html>时，我会收到一封电子邮件：“这封邮件是通过mailgun-ruby使用Mailgun API发送的”，因为它保存在：text。

现在，我想，这个html.erb或这个text.erb文件是发送的，而不只是：text：

sample_email.html.erb

Hi <%= @user.username %>

Sie haben folgende Tags ausgewählt:
<% @user.tag_list.each do |tag| %>
    <%= tag %>
<% end %>

<% @infosall.each do |info| %>
    <%= info.name %>
<% end %>

sample_email.text.erb

text.erb-file

我需要做什么，所以发送这些文件，而不仅仅是：text？

sample_email.text.erb和sample_email.html.erb位于：app / views / example_mailer

文件example_mailer.rb位于：app / mailers / example_mailer.rb

提前致谢！

编辑：我删除了：文本行和mg_client = Mailgun::Client.new ENV['api_key'] message_params = {:from => ENV['gmail_username'], :to => @user.email, :subject => 'Sample Mail using Mailgun API'} mg_client.send_message ENV['domain'], message_params，现在我有了这个：

2016-02-14T13:28:12.483443+00:00 app[web.1]: ExampleMailer#sample_email: processed outbound mail in 150.3ms

In example_mailer.rb:19:     `mg_client.send_message ENV['domain'], message_params`
In events_controller.rb:26: `ExampleMailer.sample_email(@user).deliver`

但现在，我收到了这个错误：

  config.action_mailer.delivery_method = :smtp
  # SMTP settings for gmail
  ActionMailer::Base.smtp_settings = {
      :port           => 587,
      :address        => "smtp.mailgun.org",
      :domain         => ENV['domain'],
      :user_name      => ENV['username'],
      :password       => ENV['password'],
      :authentication => :plain,
  }

我哪里出错了？谢谢！

Edit2：我的smtp设置：

testOnBorrow=true

更改您的simple_email功能，如下面的

def sample_email(user)
    @user = user
    mail(to: @user.email, subject: 'Sample Email')
end

您还可以通过更改上述功能来定义格式

def sample_email(user)
    @user = user
    mail(to: @user.email, subject: 'Sample Email') do |format|
        format.text
        # or
        format.html
    end
end

如何告诉actionmailer在rails中使用html.erb或text.erb文件格式
