子文件夹中的Rails邮件程序和邮件程序视图不起作用

我有一个邮件发送器，可以在日志中看到它正在发送，但是邮件正文中没有包含邮件发送器视图中的任何内容。

这是由于我已将内容放入子文件夹，并且尝试:template_path在mail函数中使用，但无济于事。

app / mailers / marketing / marketing_mailer.rb

class Marketing::MarketingMailer < ActionMailer::Base

    require 'mail'
    address = Mail::Address.new "test@example.com" # ex: "john@example.com"
    address.display_name = "Text" # ex: "John Doe"
    # Set the From or Reply-To header to the following:
    address.format # returns "John Doe "
    default from: address

    # Sends an email when someone fills out the contact form
    def contact(name, email, message)
        @name = name
        @email = email
        @message = message
        mail(:subject => "Test", :to => 'test@example.com', :reply_to => @email) # <== I've tried using :template_path => 'marketing', 'marketing/marketing_mailer', etc, but none worked.
    end
end

/app/views/marketing/marketing_mailer/contact.html.erb

  
    
  
  
    
Name: <%= @name %>
    
Email: <%= @email %>
    
Message: <%= @message %>
  

我注意到devise在/ views / devise / mailers / ...中有邮件视图，所以我知道这是可能的，但是我不确定如何。
