ruby-on-rails - 如何使用 ActionMailer 发送 html 电子邮件？

Question

使用 rails 2.3.14

我的电子邮箱: 数据.html.erb:

<% @data.each do |error| %>
    <table>
        <% error.each_pair do |k, v| %>
            <tr>
                <td>
                    <%= k %>
                </td>
                <td>
                    <%= ap v %>
                </td>
            </tr>   
        <% end %>
    </table>
    <br />
<% end %>

我可以收到电子邮件，但当我收到时，它显示为纯文本，而不是呈现 HTML。

Action Mailer 配置:

config.action_mailer.raise_delivery_errors = true

# Send emails during development
config.action_mailer.perform_deliveries = true
ActionMailer::Base.delivery_method = :sendmail

更新:必须在我的交付方式中指定内容类型:

 def data(data, sent_at = Time.now)
    Time.zone = 'Eastern Time (US & Canada)'

    content_type 'text/html'
    subject     "[#{RAILS_ENV}] An error has occurred - #{Time.now.to_s("%B %d, %Y")}"
    recipients  "bugs@mydomain.com"
    from        AppConfig['from_email']
    sent_on     sent_at
    @body   =   {:data => data}
  end

来自 d11wtq 的 comment :

将 content_type 指定为 text/html:

ActionMailer::Base.mail(
  content_type: "text/html",
  from: "sender@example.com",
  to: "your_email@example.com",
  subject: "This is a test",
  body: "<h2>HTML Email Test</h2><p>This is a <b>test</b>.</p>"
).deliver_now
