如何在没有模板的情况下使用rails发送邮件?

In my Rails 3 project, I want to send some simple notification emails. I don't need to make a template for them or do any logic. I just want to fire them off from various places in the system.

在我的Rails 3项目中，我想发送一些简单的通知邮件。我不需要为他们做一个模板或做任何逻辑。我只是想把它们从系统的不同位置发射出去。

If I were doing this in an arbitrary ruby script I would use pony. However, I'd like to still use the rails mail facilities and configuration, so that I get the same reliability and setup that I have for the rest of the mail in my system.

如果我在一个任意的ruby脚本中这样做，我会使用pony。但是，我仍然希望使用rails邮件设施和配置，以便获得与系统中其余邮件相同的可靠性和设置。

What's the most simple way to do this? Ideally there would be some method like

最简单的方法是什么?理想情况下会有一些类似的方法

ActionMailer.send(:to => '[e-mail]', :subject =>"the subject", :body =>"this is the body")

The simplest way to send mail in rails 3 without a template is to call the mail method of ActionMailer::Base directly followed by the deliver method,

在rails 3中不使用模板发送邮件的最简单的方法是调用ActionMailer: Base的邮件方法，

For ex, the following would send a plain text e-mail:

对于ex，以下将发送纯文本电子邮件:

ActionMailer::Base.mail(from: "[e-mail]", to: "[e-mail]", subject: "test", body: "test").deliver

http://api.rubyonrails.org/classes/ActionMailer/Base.html#method-i-mail gives you all the header options and also ideas about the how to send a multipart/alternative email with text/plain and text/html parts directly.

http://api.rubyonrails.org/classes/ActionMailer/Base.html#method-i-mail为您提供了所有的标题选项以及如何使用文本/纯文本和文本/html部分直接发送多部分/替代电子邮件的想法。

Here is little example from Rails Guides which uses render method. I didn't try it, but if it works as render in cotrollers, then you can just use:

下面是使用渲染方法的Rails指南中的一个小示例。我没有尝试过，但是如果它在cotrollers中起渲染作用，那么你可以使用:

render :text => "Your message"

or

或

render :text => my_message

Where my_message is a parameter.

其中my_message是一个参数。

You can just wrap it in a method which you can call from every place you want.

你可以将它封装在一个方法中你可以从任何地方调用它。

Updated Rails 3.2.8

In this version of Rails I had to do it like this:

在这个版本的Rails中，我必须这样做:

def raw_email( email, subject, body )
  mail(
    :to => email,
    :subject => subject
  ) do |format|
    format.text { render :text => body }
  end
end

#3

You can try something like this:

你可以试试这样的方法:

class Notifier < ActionMailer::Base
  def send_simple_message(options)
    mail(options.except(:body)) do |format|
      format.text { render :text => options[:body] }
    end.deliver
  end
end

#4

Rails 5 users may find the accepted answer (using format.text {...}) doesn't work; at least I was getting an exception because Rails was looking for a view.

Rails 5用户可以找到被接受的答案(使用格式)。文本{…})不工作;至少我得到了一个异常，因为Rails正在寻找一个视图。

Turns out there's a section in the Rails Guide called Sending Emails without Template Renderingand all one needs to do is supply :content_type and :body options to mail(). E.g.:

Rails指南中有一个部分叫做发送电子邮件，没有模板渲染，你需要做的就是提供:content_type和:mail()的body选项。例如:

class UserMailer < ApplicationMailer
  def welcome_email
    mail(to: params[:user].email,
         body: params[:email_body],
         content_type: "text/html",
         subject: "Already rendered!")
  end
end
